Description

Light-transmitting and absorbing filter, organic electroluminescent display element, and organic electroluminescent display device

[0001] The present invention relates to a light transmission / absorption filter, an organic electroluminescence display element, and an organic electroluminescence display device.

[0002] 2. Description of the Related Art In recent years, organic electroluminescence (OLED) display devices, inorganic electroluminescence display devices (inorganic EL display devices), liquid crystal display devices, and the like have been used as image display devices.

[0003] Liquid crystal display devices (LCDs) are becoming increasingly popular as space-saving, low-power image display devices. Because the LCD panel that displays images is a non-emissive element, LCDs are equipped with a backlight unit located behind the LCD panel to supply light to the LCD panel. OLED display devices (also referred to as "organic EL display devices") display images using the spontaneous emission of OLED elements. Therefore, compared to various display devices such as LCDs and plasma display devices, they offer advantages such as a high contrast ratio, excellent color reproducibility, a wide viewing angle, fast response, and the potential for thinness and lightness. In addition to these advantages, they are also being actively researched and developed as next-generation display devices due to their flexibility. Inorganic EL display devices display images using the spontaneous emission of inorganic EL elements instead of the OLED elements used in OLED display devices. Recent research has raised hopes for the realization of display devices superior to OLED display devices in terms of larger screen sizes and longer lifespans.

[0004] In the development of image display devices, techniques for incorporating light-absorbing filters as components are known. For example, in liquid crystal display devices, when white light-emitting diodes (LEDs) are used as light sources for backlight units, attempts have been made to provide light-absorbing filters to block light of unnecessary wavelengths emitted from the white LEDs. Furthermore, attempts have been made to provide light-absorbing filters in OLED display devices in order to suppress reflection of external light. Patent Literature 1 discloses a method for preventing reflection of external light without reducing the transmittance of display light by combining multiple dyes with different maximum absorption wavelengths.

[0005] As another form of light-absorbing filter incorporated into image display devices, research is also underway on optical filters that combine light-absorbing regions with light-absorbing effects and regions where light absorption has been eliminated (hereinafter simply referred to as "light-absorption-eliminated regions") by eliminating light absorption in desired regions. Generally, non-emissive regions (regions from which display light is not emitted) of OLED display devices often have metal wiring or the like, resulting in higher reflectivity than emissive regions (regions from which display light is emitted). When incorporating an optical filter into an image display device, by arranging the light-absorbing regions on the non-emissive regions of the OLED display device and the light-absorption-eliminated regions on the emissive regions of the OLED display device, it is possible to minimize the decrease in transmittance of display light and improve the anti-reflection effect. For example, Patent Document 2 describes a light-absorbing filter containing a resin, a compound having an acid group, a compound that forms hydrogen bonds with the acid group-containing compound and generates radicals upon irradiation with ultraviolet light, and a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm. The light-absorbing filter described in Patent Document 2 is said to exhibit a high decolorization rate when irradiated with ultraviolet light, and to exhibit almost no absorption (hereinafter also referred to as "secondary absorption") due to the new colored structure associated with the decomposition of the dye by ultraviolet light, thereby achieving high decolorization performance. Patent Document 3 also describes a light-absorbing filter containing a resin, a dye having a main absorption wavelength band in the range of 400 to 700 nm, and a compound that generates radicals when irradiated with ultraviolet light, wherein the dye includes at least one of an azo dye represented by any one of general formulas (i) to (iv) and an indoaniline dye represented by general formula (v). The light-absorbing filter described in Patent Document 3 is said to exhibit an excellent decolorization rate even when irradiated with ultraviolet light at room temperature, and to exhibit almost no secondary absorption when irradiated with ultraviolet light, thereby achieving high decolorization performance.Furthermore, Patent Document 4 discloses a configuration in which, in a multicolor light-emitting organic EL display device, magenta color filters (first dimming layers) are arranged on blue light-emitting sections, red light-emitting sections, and non-light-emitting sections, and the magenta color filters are not arranged on green light-emitting sections, and further, first dimming layers that have selective absorption properties for light of wavelengths intermediate between red light and green light (specifically, the wavelength at which the transmittance is at a minimum exists in the range of 580 to 600 nm) are arranged on the blue light-emitting sections, red light-emitting sections, green light-emitting sections, and non-light-emitting sections.

[0006] International Publication No. 2021 / 066082 International Publication No. 2023 / 068235 International Publication No. 2023 / 234353 International Publication No. 2010 / 150535

[0007] However, the light-absorbing filter described in Patent Document 1 suffers from a problem that the transmittance of display light is impaired when the absorbance is increased to a level that sufficiently suppresses reflection of external light. Furthermore, the methods described in Patent Documents 2 and 3 insufficiently suppress reflection of external light caused by light-emitting sections in display devices, leaving room for improvement. Furthermore, OLED display devices with microcavity structures can improve the color purity of display light, but are known to have high viewing angle dependency, resulting in significant color variations depending on the viewing angle. The multicolor light-emitting organic EL display device described in Patent Document 4 shows a certain improvement effect in reducing color variations due to viewing angle, but insufficient suppression of blue external light reflection results in a color variation in reflected light compared to a display without a dye (the color of the reflected light deviates from neutral).

[0008] That is, the present invention has an object to provide a light transmission-absorption filter that, when incorporated into a display device, ensures a desired transmittance of display light, and when incorporated into a display device, suppresses reflection of external light, and also suppresses change in the color of reflected light compared to when the filter does not contain a dye (hereinafter referred to as "the color of reflected light is adjusted to be neutral"), and suppresses change in the color of display light compared to when the filter does not contain a dye (hereinafter referred to as "the color of display light is adjusted to be neutral"); an organic electroluminescent display element including this light transmission-absorption filter; and an organic electroluminescent display device including this light transmission-absorption filter or organic electroluminescent display element.

[0009] In view of the above problems, the inventors conducted extensive research and found that by configuring a light-transmitting-absorbing filter exhibiting a desired high light transmittance, which has a first light-transmitting-absorbing portion whose transmittance at specific wavelengths is equal to or greater than a specific value, and a second light-transmitting-absorbing portion whose chromaticity satisfies a specific relationship with the first light-transmitting-absorbing portion, it is possible to suppress external light reflection when the filter is incorporated into a display device, and further adjust the hue of both the reflected light and the displayed light to be neutral.The present invention was completed based on this finding and further research.

[0011] In the present invention, when there are multiple substituents or linking groups, etc. (hereinafter referred to as substituents, etc.) represented by a specific symbol or formula, or when multiple substituents, etc. are specified simultaneously, unless otherwise specified, the respective substituents, etc. may be the same or different from one another. The same applies to the specification of the number of substituents, etc. Furthermore, when multiple substituents, etc. are adjacent (especially when they are adjacent), they may be linked to each other to form a ring, unless otherwise specified. Furthermore, unless otherwise specified, rings, such as alicyclic rings, aromatic rings, and heterocyclic rings, may be further condensed to form a fused ring. In the present invention, unless otherwise specified, with respect to double bonds, if E- and Z-configurations exist in the molecule, they may be either one or a mixture thereof. In the present invention, the term "compound" (including complex) is used to mean not only the compound itself, but also its salts and ions. Furthermore, it also means that compounds with partially modified structures are included as long as the effects of the present invention are not impaired. Furthermore, compounds that are not specified as substituted or unsubstituted may have any substituent as long as the effects of the present invention are not impaired. The same applies to substituents and linking groups. In the present invention, when describing physical properties, etc., by indicating a numerical range, if the upper and lower limits of the numerical range are described separately, any of the upper and lower limits can be appropriately combined to form a specific numerical range. On the other hand, when describing multiple numerical ranges represented using "to", the upper and lower limits forming the numerical range are not limited to the combination of the specific upper and lower limits written before and after "to" as a specific numerical range, but can be a numerical range obtained by appropriately combining the upper and lower limits of each numerical range. In the present invention, a numerical range represented using "to" means a range that includes the numerical values ​​written before and after "to" as the upper and lower limits. In the present invention, the term "composition" includes not only mixtures in which the component concentrations are constant (each component is uniformly dispersed), but also mixtures in which the component concentrations vary within a range that does not impair the intended function. In the present invention, the term "laminated body" includes not only a form in which each layer is laminated directly or via another layer, but also a form in which each layer is bonded to form a laminate structure.In the present invention, having a main absorption wavelength band in the wavelength range of XX to YY nm means that the wavelength showing maximum absorption (i.e., the maximum absorption wavelength) is present in the wavelength range of XX to YY nm. Therefore, as long as this maximum absorption wavelength is within the above wavelength range, the entire absorption band including this wavelength may be within the above wavelength range, or may extend beyond the above wavelength range. Furthermore, when there are multiple maximum absorption wavelengths, it is sufficient that the maximum absorption wavelength showing the greatest absorbance (referred to as the "maximum maximum absorption wavelength" in the present invention) is present in the above wavelength range. In other words, maximum absorption wavelengths other than the maximum maximum absorption wavelength may be present either inside or outside the above wavelength range of XX to YY nm. In the present invention, when simply referring to a "resin," this includes elastomers. In the present invention, "(meth)acrylate" refers to either or both of acrylate and methacrylate, "(meth)acrylic acid" refers to either or both of acrylic acid and methacrylic acid, and "(meth)acryloyl" refers to either or both of acryloyl and methacryloyl.

[0012] The light transmission-absorption filter of the present invention is a light transmission-absorption filter that ensures a desired transmittance of display light when incorporated into a display device, and when incorporated into a display device, external light reflection is suppressed, and the colors of both the reflected light and the display light are adjusted to be neutral. Also, the organic electroluminescent display element of the present invention and the organic electroluminescent display device of the present invention comprise the light transmission-absorption filter of the present invention that ensures a desired transmittance of display light, suppresses external light reflection, and can adjust the colors of both the reflected light and the display light to be neutral.

[0013] FIG. 1 is a schematic cross-sectional view showing an outline of a light transmission-absorption filter I, which is one embodiment of the light transmission-absorption filter of the present invention, and an outline of the positional relationship with a light emitting element.

[0014] [Light transmission-absorption filter] The light transmission-absorption filter of the present invention has a first light transmission-absorption portion and a second light transmission-absorption portion, wherein the transmittance T(460) at a wavelength of 460 nm, the transmittance T(530) at a wavelength of 530 nm, and the transmittance T(620) at a wavelength of 620 nm of the first light transmission-absorption portion each satisfy the relationships described below, and the L of transmitted light between the first light transmission-absorption portion and the second light transmission-absorption portion is ＊ a ＊ b ＊ a in color space ＊ and b ＊ The light-transmitting and absorbing filter satisfies the relationship that at least one of the values ​​has an opposite sign.

[0015] The light transmission / absorption filter of the present invention may be in the form of a film having a certain thickness, and may be a film that stands alone or may be a film arranged on a substrate film or the like. When the film-shaped light transmission / absorption filter of the present invention is observed in the thickness direction, it is sufficient that a first transmission portion and a second transmission portion are present. Furthermore, the light transmission / absorption filter of the present invention may have a single-layer structure or a multi-layer structure of two or more layers, as long as it has the first light transmission / absorption portion (hereinafter simply referred to as the "first portion") and the second light transmission / absorption portion (hereinafter simply referred to as the "second portion"). A multi-layer structure of two or more layers is preferable because it makes it easier to realize the first portion and the second portion having different light transmission / absorption properties. The light transmission-absorption filter of the present invention, which has a multilayer structure of two or more layers, preferably has a structure including two or more layers with different light absorption and transmission properties. Examples of preferred examples include light transmission-absorption filter I, which is obtained by mask-exposing a laminate including a wavelength-selective absorption layer and a light-absorbing and dissipative layer, as described below, with ultraviolet light irradiation, and light transmission-absorption filter II, which includes a laminate including a wavelength-selective absorption layer and a laminate obtained by mask-exposing a laminate including a light-absorbing and dissipative layer with ultraviolet light irradiation. The light transmission-absorption filter of the present invention may have light transmission-absorption sites defined as the first site and the second site, which have different light transmission and absorption properties. The light transmission-absorption filter of the present invention is used by arranging the first site on a light-emitting site (also referred to simply as "light-emitting site" in the present invention) in the display region of an organic electroluminescence display element (OLED display element), and the second site on a non-light-emitting site (such as a substrate, thin metal wires (metal wiring), and black banks (black partition walls), also referred to simply as "non-light-emitting site" in the present invention) in the display region of the OLED display element. As long as the effects of the present invention are achieved, the light transmission / absorption filter of the present invention may further include other light transmission / absorption regions (hereinafter referred to as “other regions”) that have light transmission / absorption properties different from those of the first region and the second region.For example, when an OLED display element has a display area and a non-display area, the first and second areas can be arranged in the display area as described above, and other areas can be arranged in the non-display area (e.g., a frame area surrounding the display area, an area covered by a fixing member such as a housing, etc.). The light transmission and absorption characteristics of the other areas can be adjusted appropriately in accordance with the configuration of the non-display area of ​​the OLED display element. In the present invention, the light-emitting area of ​​the OLED display element refers to the area from which display light is emitted in the display area, and the non-light-emitting area of ​​the OLED display element refers to the area from which display light is not emitted in the display area. Therefore, the first and second areas of the light-transmitting and absorbing filter of the present invention are configured in accordance with the arrangement of the light-emitting and non-light-emitting areas of the OLED display element into which the light-transmitting and absorbing filter of the present invention is incorporated. Furthermore, the light-transmitting and absorbing filter of the present invention typically has a plurality of first areas, corresponding to the number of light-emitting areas of the OLED display element into which the light-transmitting and absorbing filter of the present invention is incorporated. Furthermore, the light transmission-absorption filter of the present invention may have a plurality of the second regions in the filter, depending on the number of non-light-emitting sections of the OLED display element into which the filter is incorporated. Therefore, the provisions relating to the first region, the second region, and the relationship between the first region and the second region in the light transmission-absorption filter of the present invention all apply to a plurality of first regions and a plurality of second regions. For example, a relationship between the first region and the second region: ＊ and / or b ＊ The relationship in which the signs are opposite satisfies the relationship between any of the plurality of first regions and the second region.

[0016] The light transmission-absorption filter of the present invention is a light transmission-absorption filter having the above-mentioned first and second portions, and thus ensures a desired transmittance of display light when incorporated into a display device. When incorporated into a display device, external light reflection is suppressed, and the color of both the reflected light and the color of the display light are adjusted to be neutral. This is believed to be due to the following reasons. That is, the light transmission-absorption filter of the present invention has transmittances at wavelengths of 460 nm, 530 nm, and 620 nm that satisfy the relationships described below (30% or more at wavelengths of 460 nm and 620 nm, and 40% or more at wavelength of 530 nm), thereby ensuring a desired transmittance of display light. In this way, absorption of light in the emission wavelength region of the OLED display element (light centered at 460 nm, 530 nm, and 620 nm) is suppressed, and as a result, a decrease in the utilization efficiency of the display light is suppressed. Furthermore, in the light transmission-absorption filter of the present invention, the first and second portions are arranged to provide a uniform transmittance of the transmitted light. ＊ a ＊ b ＊ a in color space ＊ and b ＊ The sign of at least one of the values ​​of a and b is opposite to that of the other. ＊ and b ＊ ) and the chromaticity of the second part (a ＊ and b ＊ ) are adjusted to be complementary, and as a result, by arranging the first region in the light transmission-absorption filter of the present invention on a light-emitting portion of an OLED display element and the second region on a non-light-emitting portion of the OLED display element, the light transmission-absorption filter of the present invention can be one in which external light reflection is suppressed and the color of the reflected light is adjusted to be neutral. Note that the first region in the light transmission-absorption filter of the present invention has transmittances at wavelengths of 460 nm, 530 nm, and 620 nm that satisfy the relationships described below, and each transmittance is at least 30% or more (at least 40% or more at a wavelength of 530 nm), and therefore is a region that exhibits light transmittance different from that of any of the R (red), G (green), and B (blue) color filters that have transmittances of less than 30% at a wavelength of 460 nm, 530 nm, or 620 nm.

[0017] (Transmittance at Specific Wavelengths of the First Region) In the first region of the light transmission-absorption filter of the present invention, the transmittance T(460) at a wavelength of 460 nm, the transmittance T(530) at a wavelength of 530 nm, and the transmittance T(620) at a wavelength of 620 nm each satisfy the following relationships: T(460) ≥ 30% T(530) ≥ 40% T(620) ≥ 30% Therefore, the first region of the light transmission-absorption filter of the present invention is a region that exhibits light transmittance different from any of the R (red), G (green), and B (blue) color filters, which have a transmittance of less than 30% at a wavelength of 460 nm, 530 nm, or 620 nm. The upper limits of the transmittance T(460) at a wavelength of 460 nm, the transmittance T(530) at a wavelength of 530 nm, and the transmittance T(620) at a wavelength of 620 nm are not particularly limited, and can be, for example, 80% or less, preferably 70% or less, more preferably 65% ​​or less, and even more preferably 60% or less. That is, the ranges of the transmittance T(460) at a wavelength of 460 nm and the transmittance T(620) at a wavelength of 620 nm can be 30 to 80%, preferably 30 to 70%, more preferably 30 to 65%, and even more preferably 30 to 60%, and the range of the transmittance T(530) at a wavelength of 530 nm can be 40 to 80%, preferably 40 to 70%, more preferably 40 to 65%, and even more preferably 40 to 60%. The transmittance T(460) of the first portion at a wavelength of 460 nm is preferably 45% or more, and more preferably 50% or more. That is, the transmittance T(460) at a wavelength of 460 nm is preferably in the range of 45 to 80%, more preferably 50 to 70%, even more preferably 50 to 65%, and particularly preferably 50 to 60%.

[0018] (a between the first and second parts ＊ and / or b ＊ The relationship between the signs of the first and second regions in the light transmission and absorption filter of the present invention is as follows: ＊ a ＊ b ＊ a in color space ＊ and b ＊Specifically, the relationship that at least one of the values ​​has an opposite sign means that the following (1) and / or (2) is satisfied: (1) L of the first portion ＊ a ＊ b ＊ a in color space ＊ The sign of the value of L of the second portion ＊ a ＊ b ＊ a in color space ＊ The signs of the values ​​of the first and second regions are opposite to each other, one being + (plus) and the other being − (minus). ＊ a ＊ b ＊ b in color space ＊ The sign of the value of L of the second portion ＊ a ＊ b ＊ b in color space ＊ The signs of the values ​​of the L and R of the transmitted light are opposite, one being + (plus) and the other being − (minus). ＊ a ＊ b ＊ a in color space ＊ and b ＊ In order to further suppress external light reflection, the L of transmitted light between the first region and the second region in the light transmission / absorption filter of the present invention is set to 0.05, and the L of transmitted light between the first region and the second region is set to 0.05. ＊ a ＊ b ＊ a in color space ＊ and b ＊ It is preferable that the signs of both values ​​of L are opposite to each other, that is, that both of (1) and (2) above are satisfied. ＊ a ＊ b ＊ Color space is the L standardized by the CIE (International Commission on Illumination) in 1976. ＊ a ＊ b ＊ It also means the color space of transmitted light. ＊ a ＊ b ＊a in color space ＊ and b ＊ is a value calculated for each of the first and second regions by multiplying the transmittance of the light transmission / absorption filter in the wavelength range of 380 to 780 nm by the standard relative luminosity factor for photopic vision and then summing the results (luminosity correction). ＊ a ＊ b ＊ a in color space ＊ and b ＊ is the a of transmitted light at a polar angle of 0° and an azimuth angle of 0° ＊ and b ＊ means.

[0019] The first and second portions of the light transmission / absorption filter of the present invention will be described below in order in terms of points other than those mentioned above.

[0020] <<First Region>> The first region of the light transmission-absorption filter of the present invention is used by being disposed on the light-emitting region of an OLED display element. The light-emitting region and non-light-emitting region of the display element are usually disposed with a width of about 10 to 30 μm in one pixel, and when the light transmission-absorption filter of the present invention is applied to an OLED display element, the distance between the light transmission-absorption filter of the present invention and the OLED display element layer is usually set to, for example, about 2 to 40 μm. In such a configuration, the color of the display light is controlled by the a of the first region. ＊ and b ＊ The evaluation of the color of the display light can be substituted by evaluating the a of the transmitted light of the first portion. ＊ and b ＊ is usually such that the following relationship is satisfied: -30.0≦a ＊ ≦+30.0 −30.0≦b ＊ From the viewpoint of adjusting the color tone of the display light to be more neutral, it is preferable to satisfy the following relationship: -20.0≦a ＊ ≦+20.0 −20.0≦b ＊ ≦+20.0 It is more preferable that the following relationship is satisfied: −10.0≦a ＊ ≦+10.0 −10.0≦b ＊≦+10.0 It is more preferable that the following relationship is satisfied: −8.0≦a ＊ ≦+8.0 −8.0≦b ＊ It is particularly preferable that the following relationship be satisfied: -7.0≦a ＊ ≦+7.0 −7.0≦b ＊ ≦+7.0 In addition, a in the formula of this paragraph ＊ and b ＊ is the L of the transmitted light of the first portion ＊ a ＊ b ＊ a in color space ＊ and b ＊ The L of the transmitted light through the first portion is ＊ a ＊ b ＊ a in color space ＊ and b ＊ satisfies the above relationship if a ＊ and b ＊ In addition, whether or not the above relationship is satisfied is determined by rounding off the first decimal place to the nearest tenth. ＊ and b ＊ The decision will be made based on the above.

[0021] <<Second Section>> The second section of the light transmission-absorption filter of the present invention is used by being disposed on a non-light-emitting section of the OLED display element. Therefore, the transmittance of the second section is not particularly limited in a specific wavelength range, as is the case with the first section. From the viewpoint of suppressing external light reflection in the light transmission-absorption filter of the present invention and facilitating adjustment of the color of the reflected light to a neutral color, the a of the transmitted light of the second section is ＊ and b ＊ It is preferable that the following relationship be satisfied: -30.0≦a ＊ ≦+30.0 −30.0≦b ＊ ≦+30.0 It is more preferable to satisfy the following relationship: −25.0≦a ＊ ≦+25.0 −25.0≦b ＊ It is more preferable that the following relationship is satisfied: -20.0≦a ＊≦+20.0 −20.0≦b ＊ ≦+20.0 In addition, a in the formula of this paragraph ＊ and b ＊ is the L of transmitted light through the second portion ＊ a ＊ b ＊ a in color space ＊ and b ＊ The L of the transmitted light through the second portion is ＊ a ＊ b ＊ a in color space ＊ and b ＊ satisfies the above relationship if a ＊ and b ＊ In addition, whether or not the above relationship is satisfied is determined by rounding off the first decimal place to the nearest tenth. ＊ and b ＊ The decision will be made based on the above.

[0022] In the light transmission-absorption filter of the present invention, the area ratio between the first region and the second region corresponds to the area ratio between the light-emitting region and the non-light-emitting region of the OLED display element to which the light transmission-absorption filter of the present invention is applied. That is, the area ratio between the second region (non-light-emitting region of the OLED display element) and the first region (light-emitting region of the OLED display element) is usually second region (non-light-emitting region of the OLED display element) / first region (light-emitting region of the OLED display element)=90 / 10 to 60 / 40, and from the viewpoint of obtaining a light transmission-absorption filter in which external light reflection is suppressed and both reflected color and displayed color are adjusted to be neutral, a ratio of 85 / 15 to 60 / 40 is preferred.

[0023] The reflection color exhibited by the light transmission / absorption filter of the present invention is ＊ a ＊ b ＊ a in color space ＊ and b ＊ It is preferable that at least one of the above is −5.0 to 5.0, and the above L ＊ a ＊ b ＊ a in color space ＊ and b ＊ It is more preferable that both of the above L ＊ a＊ b ＊ a in color space ＊ and b ＊ and more preferably both are -2.0 to 2.0. The reflectance exhibited by the light transmission-absorption filter of the present invention is preferably 8.0% or less, more preferably 7.5% or less, and even more preferably 7.0% or less. There is no particular restriction on the lower limit, and a practical value is 4.0% or more. The L of the reflected light exhibited by the light transmission-absorption filter of the present invention ＊ a ＊ b ＊ a in color space ＊ and b ＊ The reflectance is calculated as the sum of the reflection spectra of the light-emitting portions and the reflection spectra of the non-light-emitting portions multiplied by the area ratio of the light-emitting portions to the non-light-emitting portions, using the method described in the Examples below, and is calculated by multiplying the obtained reflection spectra by the CIE standard illuminant D65 spectrum and the photopic standard relative luminous efficiency and then taking the sum (luminous efficiency correction).

[0024] The thickness of the light transmission-absorption filter of the present invention is not particularly limited and can be, for example, 2 to 130 μm. Light transmission-absorption filter I, described below, preferably has a thickness of 2 to 80 μm, more preferably 2 to 70 μm, and even more preferably 2 to 60 μm. Light transmission-absorption filter II, described below, preferably has a thickness of 5 to 120 μm, more preferably 7 to 110 μm, and even more preferably 9 to 110 μm. The thickness is a value measured based on the method for measuring the film thickness of the light-absorbing and disappearing layer and the wavelength-selective absorption layer, described below.

[0025] As one preferred embodiment of the light transmission-absorption filter of the present invention, a light transmission-absorption filter (hereinafter also referred to as "light transmission-absorption filter I") obtained by mask-exposing a laminate (hereinafter also referred to as "laminate I") including a wavelength-selective absorption layer and a light-absorbing-dissipating layer with ultraviolet irradiation will be described in detail below. Furthermore, as another preferred embodiment of the light transmission-absorption filter of the present invention, a light transmission-absorption filter (hereinafter also referred to as "light transmission-absorption filter II") including a laminate (hereinafter also referred to as "laminate III") obtained by mask-exposing a laminate (hereinafter also referred to as "laminate pre-III") including a light-absorbing-dissipating layer with ultraviolet irradiation will be described in detail. However, the light transmission-absorption filter of the present invention is not limited to these embodiments.

[0026] [Light-Transmitting-Absorbing Filter I] The light-transmitting-absorbing filter I is a light-transmitting-absorbing filter obtained by mask-exposing a laminate I containing a wavelength-selective-absorbing layer and a light-absorbing-disappearing layer with ultraviolet light irradiation. The wavelength-selective-absorbing layer refers to a layer that has light-absorbing properties that are almost the same as those of the wavelength-selective-absorbing layer in the laminate I before mask exposure, regardless of the mask exposure with ultraviolet light irradiation. On the other hand, the light-absorbing-disappearing layer refers to a layer that has the property of being decolorizable by ultraviolet light irradiation due to a chemical change of the dye contained in the light-absorbing-disappearing layer. Therefore, the light-absorbing-disappearing layer in the light-transmitting-absorbing filter I of the present invention has light-absorbing portions that have a light-absorbing effect and portions where light absorption has been eliminated (light-absorbing-disappearing portions) according to the pattern of mask exposure with ultraviolet light irradiation (hereinafter also referred to as the "mask pattern"). The light-absorbing portions can exhibit the desired absorbance. That is, by mask-exposing a laminate I including a wavelength-selective absorption layer and a light-absorbing / dissipating layer by ultraviolet irradiation, the masked portions of the laminate I are not exposed and exist as light-absorbing portions having a light-absorbing effect, while the unmasked portions are exposed, and the light-absorbing / dissipating layer in the unmasked portions is decolorized to become light-absorbing / dissipating portions, resulting in portions with low light absorption. As a result, in the light-transmitting / absorbent filter I, the portions including the wavelength-selective absorption layer and the light-absorbing / dissipating layer in the unmasked portions (light-absorbing / dissipating portions) become the first portions, and the portions including the wavelength-selective absorption layer and the light-absorbing / dissipating layer in the masked portions (light-absorbing portions) become the second portions. In particular, as will be described later, if the light-absorbing / dissipating layer exhibits an excellent decolorization rate and there is almost no secondary absorption associated with dye decomposition, the light-absorbing / dissipating layer in the light-transmitting / absorbent filter I can exhibit optical properties that are close to colorless, and the first portions can exhibit light-absorbing properties specific to the wavelength-selective absorption layer. Unless otherwise specified, the description of laminate I can be preferably applied to light transmission-absorption filter I, except that the layer corresponding to the light-absorbing-disappearing layer in laminate I has a light-absorbing-disappearing site formed by ultraviolet irradiation.As the laminate I, for example, a laminate including a wavelength selective absorption layer, a diffusion-preventing layer described below, and a light-absorbing and dissipating layer arranged in this order can be preferably mentioned.

[0027] [Light-Transmitting-Absorbing Filter II] The light-transmitting-absorbing filter II is a light-transmitting-absorbing filter comprising a laminate III obtained by mask-exposing a laminate pre-III containing a light-absorbing-disappearing layer with ultraviolet light irradiation, and a laminate II containing a wavelength-selective-absorbing layer. The laminate pre-III does not contain a wavelength-selective-absorbing layer, and the laminate II does not contain a light-absorbing-disappearing layer. The wavelength-selective-absorbing layer, like the wavelength-selective-absorbing layer in the light-transmitting-absorbing filter I described above, refers to a layer that has light absorption properties that are almost the same as those of the wavelength-selective-absorbing layer in the laminate II before mask exposure, regardless of the mask exposure with ultraviolet light irradiation. Meanwhile, the light-absorbing-disappearing layer, like the light-absorbing-disappearing layer in the light-transmitting-absorbing filter I described above, refers to a layer that has the property of being decolorized by ultraviolet light irradiation due to a chemical change of the dye contained in the light-absorbing-disappearing layer. Thus, the light-absorbing and dissipating layer in the light transmission-absorption filter II of the present invention has light-absorbing portions with a light-absorbing effect and portions where the light-absorbency has been eliminated (light-absorbing and dissipating portions) according to the pattern of masked exposure by ultraviolet irradiation (hereinafter also referred to as the "mask pattern"). The light-absorbing portions can exhibit the desired absorbance. That is, by masked exposure of a laminate pre-III including a light-absorbing and dissipating layer by ultraviolet irradiation, the masked portions of the laminate pre-III are not exposed and exist as light-absorbing portions with a light-absorbing effect, while the unmasked portions are exposed, and the light-absorbing and dissipating layer in the unmasked portions is bleached to become light-absorbing and dissipating portions, resulting in a laminate III that exists as portions with low light absorption. As a result, in the light transmission-absorption filter II, the portions including the wavelength-selective absorption layer and the light-absorbing and dissipating layer in the unmasked portions (light-absorbing and dissipating portions) become the first portions, and the portions including the wavelength-selective absorption layer and the light-absorbing and dissipating layer in the masked portions (light-absorbing portions) become the second portions. In particular, as will be described later, when the light-absorbing and dissipating layer exhibits an excellent discoloration rate and there is almost no secondary absorption due to the decomposition of the dye, the light-absorbing and dissipating layer in the light-transmitting and absorbing filter II can exhibit optical properties that are close to colorless, and the first portion can exhibit light-absorbing properties that are specific to the wavelength-selective and absorbing layer.In addition, the laminate III in the light transmission / absorption filter II can preferably be described in the description of the laminate pre-III, unless otherwise specified, except that the layer corresponding to the light-absorbing / disappearing layer in the laminate pre-III has a light-absorbing / disappearing portion formed by ultraviolet irradiation. Preferred examples of the laminate II include a laminate having a structure in which a first wavelength-selective absorption layer (described later), a gas barrier layer (described later), and a first wavelength-selective absorption layer (described later) are arranged in this order. Preferred examples of the laminate pre-III include a laminate having a structure in which a diffusion-preventing layer (described later), a light-absorbing / disappearing layer, and a gas barrier layer (described later) are arranged in this order.

[0028] Regarding light transmission-absorption filter I, the positional relationship between the first and second regions in the light transmission-absorption filter of the present invention and the OLED display element, which is a light-emitting element, will be described below with reference to FIG. 1 . Note that the above-described positional relationship is not limited to light transmission-absorption filter I, but also applies to light transmission-absorption filters of the present invention, such as light transmission-absorption filter II. Specifically, as shown in FIG. 1 , light transmission-absorption filter I (10) is obtained by mask-exposing laminate I (not shown), and has a mask-exposed wavelength-selective absorption layer 3 and a mask-exposed light-absorbing bleaching layer 4. In the mask-exposed light-absorbing bleaching layer 4, the unmasked portions become light-absorbency-free portions 5, and the masked portions become light-absorbing portions 6. The mask pattern is applied so as to correspond to the arrangement of the light-emitting portions 7 and non-light-emitting portions 8 of the OLED display element. Specifically, the portions of laminate I located above the light-emitting portions 7 of the OLED display element are masked, and the portions of laminate I located above the non-light-emitting portions 8 of the OLED display element are not masked. As a result, light transmission-absorption filter I (10) has a first region 1 including the mask-exposed wavelength-selective absorption layer 3 and the light-absorbent disappearance region 5 at a location corresponding to the top of the light-emitting region 7 of the OLED display element, and a second region 2 including the mask-exposed wavelength-selective absorption layer 3 and the light-absorbing region 6 at a location corresponding to the top of the non-light-emitting region 8 of the OLED display element. Note that while FIG. 1 shows the mask-exposed light-absorption-discolorable layer 4, the mask-exposed wavelength-selective absorption layer 3, and the light-emitting region 7 of the OLED display element arranged in this order, they may also be arranged in this order. The same applies to light transmission-absorption filters of the present invention, such as light transmission-absorption filter II.

[0029] Hereinafter, a laminate I including a wavelength-selective absorption layer and a light-absorbing and dissipating layer, a laminate II including a wavelength-selective absorption layer, and a laminate pre-III including a light-absorbing and dissipating layer will be described.

[0030] [Laminate I] Laminate I is a laminate including a light-absorbing and dissipating layer and a wavelength-selective absorbing layer. Specifically, it is preferably a laminate including a light-absorbing and dissipating layer containing a resin, a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm, and a compound that generates radicals upon ultraviolet irradiation, and a wavelength-selective absorbing layer containing a resin and a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm but not containing a compound that generates radicals upon ultraviolet irradiation. [Laminate II] Laminate II is a laminate including a wavelength-selective absorbing layer. Specifically, it is preferably a laminate including a wavelength-selective absorbing layer containing a resin and a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm but not containing a compound that generates radicals upon ultraviolet irradiation. However, laminate II does not include a light-absorbing and dissipating layer. [Laminate pre-III] The laminate pre-III is a laminate including a light-absorbing and dissipating layer, and more specifically, it is preferably a laminate including a light-absorbing and dissipating layer containing a resin, a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm, and a compound that generates radicals upon ultraviolet irradiation, provided that the laminate pre-III does not include a wavelength-selective absorption layer.

[0031] In the present invention, unless otherwise specified, the components constituting the light-absorbing and dissipating layer in the laminate I and laminate pre-III (such as resins, dyes, compounds that generate radicals upon ultraviolet irradiation, and other components that may be optionally contained) may each be contained in the light-absorbing and dissipating layer in the laminate I and laminate pre-III, either singly or in combination of two or more. Furthermore, in the present invention, the components constituting the wavelength-selective absorption layer in the laminate I and laminate II (such as resins, dyes, and other components that may be optionally contained) may each be contained in the wavelength-selective absorption layer in the laminate I and laminate II, either singly or in combination of two or more. The same applies to a light transmission-absorption filter I produced using the laminate I and a light transmission-absorption filter II produced using the laminate II and laminate pre-III.

[0032] In the present invention, the main absorption wavelength band of the dye refers to the main absorption wavelength band of the dye measured for the laminate I, for each of the laminates II and pre-III, or for the laminate II and pre-III. Specifically, in the Examples described below, the measurement is performed for the laminate I, for each of the laminates II and pre-III, or for the laminate II and pre-III under the conditions described in "Absorbance Measurement of First and Second Regions." In each of the laminates I, II, and pre-III, the "dye" is dispersed (preferably dissolved) in the resin contained in the same layer (light-absorbing and dissipating layer or wavelength-selective absorbing layer) to make the laminate I, II, and pre-III into a filter exhibiting a specific absorption spectrum derived from the dye. This dispersion may be random, regular, or the like.

[0033] The light-absorbing and dissipating layer contains a compound that generates radicals upon ultraviolet irradiation dispersed (preferably dissolved) in the resin, which generates radicals upon ultraviolet irradiation. The generated radicals react with the dye, causing the dye to undergo a chemical change, thereby fading and decolorizing the dye. Furthermore, in the light-absorbing and dissipating layer constituting the laminate I and laminate pre-III, when the compound that generates radicals upon ultraviolet irradiation contains a compound A having an acid group and a compound B having a structure capable of forming a hydrogen bond with the acid group contained in compound A, as described below, the efficiency of generating radical species upon ultraviolet irradiation is improved compared to when a conventional photoradical generator such as a benzophenone compound is used. Therefore, even when ultraviolet irradiation is performed under mild temperature conditions such as room temperature, sufficient radical species are generated, and these radical species react directly or indirectly with the dye, causing the dye to decompose, resulting in fading and decolorization of the dye. In addition, in the light-absorbing and dissipating layer constituting the laminate I and laminate pre-III, when compound A having an acid group is bonded to the polymer constituting the resin contained in the light-absorbing and dissipating layer, radicals are generated near the dye by ultraviolet irradiation, and the radicals are more likely to react with the dye.Furthermore, the "compound B having a structure capable of forming a hydrogen bond with the acid group contained in compound A" described below forms a hydrogen bond with compound A and is dispersed (preferably dissolved) in the resin, or when compound A having an acid group is bonded to the polymer constituting the resin, it forms a hydrogen bond with compound A in the resin, and when irradiated with ultraviolet light, generates radicals, and the generated radicals react with the nearby dye, making the radicals more likely to react with the dye, and more efficiently fading and decolorizing the dye.The light-absorbing and dissipating layer constituting the laminate I and laminate pre-III will be described in detail below.

[0034] <<Light-Absorbing Disappearing Layer>> <Dye Having a Main Absorption Wavelength Band in a Wavelength Range of 400 to 700 nm> Specific examples of dyes having a main absorption wavelength band in a wavelength range of 400 to 700 nm and used in the light-absorbent disappearing layers that constitute the laminate I and the laminate pre-III include squaraine (SQ), cyanine (CY), benzylidene, cinnamylidene, azo, and indoaniline coloring materials (dyes).

[0035] Among these, the light-absorbing and dissipating layer preferably contains at least one of an azo dye represented by any one of general formulas (i) to (iv) below and an indoaniline dye represented by general formula (v) below, because these dyes are less likely to produce secondary colored structures due to dye decomposition. The azo dye represented by general formula (i) below is a dye having a main absorption wavelength band in the wavelength range of approximately 400 to 500 nm, the azo dye represented by any one of general formulas (ii) to (iv) below is a dye having a main absorption wavelength band in the wavelength range of approximately 450 to 650 nm, and the indoaniline dye represented by general formula (v) below is a dye having a main absorption wavelength band in the wavelength range of approximately 580 to 700 nm. When the light-absorbing and dissipating layer has such a configuration, it can exhibit excellent discoloration properties when irradiated with ultraviolet light.

[0036] The light-absorbing and disappearing layer may contain one or more of the azo dyes represented by the following general formula (i), the azo dyes represented by the following general formula (ii), the azo dyes represented by the following general formula (iii), the azo dyes represented by the following general formula (iv), and the indoaniline dyes represented by the following general formula (v). The light-absorbing and disappearing layer may contain a squaraine dye represented by general formula (1) described in the wavelength-selective absorption layer described below. The light-absorbing and disappearing layer may also contain dyes other than the azo dyes represented by any of the general formulas (i) to (iv), the indoaniline dyes represented by general formula (v), and the squaraine dye represented by general formula (1) described below. By optimizing the compounding ratio of the azo dye represented by any one of general formulas (i) to (iv) described below and the indoaniline dye represented by general formula (v) described below, in combination with a wavelength selective absorption layer described below, it is possible to suppress a change in the color of reflected light compared to when no dye is contained (hereinafter, also referred to as "adjusting the color of reflected light to be more neutral").

[0037] The light-absorbing and dissipating layer preferably contains a dye that absorbs in a wavelength region with lower absorbance than the main absorption wavelength bands of the dyes contained in the wavelength-selective-absorption layer described below, from the viewpoint of more easily achieving both suppression of external light reflection and suppression of brightness reduction. Specifically, the light-absorbing and dissipating layer preferably contains a dye having a main absorption wavelength band that is 5 nm or more away from any of the main absorption wavelength bands of the dyes contained in the wavelength-selective-absorption layer described below. In embodiments applied to OLED display devices, the "dye" contained in the light-absorbing and dissipating layer preferably contains at least one of the following dyes E to G, each of which has a main absorption wavelength band in a different wavelength region: Dye E: A dye having a main absorption wavelength band in a wavelength range of 430 to 480 nm, Dye F: A dye having a main absorption wavelength band in a wavelength range of 500 to 590 nm, Dye G: A dye having a main absorption wavelength band in a wavelength range of 600 to 660 nm. The light-absorbing and dissipating layer may contain one or more types of dye E. Similarly to dye E, dyes F and G that can be contained in the light-absorbing and dissipating layer may each independently be one type or two or more types. The wavelength range in which dye E has its main absorption wavelength band is preferably 430 to 475 nm, more preferably 430 to 470 nm, and even more preferably 430 to 465 nm. The wavelength range in which dye F has its main absorption wavelength band is preferably 505 to 585 nm, more preferably 510 to 580 nm, and even more preferably 515 to 580 nm. The wavelength range in which dye G has its main absorption wavelength band is preferably 610 to 655 nm, more preferably 610 to 650 nm, and even more preferably 610 to 640 nm. The light-absorbing and dissipating layer may also contain dyes other than dyes E to G.

[0038] In particular, from the viewpoint of combination with the wavelength-selective absorption layer described below, it is preferable that the dyes E, F, and G are a combination of at least two types, such as a combination containing at least dyes E and F and optionally dye G. Among these, it is preferable that the wavelength-selective absorption layer described below contain all of the dyes A to D described below, and the light-absorbing and disappearing layer contain at least two of the dyes E to G, from the viewpoints of achieving a higher level of suppression of external light reflection and suppression of brightness reduction in the light-transmitting and absorbing filters I and II, and of being able to adjust the color of reflected light to a neutral color when the obtained light-transmitting and absorbing filters I to II are applied to a display device. In relation to the dyes that may be contained in the wavelength-selective absorption layer described below, it is preferable that the main absorption wavelength band of the dye E is 5 to 70 nm (more preferably 5 to 60 nm) away from the main absorption wavelength band of the dye A described below, and 5 to 80 nm (more preferably 10 to 80 nm) away from the main absorption wavelength band of the dye B described below. In addition, when two or more wavelength-selective absorption layers are provided, the main absorption wavelength band of the dye E is preferably 1 to 70 nm (more preferably 1 to 60 nm) away from the main absorption wavelength band of the dye A described below, and 5 to 80 nm (more preferably 10 to 80 nm) away from the main absorption wavelength band of the dye B described below. Furthermore, the main absorption wavelength band of the dye F is preferably 5 to 80 nm (more preferably 10 to 80 nm) away from the main absorption wavelength band of the dye B described below, and 5 to 60 nm (more preferably 5 to 50 nm) away from the main absorption wavelength band of the dye C described below. Furthermore, the main absorption wavelength band of the dye G is preferably 5 to 60 nm (more preferably 10 to 50 nm) away from the main absorption wavelength band of the dye C described below, and 5 to 80 nm (more preferably 10 to 60 nm) away from the main absorption wavelength band of the dye D described below.

[0039] In the present invention, in the dyes represented by the following general formulas, the cations are delocalized and multiple tautomeric structures exist. Therefore, in the present invention, if at least one tautomeric structure of a dye corresponds to each general formula, the dye is considered to be a dye represented by that general formula. Therefore, a dye represented by a specific general formula can also be said to be a dye whose at least one tautomeric structure can be represented by a specific general formula. In the present invention, the dye represented by a general formula may have any tautomeric structure as long as at least one of its tautomeric structures corresponds to this general formula.

[0088] <Compound that generates radicals upon irradiation with ultraviolet rays> The light-absorbing and dissipative layer contains a compound that generates radicals upon irradiation with ultraviolet rays (also simply referred to as a "radical generator" in the present invention.) The radical generator is not particularly limited as long as it is a compound that generates radicals upon irradiation with ultraviolet rays and has the function of decolorizing the dye. For example, a photoradical generator that may be used in combination with compound B described below can be used as the radical generator.

[0089] The radical generator may be a combination of two or more compounds, preferably two or more of which interact with each other in the light-absorbing and dissipating layer, for example, to form complexes, thereby generating radicals upon UV irradiation. The types of compounds to be combined may be two or more compounds exhibiting different functions in the mechanism of generating radicals upon UV irradiation, preferably two types. A preferred example of such a combination is a combination of compound A having an acid group and compound B having a structure capable of forming a hydrogen bond with the acid group contained in compound A. When the light-absorbing and dissipating layer contains compound A having an acid group and compound B having a structure capable of forming a hydrogen bond with the acid group contained in compound A, the efficiency of generating radical species upon UV irradiation is improved compared to when the photoradical generator is used. Therefore, even when UV irradiation is performed under mild temperature conditions, such as room temperature, sufficient radical species are generated, and these radical species react directly or indirectly with the dye, causing the dye to decompose, resulting in fading and discoloration of the dye. In particular, the azo dyes represented by any one of the general formulas (i) to (iv), the indoaniline dyes represented by the general formula (v), and the squaraine dyes represented by the general formula (1) described below, which can be contained in the light-absorbing and dissipating layer, are discolored with almost no secondary absorption due to decomposition of the dye. Compound A having an acid group and compound B having a structure capable of forming a hydrogen bond with the acid group contained in compound A will be described in detail below.

[0090] (1) Compound A Having an Acid Group The light-absorbing and dissipating layer preferably contains, as the radical generator, Compound A having an acid group (also simply referred to as "Compound A" in the present invention), together with Compound B having a structure capable of forming a hydrogen bond with the acid group contained in Compound A, which will be described later.

Compound A may be a low-molecular-weight compound or a high-molecular-weight compound (hereinafter also referred to as a "polymer"), and is preferably a polymer.

Examples of the ethylenically unsaturated group include a (meth)acryloyl group, a vinyl group, and a styryl group, with a (meth)acryloyl group being preferred. When the ethylenically unsaturated group is a (meth)acryloyl group, the carbonyl bond in the (meth)acryloyl group and the carbonyl bond in the carboxy group may share one carbonyl bond. From the viewpoint of superior film-forming properties, the carboxy group-containing monomer is preferably a bifunctional or higher functional monomer containing a carboxy group. Note that a bifunctional or higher functional monomer refers to a polymerizable compound having two or more (e.g., 2 to 15) ethylenically unsaturated groups in one molecule. The number of carboxy groups contained in the carboxy group-containing monomer may be one or more, for example, preferably 1 to 8, more preferably 1 to 4, and even more preferably 1 to 2. The carboxyl group-containing monomer may further have an acid group other than a carboxyl group, such as a phenolic hydroxyl group, a phosphoric acid group, or a sulfonic acid group.

[0096] The difunctional or higher functional monomer containing a carboxy group is not particularly limited and can be appropriately selected from known compounds.

[0100] <<Constituent Unit Having Carboxy Group>> The carboxyl group-containing polymer preferably has a constituent unit having a carboxyl group. Examples of the constituent unit having a carboxyl group include constituent units derived from (meth)acrylic acid, crotonic acid, itaconic acid, maleic acid, or fumaric acid. Among these, constituent units derived from (meth)acrylic acid are preferred because of their excellent decolorization properties.

The structural unit having a carboxy group may be used alone or in combination of two or more types.

[0102] <Constituent Unit Having Aromatic Ring> In addition to the above-mentioned constituent units, the carboxyl group-containing polymer also preferably has a constituent unit having an aromatic ring (preferably an aromatic hydrocarbon ring). For example, a constituent unit derived from a (meth)acrylate having an aromatic ring (specifically, benzyl (meth)acrylate, phenethyl (meth)acrylate, phenoxyethyl (meth)acrylate, etc.) can be mentioned.

[0103] The content of the aromatic ring-containing structural unit in the carboxy group-containing polymer is preferably 0 to 97 mol %, more preferably 0 to 95 mol %, and even more preferably 0 to 90 mol %, when the total of all structural units in the carboxy group-containing polymer is taken as 100 mol %. The aromatic ring-containing structural unit may be used alone or in combination of two or more types.

The other structural units may be used alone or in combination of two or more.

[0107] (2) Compound B The light-absorbing and dissipative layer preferably contains, as the radical generator, compound B (also referred to simply as "compound B" in the present invention) having a structure capable of forming a hydrogen bond with the acid group contained in compound A, together with compound A. Compound B is preferably a compound having a structure that increases its basicity by absorbing ultraviolet light and becoming excited in an excited state. The increased basicity of compound B allows the acid group contained in compound A to form a complex with compound B through stronger interaction, thereby increasing the radical generation efficiency. The structure of compound B capable of forming a hydrogen bond with the acid group contained in compound A may be the entire structure of compound B or a partial structure constituting a part of compound B. Compound B may be a polymer compound (meaning a compound with a molecular weight of 5,000 or more) or a low molecular weight compound (meaning a compound with a molecular weight of less than 5,000), and is preferably a low molecular weight compound. The molecular weight of compound B, which is a low molecular weight compound, is less than 5,000, preferably less than 1,000, more preferably 500 or less, and even more preferably 350 or less. Although there is no particular limitation on the lower limit, it is preferably at least 65, and more preferably at least 75. A preferred range for the molecular weight of compound B, which is a low molecular weight compound, is, for example, at least 65 and less than 5,000, preferably at least 65 and less than 1,000, more preferably 65 to 500, and even more preferably 75 to 350.

[0108] Compound B is preferably an aromatic compound because it has a large molar absorption coefficient with respect to ultraviolet light. Here, an aromatic compound is a compound having one or more aromatic rings. Compound B may have only one aromatic ring or multiple aromatic rings. When multiple aromatic rings are present, for example, the aromatic rings may be present in a side chain of a polymer constituting the resin. The aromatic ring may be either an aromatic hydrocarbon ring or an aromatic heterocycle. In the case of an aromatic heterocycle (also referred to as a heteroaromatic ring), the compound has one or more (e.g., 1 to 4) heteroatoms (at least one of nitrogen atom, oxygen atom, sulfur atom, etc.) as ring-membering atoms (ring-constituting atoms), and preferably has one or more (e.g., 1 to 4) nitrogen atoms as ring-membering atoms. Note that unsubstituted aromatic hydrocarbons do not have a structure capable of forming hydrogen bonds with the acid groups contained in compound A, and therefore do not have the function of generating radicals upon ultraviolet irradiation, and therefore do not fall under compound B. Furthermore, the unsubstituted aromatic hydrocarbon ring in the form in which the unsubstituted aromatic hydrocarbon ring is bonded to the side chain of the polymer constituting the resin does not have a structure capable of forming a hydrogen bond with the acid group contained in compound A, and therefore does not have the function of generating radicals upon ultraviolet irradiation, and does not correspond to compound B. The number of ring-member atoms of the aromatic ring is preferably 5 to 15.

[0109] Examples of the aromatic ring include monocyclic aromatic rings such as a pyridine ring, a pyrazine ring, a pyrimidine ring, and a triazine ring; aromatic rings fused with two rings such as a quinoline ring, an isoquinoline ring, a quinoxaline ring, and a quinazoline ring; and aromatic rings fused with three rings such as an acridine ring, a phenanthridine ring, a phenanthroline ring, and a phenazine ring.

[0110] The aromatic ring may have one or more (e.g., 1 to 5) substituents, and examples of the substituents include an alkyl group, an aryl group, a halogen atom, an acyl group, an alkoxycarbonyl group, an arylcarbonyl group, a carbamoyl group, a hydroxy group, a cyano group, and a nitro group. Furthermore, when the aromatic ring has two or more substituents, the multiple substituents may be bonded to each other to form a non-aromatic ring. Note that when multiple aromatic rings (e.g., 2 to 5 aromatic rings) form a series of aromatic ring structures bonded by a structure selected from single bonds, carbonyl bonds, and multiple bonds (e.g., a vinylene group which may have a substituent, -C≡C-, -N=N-, etc.), the entire series of aromatic ring structures is considered to be one specific structure. The series of aromatic ring structures in which the above-mentioned multiple aromatic rings are bonded by a structure selected from a single bond, a carbonyl bond, and a multiple bond does not fall under the above-mentioned unsubstituted aromatic hydrocarbon ring, nor does it fall under the unsubstituted aromatic hydrocarbon ring in a form in which an unsubstituted aromatic hydrocarbon ring is bonded to a side chain of a polymer constituting a resin. In addition, it is preferable that one or more of the multiple aromatic rings constituting the series of aromatic ring structures is the above-mentioned heteroaromatic ring.

[0111] Specific examples of compound B include monocyclic aromatic compounds such as pyridine compounds (pyridine and pyridine derivatives), pyrazine compounds (pyrazine and pyrazine derivatives), pyrimidine compounds (pyrimidine and pyrimidine derivatives), and triazine compounds (triazine and triazine derivatives); compounds in which two rings are fused to form an aromatic ring, such as quinoline compounds (quinoline and quinoline derivatives), isoquinoline compounds (isoquinoline and isoquinoline derivatives), quinoxaline compounds (quinoxaline and quinoxaline derivatives), and quinazoline compounds (quinazoline and quinazoline derivatives); and compounds in which three or more rings are fused to form an aromatic ring, such as acridine compounds (acridine and acridine derivatives), phenanthridine compounds (phenanthridine and phenanthridine derivatives), phenanthroline compounds (phenanthroline and phenanthroline derivatives), and phenazine compounds (phenazine and phenazine derivatives). In these specific examples of compound B, the term "compound" refers not only to the compound itself, but also to compounds having a substituent (referred to as "derivatives"), including unsubstituted compounds whose structure has been partially modified to the extent that the effects of the present invention are not impaired. It is believed that these compounds B form complexes with the aforementioned compound A, and generate two radical molecules through the following mechanism when irradiated with ultraviolet light: 1) Compound B in an excited state is generated by absorbing ultraviolet light; 2) A hole moves from excited compound B to compound A in the ground state (an electron from compound A moves to the lower-energy orbital of the two half-occupied orbitals of excited compound B); 3) A proton moves from compound A to compound B, generating a radical in which a hydrogen radical is added to compound B and a radical in which a hydrogen radical is released from compound A. When compound A is a compound having a carboxyl group, the following reaction further occurs, generating a radical by photodecarboxylation: 4) Carbon dioxide is released from the radical resulting from the release of a hydrogen radical from compound A.

[0112] Among these, compound B is preferably one or more of quinoline compounds (quinoline and quinoline derivatives) and isoquinoline compounds (isoquinoline and isoquinoline derivatives). Preferred substituents that these compounds may have are alkyl groups, aryl groups, halogen atoms, acyl groups, alkoxycarbonyl groups, arylcarbonyl groups, carbamoyl groups, hydroxy groups, cyano groups, and nitro groups.

[0113] When compound B is a polymer, the specific structure may be bonded to the polymer main chain via a single bond or a linking group. Compound B, which is a polymer, can be obtained, for example, by polymerizing a monomer having a heteroaromatic ring (specifically, a heteroaromatic ring having a vinyl group and / or a (meth)acrylate monomer having a heteroaromatic ring). If necessary, compound B may be copolymerized with other monomers.

[0114] Specific examples of compound B include quinoline, 2-methylquinoline, 4-methylquinoline, 2,4-dimethylquinoline, 2-methyl-4-phenylquinoline, isoquinoline, 1-methylisoquinoline, 3-methylisoquinoline, and 1-phenylisoquinoline.

[0115] From the viewpoint of achieving both the decolorization property of the UV-irradiated portion and the durability of the dye in the UV-unirradiated portion, the content of compound B is preferably 0.1 to 50% by mass, more preferably 2.0 to 40% by mass, even more preferably 4 to 35% by mass, and particularly preferably 8 to 30% by mass, relative to the total mass of the light-absorption-disappearing layer. Similarly, from the viewpoint of achieving both the decolorization property of the UV-irradiated portion and the durability of the dye in the UV-unirradiated portion, the pKaH (pKa of the conjugate acid), which is a measure of the basicity of compound B, is preferably 2.0 to 7.0, more preferably 3.0 to 6.0, and even more preferably 4.3 to 5.5. In the present invention, pKa refers to the negative common logarithm (−logKa) of the acid dissociation constant (Ka) in a mixed solvent of water / methanol = 50 / 50 (volume ratio) at 25°C. The pKa can be calculated by adding 0.01 mol / L of aqueous sodium hydroxide solution dropwise to a 50 / 50 (volume ratio) water / methanol mixed solution of a measurement sample (conjugate acid of compound B) and reading the amount of aqueous sodium hydroxide added dropwise up to the half-equivalent point. Compound B may be used singly or in combination of two or more types.

[0116] <Resin> The resin contained in the light-absorbing and disappearing layer is not particularly limited, as long as it can disperse (preferably dissolve) the dye, can cause the dye to fade due to radicals generated from a compound that generates radicals upon irradiation with ultraviolet light (preferably a radical generator containing compound B hydrogen-bonded to an acid group contained in compound A), and has desired light transmittance (a light transmittance of 80% or more is preferred in the visible region of a wavelength of 400 to 800 nm).

[0117] Various polymers can be used as the polymer constituting the resin. From the viewpoint of preventing the molecular weight of the resin from decreasing due to ultraviolet irradiation, polymers having an aromatic ring or alicyclic structure in the side chain are preferred, and chain polymerization polymers such as (meth)acrylic polymers containing structural units having an aromatic ring or alicyclic structure are more preferred. Among them, from the viewpoint of further improving the decolorization rate and further improving heat resistance and light resistance, (meth)acrylic polymers containing structural units having an alicyclic structure are even more preferred. Here, (meth)acrylic polymer refers to a polymer containing at least one structural unit derived from (meth)acrylic acid and a structural unit derived from a (meth)acrylic acid ester. Note that when the polymer contains a structural unit derived from (meth)acrylic acid, the structural unit derived from (meth)acrylic acid becomes a structural unit having a carboxy group as the acid group in the above-mentioned compound A, and corresponds to the above-mentioned polymer in which the above-mentioned compound A is chemically bonded to the polymer constituting the resin. In addition, in the present invention, the "main chain" refers to the relatively longest bonded chain in the molecule of the polymer compound, and the "side chain" refers to an atomic group branched from the main chain.

[0118] Examples of monomers that derive structural units having an aromatic ring include (meth)acrylates having an aromatic ring, such as benzyl acrylate, benzyl methacrylate, naphthyl acrylate, naphthyl methacrylate, naphthyl methyl acrylate, and naphthyl methyl methacrylate. When the polymer does not contain a structural unit derived from (meth)acrylic acid, the content of the structural unit having an aromatic ring is preferably 5 to 100% by mass, more preferably 10 to 100% by mass, and even more preferably 20 to 100% by mass, relative to the total mass of the polymer.

[0119] Examples of monomers that derive structural units having an alicyclic structure include dicyclopentanyl (meth)acrylate, cyclohexyl (meth)acrylate, isobornyl (meth)acrylate, and adamantyl (meth)acrylate. When the polymer contains structural units having an alicyclic structure, the content of the structural units having an alicyclic structure is preferably 1 to 90% by mass, more preferably 5 to 90% by mass, and even more preferably 5 to 80% by mass, relative to the total mass of the polymer.

[0120] Furthermore, in the light-absorbing and dissipative layer, the polymer constituting the resin may contain a structural unit bonded to a compound A having an acid group. The structural unit bonded to a compound A having an acid group can be the same as the structural unit having a carboxy group described above for compound A, with a structural unit derived from (meth)acrylic acid being preferred. The content of the structural unit bonded to a compound A having an acid group (preferably a structural unit derived from (meth)acrylic acid) is preferably 1 to 70% by mass, more preferably 1 to 60% by mass, relative to the total mass of the polymer. More preferably, the description of the content of the structural unit having a carboxy group in the carboxy group-containing polymer of compound A described above applies. When the polymer constituting the resin contains a structural unit bonded to a compound A having an acid group, the content of the structural unit having an aromatic ring, and the content of the structural unit having an alicyclic structure in the carboxy group-containing polymer of compound A described above apply to the content of the structural unit bonded to a compound A having an acid group, the content of the structural unit having an aromatic ring, and the content of the structural unit having an alicyclic structure.

[0121] The polymer constituting the resin may contain a structural unit having an alkyl group having 1 to 14 carbon atoms from the viewpoint of adjusting the glass transition temperature, etc. Examples of structural units having an alkyl group having 1 to 14 carbon atoms include structural units derived from alkyl (meth)acrylates such as methyl (meth)acrylate, ethyl (meth)acrylate, n-propyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate, t-butyl (meth)acrylate, sec-butyl (meth)acrylate, pentyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, 2-ethylbutyl (meth)acrylate, n-octyl (meth)acrylate, isooctyl (meth)acrylate, isononyl (meth)acrylate, lauryl (meth)acrylate, and tetradecyl (meth)acrylate. In the present invention, structural units having an alkyl group having 1 to 14 carbon atoms may be used alone, or two or more types may be used in combination. The content of the structural unit having an alkyl group having 1 to 14 carbon atoms is preferably 0 to 95% by mass relative to the total mass of the polymers constituting the resin.

[0122] The weight average molecular weight (Mw) of the polymer constituting the resin is preferably 10,000 or more, more preferably 10,000 to 200,000, and even more preferably 15,000 to 150,000.

[0123] Next, the wavelength selective absorption layers constituting the laminate I and laminate II will be described in detail.

[0124] <<Wavelength-Selective Absorption Layer>> The wavelength-selective absorption layer constituting Laminate I and Laminate II contains a resin and a dye having a main absorption wavelength band in the wavelength range of 400 to 700 nm, and does not contain a compound that generates radicals upon ultraviolet irradiation. The "dye" preferably does not have a main absorption wavelength band at any of the wavelengths of 460 nm, 530 nm, and 620 nm, and more preferably does not have a main absorption wavelength band at any of the wavelength ranges of 450 to 470 nm, greater than 520 nm but not greater than 540 nm, or greater than 610 nm but not greater than 630 nm. In the wavelength-selective absorption layer, the "dye" is dispersed (preferably dissolved) in the resin, thereby making the wavelength-selective absorption layer a layer that exhibits a specific absorption spectrum derived from the dye.

[0125] <Dye> The "dye" contained in the wavelength-selective absorption layer preferably includes at least one of the following dyes A to D, which have a main absorption wavelength band in a different wavelength range. Dye A: A dye having a main absorption wavelength band in a wavelength range of 390 to 435 nm Dye B: A dye having a main absorption wavelength band in a wavelength range of 480 to 520 nm Dye C: A dye having a main absorption wavelength band in a wavelength range of 560 to 610 nm Dye D: A dye having a main absorption wavelength band in a wavelength range of 640 to 780 nm The dye A that can be contained in the wavelength-selective absorption layer may be one type or two or more types. As with dye A, the dyes B to D that can be contained in the wavelength-selective absorption layer may each independently be one type or two or more types. The wavelength-selective absorption layer may also contain dyes other than dyes A to D.

[0126] The wavelength-selective absorption layer may have any form as long as the dye in the wavelength-selective absorption layer exhibits an absorption spectrum, and in combination with the light-absorbing and disappearing layer, the resulting light-transmitting and absorbing filters I and II can simultaneously suppress external light reflection and brightness reduction, and preferably does not affect the original color of the displayed image. One form of the wavelength-selective absorption layer is one in which a dye (preferably at least one of dyes A to D) is dispersed (preferably dissolved) in a resin. This dispersion may be random, regular, or the like.

[0127] In the wavelength-selective absorption layer, the dyes A to D have main absorption wavelength bands in the wavelength ranges of 390 to 435 nm, 480 to 520 nm, 560 to 610 nm, and 640 to 780 nm, which do not overlap with the wavelength ranges of B (Blue, 460 nm), G (Green, 530 nm), and R (Red, 620 nm), which are used as light-emitting sources in OLED display devices. Therefore, by containing at least one of these dyes A to D, the wavelength-selective absorption layer can suppress reflection of external light in the light-emitting section of the display device without impairing the color reproduction range of light emitted from the OLED display element.

[0128] In particular, from the viewpoint of using a wavelength-selective absorption layer that exhibits an absorption spectrum that has a negative correlation with the emission spectrum of the light-emitting source and bringing out the original color of an image in an OLED display device, it is preferable that the dyes A, B, C, and D contained in the wavelength-selective absorption layer are a combination of at least two types, more preferably a combination of at least three types, and even more preferably all four types are contained. When two or more types of dyes A to D are contained in the wavelength-selective absorption layer as described above, a problem of reduced lightfastness due to mixing of the dyes may occur due to chain transfer of radicals generated during dye decomposition, etc. To address this problem, the wavelength-selective absorption layer in the laminate I and laminate II, as well as the light-transmitting-absorption filter I obtained by mask exposure of the laminate I, and the light-transmitting-absorption filter II containing the laminate II and laminate III, can exhibit an excellent level of lightfastness that overcomes the reduced lightfastness that accompanies mixing of the dyes, by providing a specific gas barrier layer as described below or by having multiple dyes separated into two wavelength-selective absorption layers.

[0129] In particular, from the viewpoint of further bringing out the original color of an image of an OLED display device, it is preferable that the wavelength-selective-absorption layer contains all of the four dyes A to D and satisfies the following relational formulas (I) to (VI): Light-transmission-absorption filter I obtained from laminate I having a wavelength-selective-absorption layer with such a configuration and the above-mentioned light-absorbing-disappearing layer, and light-transmission-absorption filter II obtained from laminate II and laminate III including a wavelength-selective-absorption layer with such a configuration, can not only satisfactorily suppress external light reflection and brightness reduction, but also maintain the original color of an image of an OLED display device at an excellent level. Relational formula (I) Ab(450) / Ab(430)<1.0 Relational formula (II) Ab(450) / Ab(500)<1.0 Relational formula (III) Ab(540) / Ab(500)<1.0 Relational formula (IV) Ab(540) / Ab(600)<1.0 Relational formula (V) Ab(630) / Ab(600)≦0.5 Relational formula (VI) Ab(630) / Ab(700)<1.0

[0130] In the ranges defined by the above relational formulas (I) to (VI), preferred ranges are as follows: The upper limit of Ab(450) / Ab(430) in relational formula (I) is preferably 0.90 or less, more preferably 0.85 or less, even more preferably 0.80 or less, and particularly preferably 0.60 or less. There is no particular restriction on the lower limit, but a practical value is 0.05 or more, preferably 0.10 or more, and more preferably 0.20 or more. The upper limit of Ab(450) / Ab(500) in relational formula (II) is preferably 0.90 or less, more preferably 0.80 or less, even more preferably 0.75 or less, particularly preferably 0.65 or less, and of these, 0.60 or less is preferred, and 0.50 or less is most preferred. There is no particular restriction on the lower limit, but a practical value is 0.05 or more, preferably 0.10 or more, and more preferably 0.20 or more. The upper limit of Ab(540) / Ab(500) in the relational formula (III) is preferably 0.90 or less, more preferably 0.80 or less, even more preferably 0.75 or less, particularly preferably 0.70 or less, and of these, 0.50 or less is preferred, and 0.20 or less is most preferred. There is no particular restriction on the lower limit, but 0.01 or more is practical, 0.02 or more is preferred, and 0.05 or more is more preferred. The upper limit of Ab(540) / Ab(600) in the relational formula (IV) is preferably 0.90 or less, more preferably 0.85 or less, even more preferably 0.80 or less, particularly preferably 0.70 or less, and of these, 0.50 or less is preferred, and 0.25 or less is most preferred. There is no particular restriction on the lower limit, but 0.01 or more is practical, 0.02 or more is preferred, and 0.05 or more is more preferred. The upper limit of Ab(630) / Ab(600) in relational formula (V) is preferably 0.40 or less, more preferably 0.30 or less, even more preferably 0.20 or less, and particularly preferably 0.15 or less. There is no particular restriction on the lower limit, but a practical value is 0.01 or more, preferably 0.02 or more, and more preferably 0.05 or more. The upper limit of Ab(630) / Ab(700) in relational formula (VI) is preferably 0.95 or less, more preferably 0.90 or less, even more preferably 0.80 or less, and particularly preferably 0.75 or less.There is no particular restriction on the lower limit, but a practical value is 0.01 or more, preferably 0.03 or more, more preferably 0.10 or more, even more preferably 0.40 or more, and particularly preferably 0.50 or more.

[0131] By satisfying the above-described preferred ranges for each of the relational expressions (I) to (VI), it is possible to minimize the color change caused by the provision of the light-transmitting / absorbing filters I to II, thereby enabling the original color of the image produced by the OLED display device to be more clearly displayed. Therefore, it is preferable that the dyes A to D have a sharp absorption waveform in the main absorption wavelength band. For example, when dye B is a squaraine dye represented by the general formula (1) described below, the wavelength-selective / absorbent layer can satisfy the above-described preferred ranges for relational expressions (II) and (III), thereby enabling the original color of the image produced by the OLED display device to be more clearly displayed. This is thought to be due to the low absorbance at wavelengths near the absorption maximum (534 nm) of the green visual pigment in human cones. Furthermore, when dye C is a squaraine dye represented by the general formula (1) described below, the wavelength-selective / absorbent layer can satisfy the above-described preferred ranges for relational expressions (I) to (IV), thereby enabling the original color of the image produced by the OLED display device to be more clearly displayed. This is also thought to be due to the low absorbance at wavelengths near the absorption maximum (534 nm) of the green visual pigment in human cones, as mentioned above. In particular, satisfying the relational expression (V) is important in that it does not affect the original color of the image of the OLED display device. According to the relational expression (V), a ＊ It is believed that this can suppress the change in color tone, and as a result, the above-mentioned color tone can be maintained at an excellent level.

[0132] The wavelength-selective absorption layer of Laminate I and Laminate II may be a single layer, or may be a two-layer structure from the viewpoint of suppressing a decrease in light resistance due to the mixing of the above-mentioned dyes. When the wavelength-selective absorption layer has a two-layer structure consisting of a first wavelength-selective absorption layer and a second wavelength-selective absorption layer, it is preferable that the dye contained in the first wavelength-selective absorption layer has a main absorption wavelength band in a wavelength range different from that of the dye contained in the second wavelength-selective absorption layer. Note that, "the dye contained in the first wavelength-selective absorption layer has a main absorption wavelength band in a wavelength range different from that of the dye contained in the second wavelength-selective absorption layer" means that the maximum absorption maximum wavelength of the dye contained in the first wavelength-selective absorption layer and the maximum absorption maximum wavelength of the dye contained in the second wavelength-selective absorption layer are separated by 50 nm or more. In particular, when the laminate I and the laminate II are used by being arranged in a display device such that the first-wavelength-selective-absorption layer side faces the external light side (the viewer side) and the second-wavelength-selective-absorption layer side faces the display device, it is preferable that the first-wavelength-selective-absorption layer contains a dye having a main absorption wavelength band on the shortest wavelength side (hereinafter referred to as "shortest-wavelength dye") among the dyes contained in the first-wavelength-selective-absorption layer and the second-wavelength-selective-absorption layer. When the first-wavelength-selective-absorption layer located on the external light side contains the shortest-wavelength dye, photodecomposition of dyes other than the shortest-wavelength dye due to photoexcitation of the shortest-wavelength dye can be more effectively suppressed, and excellent lightfastness can be exhibited.

[0133] The combination of the dye contained in the first wavelength selective absorption layer and the dye contained in the second wavelength selective absorption layer is preferably one that can both suppress a decrease in brightness and suppress the influence of reflected color when the light transmission / absorption filter of the present invention is applied to a display device. It is preferable that the first wavelength selective absorption layer and the second wavelength selective absorption layer each contain at least one dye having a main absorption wavelength band in a different wavelength range. The first wavelength selective absorption layer may contain two or more dyes with different main absorption wavelength bands, and the second wavelength selective absorption layer may contain two or more dyes with different main absorption wavelength bands. Even when at least one of the first wavelength selective absorption layer and the second wavelength selective absorption layer contains two or more dyes with different main absorption wavelength bands, it is preferable that the dye contained in the first wavelength selective absorption layer and the dye contained in the second wavelength selective absorption layer have main absorption wavelength bands in different wavelength ranges. The first wavelength selective absorption layer containing two or more dyes with different main absorption wavelength bands means that the maximum absorption wavelengths of the two or more dyes contained in the first wavelength selective absorption layer are separated by 50 nm or more. Furthermore, the second wavelength selective absorption layer containing two or more dyes with different main absorption wavelength bands means that the maximum absorption wavelengths of the two or more dyes contained in the second wavelength selective absorption layer are separated by 50 nm or more. Of these, the shortest wavelength dye is preferably contained in the first wavelength selective absorption layer, as described above, and the shortest wavelength dye is preferably dye A described above.

[0134] The "dye" contained in the first wavelength selective absorption layer and the second wavelength selective absorption layer can be described in the same manner as in the "dye" above, and preferably contains at least one of the dyes A to D. The dyes A to D that can be contained in two or more wavelength selective absorption layers may each independently be one type or two or more types. In particular, it is preferable that the dye contained in the first wavelength selective absorption layer and the dye contained in the second wavelength selective absorption layer are combined to contain all of the dyes A to D. A preferred example of such a configuration is one in which the first wavelength selective absorption layer contains the dyes A and C, and the second wavelength selective absorption layer contains the dyes B and D. Furthermore, with regard to the above relational formulas (I) to (VI), it is preferable that the first wavelength selective absorption layer and the second wavelength selective absorption layer alone do not satisfy all of the above relational formulas (I) to (VI), but that the wavelength selective absorption layer as a whole, including the first wavelength selective absorption layer and the second wavelength selective absorption layer, satisfies all of the above relational formulas (I) to (VI).

[0135] (Dye A) Dye A is not particularly limited as long as it has a main absorption wavelength band in the wavelength range of 390 to 435 nm in Laminate I and Laminate II, and various dyes can be used. The wavelength range in which dye A has a main absorption wavelength band is preferably 395 to 435 nm, more preferably 400 to 435 nm, and even more preferably 405 to 435 nm. Specific examples of dye A include porphyrin-based, squaraine-based, cyanine (CY)-based, pyrrole methine-based, and indoaniline-based pigments (dyes).

The content of dye C in the wavelength selective absorption layer is preferably 0.01 to 30% by mass, and more preferably 0.1 to 10% by mass. The content of dye D in the wavelength selective absorption layer is preferably 0.05 to 45% by mass, and more preferably 0.1 to 30% by mass. When the laminate I and the laminate II have the first wavelength selective absorption layer and the second wavelength selective absorption layer described above, the description of the contents of each of the dyes A to D that can be contained in the wavelength selective absorption layer applies to each of the first wavelength selective absorption layer and the second wavelength selective absorption layer.

[0237] When the wavelength selective absorption layer contains all four types of dyes A to D, the content ratio of each of the dyes A to D in the wavelength selective absorption layer is, in mass ratio, preferably dye A:dye B:dye C:dye D=1 to 50:0.1 to 10:1:0.1 to 20, and more preferably 1 to 40:0.2 to 10:1:0.2 to 15. When the laminate I and the laminate II have the above-mentioned first wavelength selective absorption layer and second wavelength selective absorption layer, the description of the content ratio of each of the dyes A to D in the wavelength selective absorption layer applies to the content ratio of each of the dyes A to D as a whole of the dyes contained in the first wavelength selective absorption layer and the second wavelength selective absorption layer.

[0238] In addition, when at least one of dyes B and C is the above-mentioned quencher-containing dye, the content of the above-mentioned quencher-containing dye is preferably 0.1 to 45% by mass relative to 100% by mass of the wavelength-selective absorption layer in terms of anti-reflection effect.

[0239] <Resin> The resin (hereinafter also referred to as "matrix resin") contained in the wavelength selective absorption layer is not particularly limited as long as it can disperse (preferably dissolve) the dye. Among these, a resin that can satisfactorily suppress external light reflection and brightness reduction, while also maintaining the original color of the image of the OLED display device at an excellent level, is preferred. When at least one of dyes B and C is a squaraine dye represented by the above-mentioned general formula (1), the matrix resin is preferably a low-polarity matrix resin that allows this squaraine dye to exhibit a sharper absorption peak. By the squaraine dye exhibiting a sharper absorption peak, the above-mentioned relational expressions (I) to (VI) can be satisfied at a preferred level, and the original color of the image of the OLED display device can be maintained at an excellent level. Here, low polarity preferably means that the fd value defined by the following relational expression I is 0.50 or more. Relational formula I: fd = δd / (δd + δp + δh) In Relational formula I, δd, δp, and δh respectively represent a term corresponding to the London dispersion force, a term corresponding to the dipole-dipole force, and a term corresponding to the hydrogen bonding force, relative to the solubility parameter δt calculated by the Hoy method. A specific calculation method will be described later. That is, fd represents the ratio of δd to the sum of δd, δp, and δh. By setting the fd value to 0.50 or more, it becomes easier to obtain a sharper absorption waveform. Furthermore, when the wavelength selective absorption layer contains two or more types of matrix resins, the fd value is calculated as follows: fd = Σ(w ｉ ・fd ｉ ) where w ｉ is the mass fraction of the i-th matrix resin, fd ｉ indicates the fd value of the i-th matrix resin.

[0240] - The term δd corresponding to the London dispersion force - The term δd corresponding to the London dispersion force is described in the literature "Properties of Polymers 3 ｒｄ , ELSEVIER, (1990) pages 214-220, column "2) Method of Hoy (1985, 1989)" and is calculated according to the description in the above column of the above document.

[0241] - The term δp corresponding to the dipole-dipole force - The term δp corresponding to the dipole-dipole force is described in the literature "Properties of Polymers 3 ｒｄ , ELSEVIER, (1990) pp. 214-220, column "2) Method of Hoy (1985, 1989)" and is calculated according to the description in the above column of the above document.

[0243] Furthermore, if the matrix resin is a resin exhibiting a certain degree of hydrophobicity, the moisture content of the wavelength-selective absorption layer can be reduced to a low moisture content of, for example, 0.5% or less, which is preferable from the viewpoint of improving the light resistance of the laminate I (excluding the light-absorbing and disappearing layer) and laminate II containing the wavelength-selective absorption layer. The resin may contain any conventional component in addition to the polymer. However, the fd of the matrix resin is a calculated value for the polymer constituting the matrix resin.

[0244] Preferred examples of the matrix resin include polystyrene resin and cyclic polyolefin resin, with polystyrene resin being more preferred. Typically, the fd value of polystyrene resin is 0.45 to 0.60, and the fd value of cyclic polyolefin resin is 0.45 to 0.70. As mentioned above, it is preferable to use a resin with an fd value of 0.50 or greater. In addition to these preferred resins, it is also preferable to use resin components that impart functionality to the wavelength-selective absorption layer, such as the extensible resin component and release-controlling resin component described below. That is, in the present invention, the term "matrix resin" is used to include the extensible resin component and release-controlling resin component in addition to the resins described above.

[0246] The wavelength-selective absorption layer preferably contains a polyphenylene ether resin in addition to the polystyrene resin. By incorporating both a polystyrene resin and a polyphenylene ether resin, the toughness of the wavelength-selective absorption layer can be improved, and the occurrence of defects such as cracks can be suppressed even in harsh environments such as high temperature and high humidity. Examples of the polyphenylene ether resin include Zylon S201A, S202A, and S203A (all trade names) manufactured by Asahi Kasei Corporation.

[0257] (Extensible Resin Component) The wavelength selective absorption layer can contain an appropriately selected component exhibiting extensibility (also referred to as an extensible resin component) as a resin component. Specific examples include acrylonitrile-butadiene-styrene resin (ABS resin), styrene-butadiene resin (SB resin), isoprene resin, butadiene resin, polyether-urethane resin, and silicone resin. These resins may also be hydrogenated as appropriate. As the extensible resin component, it is preferable to use an ABS resin or an SB resin, and it is more preferable to use an SB resin.

[0259] The wavelength selective absorption layer preferably contains 15 to 95% by mass, more preferably 20 to 50% by mass, and even more preferably 25 to 45% by mass of the extensible resin component in the matrix resin.

[0261] <Adhesion Improver> When a gas barrier layer is present as a layer adjacent to the wavelength selective absorption layer, the wavelength selective absorption layer preferably contains an adhesion improver to improve adhesion to the gas barrier layer. The structure of the adhesion improver is not particularly limited as long as adhesion to the gas barrier layer is obtained. For example, when the gas barrier layer contains polyvinyl alcohol as a forming material, the adhesion improver preferably has a structure that bonds with the hydroxyl group of the polyvinyl alcohol, more preferably a polymer having a boronic acid-containing group, and even more preferably a polymer containing a structural unit having a boronic acid-containing group. Specifically, the description of the copolymer (a) described in paragraphs

[0022] to

[0083] of Japanese Patent No. 6722602 can be applied as is as the polymer having a boronic acid-containing group. The boronic acid-containing group refers to a group such as -B(OH) ２ and is not limited to the group represented by -B(OR １１ ) (OR １２ ) (wherein R １１ and R １２and (may be linked). When the wavelength-selective absorption layer contains a polymer having a boronic acid-containing group, the boronic acid-containing polymer contained in the wavelength-selective absorption layer is unevenly distributed at the interface between the wavelength-selective absorption layer and the gas barrier layer, and the -B-OH in the boronic acid-containing group forms a chemical bond such as a boronic acid ester with a hydrophilic group such as an -OH group in the gas barrier layer, thereby improving adhesion. Note that the boronic acid-containing polymer is not included in the polymer constituting the transparent resin in the wavelength-selective absorption layer. Here, the presence of a boronic acid-containing group at the interface between the wavelength-selective absorption layer and the gas barrier layer, or the formation of a chemical bond such as a boronic acid ester with a hydrophilic group such as an -OH group in the gas barrier layer, can be confirmed by, for example, time-of-flight secondary ion mass spectrometry (TOF-SIMS). Note that the TOF-SIMS method described in "Surface Analysis Technology Selection: Secondary Ion Mass Spectrometry" edited by the Japan Surface Science Society, published by Maruzen Co., Ltd. (1999), can be used. Specifically, fragments derived from chemical bonds such as boronic acid-containing groups or boronic acid esters formed between the boronic acid-containing groups and hydrophilic groups such as -OH groups in the gas barrier layer are detected. In the present invention, the phrase "the wavelength-selective absorption layer further contains a polymer having a boronic acid-containing group" includes not only an embodiment in which the wavelength-selective absorption layer contains a polymer having a boronic acid-containing group, but also an embodiment in which the boronic acid-containing group of the polymer having the boronic acid-containing group is used to form a chemical bond with a hydrophilic group such as an -OH group in the gas barrier layer.

[0262] In addition, acid-modified resins such as the "Tuftec M series" manufactured by Asahi Kasei Chemicals Corporation, the "Admer series" and "Unistall series" manufactured by Mitsui Chemicals, Inc., the "Umex series" manufactured by Sanyo Chemical Industries, Ltd., and the "Hardlen series" manufactured by Toyobo Co., Ltd. can also be preferably used as adhesion improvers to be added to the wavelength-selective absorption layer.

[0263] The content of the adhesion promoter in the wavelength selective absorption layer is, for example, preferably from 0.1 to 15% by mass, more preferably from 0.3 to 13% by mass, and even more preferably from 0.5 to 10% by mass.

[0264] <Other Components> The light-absorbing and dissipating layer and wavelength-selective absorption layer of the present invention may contain a leveling agent (surfactant) and the like in addition to the above-mentioned components (dye, resin, and in the light-absorbing and dissipating layer, further a radical generator).

[0265] (Leveling Agent) The light-absorbing and dissipating layer and the wavelength-selective absorption layer may each appropriately contain a leveling agent (surfactant). Commonly used compounds can be used as the leveling agent, with fluorine-containing surfactants being particularly preferred. Specific examples include the compounds described in paragraphs

[0028] to

[0056] of JP-A No. 2001-330725. Furthermore, commercially available products such as the Megafac F (trade name) series manufactured by DIC Corporation may also be used. The content of the leveling agent in the light-absorbing and dissipating layer or the wavelength-selective absorption layer is appropriately adjusted depending on the purpose.

[0266] The light-absorbing and dissipating layer and the wavelength-selective absorption layer may each contain, in addition to the above components, a low-molecular-weight plasticizer, an oligomer-based plasticizer, a retardation adjuster, an ultraviolet absorber, a deterioration inhibitor, a peeling promoter, an infrared absorber, an antioxidant, a filler, a compatibilizer, and the like.

[0267] (Matting Agent) Fine particles may be added to the surface of the laminate I, and the laminates of the laminate II and laminate pre-III to impart slip properties and prevent blocking. These fine particles may be silica (silicon dioxide, SiO ) whose surface is coated with hydrophobic groups and in the form of secondary particles. ２ ) is preferably used. As the fine particles, fine particles such as titanium dioxide, aluminum oxide, zirconium oxide, calcium carbonate, talc, clay, calcined kaolin, calcined calcium silicate, hydrated calcium silicate, aluminum silicate, magnesium silicate, and calcium phosphate may be used together with or instead of silica. Examples of commercially available fine particles include R972 and NX90S (both manufactured by Nippon Aerosil Co., Ltd., trade names).

[0268] These fine particles function as a so-called matting agent, and by adding the fine particles, minute irregularities are formed on the surface of the laminate I and the laminate of the laminate II and the laminate pre-III, and these irregularities prevent the laminate I from sticking together, the laminate II and the laminate pre-III, or the laminate I and other films, or the laminate II and the laminate pre-III and other films, etc., even when they are stacked, and ensure smoothness.When the laminate I and the laminate II and the laminate pre-III contain a matting agent as fine particles, the minute irregularities caused by the protrusions of the fine particles protruding from the filter surface have protrusions of 30 nm or more in height in 10 ４ pieces / mm ２ When the above amount is present, the effect of improving the slipperiness and blocking properties is particularly great.

[0269] Methods for applying fine particles to the surface layer of the laminate I and the laminate of the laminate II and the laminate pre-III include multilayer casting and coating. The content of the matting agent in the laminate I and the laminate of the laminate II and the laminate pre-III is appropriately adjusted depending on the purpose. The matting agent (fine particles) added to the surface of the laminate I (also referred to as application to the surface layer) also remains on the surface of the light transmission-absorption filter I obtained using the laminate I, and can prevent the light transmission-absorption filters I, or the light transmission-absorption filter I and other films, from sticking to each other when they are overlapped. This also applies to the laminate of the laminate II and the laminate pre-III, and can prevent the light transmission-absorption filters II, or the light transmission-absorption filter II and other films, from sticking to each other when they are overlapped. It is also preferable to apply the matting agent to the surface layer of the light transmission-absorption filter of the present invention from the same viewpoint as the laminate I and the laminate of the laminate II and the laminate pre-III.

[0270] <Manufacturing Method of Laminate I, Laminate II, and Laminate Pre-III> (Manufacturing Method of Light-Absorbing and Dissipating Layer and Wavelength-Selective Absorbing Layer) The light-absorbing and dissipating layer in Laminate I and Laminate Pre-III and the wavelength-selective absorbing layer in Laminate I and Laminate II can be manufactured by a conventional method, such as a solution film-forming method, a melt extrusion method, or a method of forming a coating layer on a substrate film (support film) by any method (coating method), and stretching can also be combined as appropriate. The light-absorbing and dissipating layer and wavelength-selective absorbing layer are preferably manufactured by a coating method. As the solution film-forming method and melt extrusion method, the descriptions of the solution film-forming method and melt extrusion method in paragraphs

[0197] to

[0203] of WO 2021 / 132674 can be applied as they are, except that "light-absorbing filter" is replaced with "light-absorbing and dissipating layer" or "wavelength-selective absorbing layer".

[0271] (Coating Method) In the coating method, a solution of the material of the light-absorbing and disappearing layer or the wavelength-selective absorption layer is applied to a support film to form a coating layer. A release agent or the like may be applied in advance to the surface of the support film as appropriate to control adhesion to the coating layer. The coating layer may also be formed on the support film via an optional resin layer. The coating layer can be used by laminating it to another member via an adhesive layer in a subsequent process and then peeling off the support film. Any adhesive can be used as the adhesive constituting the adhesive layer. The support film can be stretched as appropriate with the solution of the material of the light-absorbing and disappearing layer or the wavelength-selective absorption layer applied to it or with the coating layer laminated on it.

[0272] The solvent used in the solution of the material for the light-absorbing and disappearing layer or the wavelength-selective absorption layer can be appropriately selected from the viewpoints of being able to dissolve or disperse the material for the light-absorbing and disappearing layer or the wavelength-selective absorption layer, being able to easily form a uniform surface in the coating and drying steps, being able to ensure the storage stability of the liquid, having an appropriate saturated vapor pressure, etc.

[0273] -Addition of Components Constituting the Light-Absorbing and Disappearing Layer or the Wavelength-Selective Absorption Layer- The timing of adding the dye and the radical generator to the material for the light-absorbing and disappearing layer is not particularly limited, as long as they are added at the time of film formation. For example, they may be added at the time of synthesis of the polymer constituting the matrix resin, or they may be mixed with the material for the light-absorbing and disappearing layer when preparing a coating solution for the material for the light-absorbing and disappearing layer. Note that, when the radical generator contains a combination of Compound A and Compound B, and Compound A is bonded to the polymer constituting the resin, Compound A is added when the polymer constituting the resin is added. The timing of adding the dye to the material for the wavelength-selective absorption layer is not particularly limited, as long as they are added at the time of film formation. For example, they may be added at the time of synthesis of the polymer constituting the resin, or they may be mixed with the material for the wavelength-selective absorption layer when preparing a coating solution for the material for the wavelength-selective absorption layer.

[0274] -Support Film- The support film used to form the light-absorbing and disappearing layer or the wavelength-selective absorbing layer by a coating method or the like preferably has a film thickness of 2 to 100 μm, more preferably 5 to 100 μm, even more preferably 10 to 75 μm, and particularly preferably 15 to 65 μm. When the film thickness is equal to or greater than the above-mentioned preferable lower limit, sufficient mechanical strength is easily ensured, and defects such as curling, wrinkling, and buckling are unlikely to occur. Furthermore, when the film thickness is equal to or less than the above-mentioned preferable upper limit, when a multilayer film comprising a light-absorbing and disappearing layer or a wavelength-selective absorbing layer and a support film, or even a multilayer film comprising a light-absorbing and disappearing layer, a wavelength-selective absorbing layer, and a support film, is stored, for example, in the form of a long roll, the surface pressure applied to the multilayer film is easily adjusted to an appropriate range, and adhesion defects are unlikely to occur.

[0275] The surface energy of the support film is not particularly limited, but the adhesive strength between the laminate I, laminate II or laminate pre-III and the support film can be adjusted by adjusting the relationship between the surface energy of the material and coating solution of the light-absorbing and dissipating layer or wavelength-selective absorption layer and the surface energy of the surface of the support film on which the light-absorbing and dissipating layer or wavelength-selective absorption layer is to be formed. If the difference in surface energy is reduced, the adhesive strength tends to increase, and if the difference in surface energy is increased, the adhesive strength tends to decrease, and these can be set appropriately.

[0276] The surface roughness of the support film is not particularly limited, but can be adjusted, for example, for the purpose of preventing adhesion failure when a multilayer film of Laminate I, Laminate II, or Laminate pre-III and a support film is stored in the form of a long roll, depending on the relationship between the surface energy, hardness, and surface roughness of the surface of Laminate I, Laminate II, or Laminate pre-III opposite the support film and the surface energy and hardness of the surface of the support film opposite the side on which Laminate I, Laminate II, or Laminate pre-III is formed. Increasing the surface roughness tends to suppress adhesion failure, while decreasing the surface roughness tends to reduce the surface roughness of Laminate I, Laminate II, or Laminate pre-III, and the haze of Laminate I, Laminate II, or Laminate pre-III tends to decrease, and the surface roughness can be appropriately set.

[0277] Any material or film can be used as the support film. Specific examples of the material include polyester polymers (including polyethylene terephthalate), olefin polymers, cycloolefin polymers, (meth)acrylic polymers, cellulose polymers, and polyamide polymers. Furthermore, the support film can be subjected to a surface treatment to adjust its surface properties. For example, corona treatment, room temperature plasma treatment, saponification treatment, etc. can be performed to reduce the surface energy, and silicone treatment, fluorine treatment, olefin treatment, etc. can be performed to increase the surface energy.

[0278] (Diffusion-Preventing Layer) The laminate I is preferably arranged such that the wavelength-selective absorption layer, the diffusion-preventing layer, and the light-absorbing / dissipating layer are in direct contact with each other in this order. The diffusion-preventing layer, when provided between the wavelength-selective absorption layer and the light-absorbing / dissipating layer, has the effect of suppressing the diffusion of components such as dyes contained in the wavelength-selective absorption layer into the light-absorbing / dissipating layer, and has the effect of suppressing the diffusion of components such as dyes and radical generators contained in the light-absorbing / dissipating layer into the wavelength-selective absorption layer. The diffusion of components in the wavelength-selective absorption layer into the light-absorbing / dissipating layer can occur both when the wavelength-selective absorption layer is formed on the light-absorbing / dissipating layer and when the wavelength-selective absorption layer is formed on the light-absorbing / dissipating layer. The diffusion of components in the light-absorbing / dissipating layer into the wavelength-selective absorption layer can occur both when the light-absorbing / dissipating layer is formed on the wavelength-selective absorption layer and when the light-absorbing / dissipating layer is formed on the wavelength-selective absorption layer. By providing a diffusion-preventing layer between the wavelength-selective absorption layer and the light-absorbing and dissipating layer, the laminate I can suppress the diffusion of components in the wavelength-selective absorption layer into the wavelength-selective absorption layer and the diffusion of components in the light-absorbing and dissipating layer into the wavelength-selective absorption layer, as described above. This allows the fading and decolorization reaction of the dye in the light-absorbing and dissipating layer due to ultraviolet irradiation of the laminate I to occur as a fading and decolorization reaction of the dye in the light-absorbing and dissipating layer caused by a compound in the light-absorbing and dissipating layer that generates radicals upon ultraviolet irradiation. The provision of the diffusion-preventing layer makes it possible for the light transmission and absorption filter I obtained using the laminate I to more effectively achieve the desired light absorption characteristics derived from the wavelength-selective absorption layer and the light-absorbing and dissipating layer, respectively.

[0279] In a configuration in which the wavelength-selective absorption layer, the diffusion-preventing layer, and the light-absorbing / dissipating layer are laminated in this order in direct contact with each other, it is believed that when the wavelength-selective absorption layer is formed on the diffusion-preventing layer or when the wavelength-selective absorption layer is formed on the diffusion-preventing layer, the diffusion-preventing layer swells due to the solvent (solvent) in the coating solution for forming the light-absorbing / dissipating layer, and the free volume in the diffusion-preventing layer increases. From this perspective, in the laminate I, it is preferable that the resin constituting the diffusion-preventing layer provided between the wavelength-selective absorption layer and the light-absorbing / dissipating layer has low affinity for the solvent used when forming the wavelength-selective absorption layer or the light-absorbing / dissipating layer on the diffusion-preventing layer. For example, when forming the light-absorbing / dissipating layer on the diffusion-preventing layer, if the components contained in the light-absorbing / dissipating layer, such as dyes and compounds that generate radicals upon ultraviolet irradiation, are materials that dissolve in organic solvents (non-aqueous solvents), it is preferable that the resin constituting the diffusion-preventing layer be a resin with low affinity for organic solvents, i.e., a water-soluble resin. Furthermore, when forming a wavelength-selective absorption layer on a diffusion-preventing layer, if the dye or other component contained in the wavelength-selective absorption layer is a material that dissolves in an organic solvent (non-aqueous solvent), the resin that constitutes the diffusion-preventing layer is preferably a resin that has low affinity for the organic solvent, i.e., a water-soluble resin. The affinity between the solvent used in forming the wavelength-selective absorption layer or the light-absorbing / dissipating layer and the resin that constitutes the diffusion-preventing layer can be evaluated by the solubility parameter δt calculated by the Hoy method. The solubility parameter δt can be calculated, for example, from the literature "Properties of Polymers 3" ｒｄ, ELSEVIER, (1990)”, pages 214-220, column "2) Method of Hoy (1985, 1989)". In the present invention, the absolute value of the difference between the δt value of the solvent used in forming the wavelength-selective absorption layer or the light-absorbing and disappearing layer and the δt value of the resin constituting the diffusion-preventing layer is preferably 1.0 or more, more preferably 2.0 or more, even more preferably 3.0 or more, and particularly preferably 4.0 or more. By adjusting the absolute value of the difference between the δt value of the solvent used when forming the wavelength-selective absorption layer or the light-absorbing and dissipating layer and the δt value of the resin constituting the diffusion-inhibiting layer to be equal to or greater than the above-mentioned preferred value, when the liquid that forms the wavelength-selective absorption layer or the light-absorbing and dissipating layer is applied onto the diffusion-inhibiting layer, the solvent contained in the liquid that forms the wavelength-selective absorption layer or the light-absorbing and dissipating layer is prevented from penetrating the diffusion-inhibiting layer, and swelling of the layer located below the diffusion-inhibiting layer (the light-absorbing and dissipating layer located below the diffusion-inhibiting layer when the wavelength-selective absorption layer is provided on the diffusion-inhibiting layer, or the wavelength-selective absorption layer located below the diffusion-inhibiting layer when the light-absorbing and dissipating layer is provided on the diffusion-inhibiting layer) is effectively suppressed. The upper limit of the absolute value of the difference between the δt value of the solvent used when forming the wavelength-selective absorption layer or the light-absorbing and dissipating layer and the δt value of the resin constituting the diffusion-preventing layer is practically 20.0 or less, and the absolute value of the difference between the δt value of the solvent used when forming the wavelength-selective absorption layer or the light-absorbing and dissipating layer and the δt value of the resin constituting the diffusion-preventing layer is preferably 1.0 to 20.0, more preferably 2.0 to 20.0, even more preferably 3.0 to 20.0, and particularly preferably 4.0 to 20.0. When two or more solvents are used when forming the wavelength-selective absorption layer or the light-absorbing and dissipating layer, the δt value of the solvent means the weight average value of the δt values ​​of each solvent. Furthermore, when the diffusion-preventing layer is composed of two or more resins, the δt value of the resin means the weight average value of each resin.

[0280] (Resin) The resin constituting the diffusion-preventing layer is preferably a water-soluble resin. The water-soluble resin may be either a thermosetting resin or a thermoplastic resin, and in the case of a thermoplastic resin, it may be crystalline or amorphous. For example, polyvinyl alcohol, polyvinylpyridine, (meth)acrylic resin, polyurethane, polyester, epoxy resin, cellulose resin, etc. can be preferably used as the water-soluble resin. At least a portion of these water-soluble resins may be modified. The polyvinyl alcohol may be modified or unmodified. Examples of modified polyvinyl alcohol include modified polyvinyl alcohols into which groups such as acetoacetyl groups and carboxy groups have been introduced. The saponification degree of the polyvinyl alcohol is preferably 60.0 mol% or more, more preferably 80.0 mol% or more, and even more preferably 90.0 mol% or more, from the viewpoint of further improving the barrier properties (permeation suppression performance) of organic solvents. There is no particular upper limit, but 99.99 mol% or less is practical. The saponification degree of the polyvinyl alcohol is a value calculated based on the method described in JIS K 6726 (1994). The (meth)acrylic resin may be any resin containing at least one of a structural unit derived from (meth)acrylic acid and a structural unit derived from a (meth)acrylic acid ester, with a resin containing a structural unit derived from (meth)acrylic acid being preferred. The proportion of structural units derived from (meth)acrylic acid in the total structural units constituting the (meth)acrylic resin is preferably 70 to 100 mol%, more preferably 80 to 100 mol%, and even more preferably 90 to 100 mol%. In particular, the resin constituting the diffusion-preventing layer is preferably at least one of polyvinyl alcohol and a (meth)acrylic resin, and more preferably at least one of polyvinyl alcohol and poly(meth)acrylic acid, from the viewpoint of being able to achieve excellent adhesion between the layers constituting the laminate I.The weight-average molecular weight (Mw) of the resin constituting the diffusion-preventing layer is preferably 10,000 or more, more preferably 10,000 to 200,000, and even more preferably 15,000 to 150,000. The content of the resin (preferably a water-soluble resin) in the diffusion-preventing layer is, for example, preferably 90% by mass or more, more preferably 95% by mass or more. There is no particular upper limit, but it can be 100% by mass.

[0281] The thickness of the diffusion-preventing layer is preferably 0.1 to 5.0 μm, more preferably 0.2 to 4.0 μm, from the viewpoint of further improving the diffusion-preventing ability.

[0282] (Manufacturing method of diffusion-preventing layer) The method of forming the diffusion-preventing layer is not particularly limited, for example, by a conventional casting method such as spin coating and slit coating, the method of forming on the wavelength selective absorption layer or the light-absorbing and disappearing layer can be mentioned.The solvent used in this case can be used without any particular limitation as long as it can obtain the desired diffusion-preventing layer.For example, when the resin constituting the diffusion-preventing layer is a water-soluble resin, it is preferable to use water-soluble solvents such as water; alcohols such as ethanol and isopropyl alcohol.

[0283] The diffusion-preventing layer is not limited to being disposed between the wavelength-selective absorption layer and the light-absorbing and dissipating layer in the laminate I, but may be disposed between any two adjacent layers constituting each of the laminates I, II, and pre-III. For example, in the laminate pre-III, a preferred configuration is one in which the support film, the diffusion-preventing layer, and the light-absorbing and dissipating layer are arranged in this order so as to be in direct contact with each other. In this case, the diffusion-preventing layer can be formed on the support film by the above-mentioned method.

[0284] <Film Thickness of the Light-Absorbing and Disappearing Layer and the Wavelength-Selective Absorbing Layer> The film thicknesses of the light-absorbing and disappearing layer and the wavelength-selective absorbing layer are not particularly limited, but are preferably 1 to 18 μm, more preferably 1 to 12 μm, and even more preferably 1 to 8 μm. When the film thickness is below the preferred upper limit, adding a high concentration of dye to a thin film can suppress a decrease in polarization degree due to fluorescence emitted by the dye (pigment). Furthermore, the effect of the quencher is easily exhibited in the light-absorbing and disappearing layer. On the other hand, when the film thickness is above the preferred lower limit, it becomes easier to maintain uniformity of in-plane absorbance. In the present invention, a film thickness of 1 to 18 μm means that the thickness of the light-absorbing and disappearing layer or the wavelength-selective absorbing layer is within the range of 1 to 18 μm, regardless of the location where it is measured. This also applies to film thicknesses of 1 to 12 μm and 1 to 8 μm. The film thickness can be measured using an electronic micrometer (e.g., manufactured by Anritsu Corporation).

[0285] <Absorbance of Laminate I, Laminate II, and Laminate Pre-III> In the laminate I, laminate II, and laminate pre-III, the absorbance at the wavelength showing maximum absorption in the wavelength range of 400 to 700 nm (hereinafter simply referred to as "Ab(λ ｍａｘ The largest absorbance among the laminates I, II, and pre-III is preferably 0.3 or more, more preferably 0.5 or more, and even more preferably 0.7 or more. However, the absorbance of the laminates I, II, and pre-III can be adjusted by the type and amount of dye added or the film thickness.

[0286] <Decolorization rate of light-absorbing and dissipating layer> The light-absorbing and dissipating layer in the laminate I and laminate pre-III preferably has a decolorization rate of 85% or more, more preferably 87% or more, and even more preferably 90% or more, when irradiated with ultraviolet light at 25°C. There is no particular upper limit, and the decolorization rate is preferably 100%. The decolorization rate is determined by the Ab(λ) before and after the ultraviolet light irradiation test. ｍａｘ ) is calculated by the following formula: Decolorization rate (%) = 100 - (Ab(λ) after ultraviolet irradiation) ｍａｘ ) / Ab(λ) before UV irradiation ｍａｘ)) × 100 Here, the ultraviolet irradiation test is carried out under atmospheric pressure (101.33 kPa) using an ultra-high pressure mercury lamp (for example, manufactured by HOYA Corporation, product name: UL750) at an illuminance of 100 mW / cm ２ , irradiation amount 2000mJ / cm ２ The laminate I and the laminate pre-III are irradiated with ultraviolet light at room temperature (45° C.). The absorbance and ultraviolet irradiation test can be measured and calculated by the method described in [Measurement of absorbance of first and second portions].

[0287] Furthermore, it is preferable that the light-absorbing and dissipative layer hardly generates absorption (secondary absorption) derived from a new colored structure accompanying decomposition of the dye. For example, the presence or absence of absorption derived from a new colored structure accompanying decomposition of the dye can be determined by the above Ab(λ ｍａｘ The specific wavelength is selected at which the dye before UV irradiation shows almost no absorption and at which new absorption due to decomposition of the dye is observed. As a specific example, the presence or absence of absorption due to the new colored structure accompanying decomposition of the dye can be confirmed based on the ratio of the absorbance at a specific wavelength to the above Ab(λ ｍａｘ The specific wavelength is selected at which the dye before UV irradiation shows almost no absorption and at which new absorption due to decomposition of the dye is observed. As a specific example, the presence or absence of absorption due to the new colored structure accompanying decomposition of the dye can be confirmed based on the ratio of the absorbance at a specific wavelength to the above Ab(λ ｍａｘ The absorbance at a wavelength of 450 nm (hereinafter also referred to simply as "Ab(450)") to the ... ｍａｘ )) × 100% (II) (Ab(450) after UV irradiation / Ab(λ) before UV irradiation ｍａｘ)) × 100% Alternatively, the absorbance at a wavelength of 650 nm (hereinafter also referred to simply as "Ab(650)") may be used instead of the absorbance at a wavelength of 450 nm, and the evaluation can also be performed by subtracting the ratio of the following (III) from the ratio of the following (IV). A preferred range of the value obtained by subtracting the ratio of the following (III) from the ratio of the following (IV) is the same as the value obtained by subtracting the ratio of (I) from the ratio of the above formula (II). (III) (Ab(650) before ultraviolet irradiation / Ab(λ ｍａｘ )) × 100% (IV) (Ab(650) after ultraviolet irradiation / Ab(λ) before ultraviolet irradiation ｍａｘ )) × 100% Here, the description of the ultraviolet irradiation test for the extinction rate above can be preferably applied to the ultraviolet irradiation test.

[0288] The light-absorbing and dissipating layer can exhibit excellent discoloration properties when the discoloration rate and the value for confirming the presence or absence of absorption due to a new colored structure accompanying decomposition of the dye both fall within preferred ranges.

[0289] In the light transmission-absorption filter I obtained using the laminate I and the light transmission-absorption filter II obtained using the laminate pre-III, the ultraviolet ray-unirradiated portion (portion having a light absorbing effect) in the light-absorbing and disappearing layer has Ab(λ) according to the laminate I, laminate II, and laminate pre-III. ｍａｘ ) is preferably satisfied.

[0290] <Treatment of Laminate I, Laminate II, and Laminate Pre-III> The Laminate I, Laminate II, and Laminate Pre-III may be subjected to a hydrophilization treatment such as a glow discharge treatment, a corona discharge treatment, or an alkaline saponification treatment, and corona discharge treatment is preferably used. It is also preferable to apply the methods disclosed in JP-A-6-94915 or JP-A-6-118232.

[0291] The obtained film may be subjected to a heat treatment step, a superheated steam contact step, an organic solvent contact step, etc., as required. In addition, a surface treatment may be appropriately performed.

[0292] Furthermore, the pressure-sensitive adhesive layer may be a layer made of a pressure-sensitive adhesive composition having a base polymer such as a (meth)acrylic resin, a styrene resin, a silicone resin, or the like, to which a crosslinking agent such as an isocyanate compound, an epoxy compound, or an aziridine compound has been added. Preferably, the description of the pressure-sensitive adhesive layer in the OLED display device described below can be applied.

[0293] <Gas Barrier Layer> The laminate I may have a gas barrier layer on at least one surface. When the laminate I has a gas barrier layer, the laminate I can be a laminate I that achieves both excellent decolorization properties and excellent light fastness, and can be suitably used to produce the above-mentioned light transmission-absorption filter I. The laminate II may have a gas barrier layer. In particular, when the laminate II has two layers, the first wavelength selective absorption layer and the second wavelength selective absorption layer, it is preferable to have a gas barrier layer between these layers. This not only suppresses decomposition of the dye by oxygen gas, but also suppresses energy transfer between the first and second wavelength selective absorption layers, thereby further suppressing decomposition of the dye. Furthermore, the laminate pre-III may have a gas barrier layer on at least one surface. When the laminate pre-III has a gas barrier layer, the laminate pre-III can be a laminate pre-III that achieves both excellent decolorization properties and excellent light fastness, and can be suitably used to produce the above-mentioned light transmission-absorption filter II.

[0294] The material for forming the gas barrier layer is not particularly limited, and examples thereof include organic materials (preferably crystalline resins) such as polyvinyl alcohol and polyvinylidene chloride, organic-inorganic hybrid materials such as sol-gel materials, and SiO ２ , SiO ｘ , SiON, SiN ｘ and Al ２ O ３ The gas barrier layer may be a single layer or a multilayer, and in the case of a multilayer, examples of the gas barrier layer include an inorganic dielectric multilayer film and a multilayer film in which organic materials and inorganic materials are alternately laminated.

[0295] The laminate I has a gas barrier layer at least on the surface that will come into contact with air when the above-mentioned light transmission-absorption filter I is used, thereby suppressing a decrease in the absorption intensity of the dye in the light transmission-absorption filter I. As long as a gas barrier layer is provided at the interface of the laminate I that comes into contact with air, the gas barrier layer may be provided on only one surface of the laminate I, or on both surfaces. The laminate pre-III has a gas barrier layer at least on the surface of the light-absorbing and disappearing layer that will come into contact with air, thereby suppressing a decrease in the absorption intensity of the dye in the light-absorbing and disappearing layer in the state of the laminate pre-III and the laminate III obtained by exposing the laminate pre-III with a mask. As long as a gas barrier layer is provided at the interface of the laminate pre-III that comes into contact with air, the gas barrier layer may be provided on only one surface of the laminate pre-III, or on both surfaces. From the same viewpoint as the light transmission-absorption filter I obtained using the laminate I, it is preferable to provide a gas barrier layer in the light transmission-absorption filter of the present invention, and the description of the laminate I can be applied.

[0296] In particular, when the gas barrier layer contains a crystalline resin, the gas barrier layer contains a crystalline resin, has a layer thickness of 0.1 μm to 10 μm, and has an oxygen permeability of 60 cc / m ２ In the gas barrier layer, the "crystalline resin" is a resin that has a melting point at which it undergoes a phase transition from crystal to liquid when the temperature is increased, and is capable of imparting gas barrier properties related to oxygen gas to the gas barrier layer. ２ The "gas barrier layer having a gas barrier density of 1000 psi or less per 1000 psi day atm" is the same as the gas barrier layer described in paragraphs

[0180] to

[0184] of WO 2022 / 149510, and the descriptions therein can be applied as they are.

[0297] <Method for manufacturing gas barrier layer> The method for forming the gas barrier layer is not particularly limited, but includes a conventional method, for example, in the case of an organic material, a casting method such as spin coating or slit coating, etc. Also includes a method of laminating a commercially available resin gas barrier film or a pre-prepared resin gas barrier film, etc. Furthermore, in the case of an inorganic material, examples of the method include a plasma enhanced chemical vapor deposition (CVD) method, a sputtering method, and a vapor deposition method.

[0298] When the laminate I has the gas barrier layer, for example, a method can be used in which the gas barrier layer is formed directly on the laminate I, which does not have a gas barrier layer and is produced by the above-mentioned production method. In this case, it is also preferable to subject the surface of the laminate I, on which the gas barrier layer is to be formed, to corona treatment. When the laminate II has the gas barrier layer, for example, a method can be used in which the gas barrier layer is formed directly on the first wavelength selective absorption layer or the second wavelength selective absorption layer produced by the above-mentioned production method. In this case, it is preferable that at least one (preferably both) of the first wavelength selective absorption layer and the second wavelength selective absorption layer, on which the gas barrier layer is to be formed, contains the polymer having the oxazoline ring group described above, from the viewpoint of interlayer adhesion. When the laminate pre-III has the gas barrier layer, for example, a method can be used in which the gas barrier layer is formed directly on the light-absorbing and dissipating layer produced by the above-mentioned production method. In this case, it is also preferable to subject the light-absorbing and dissipating layer to corona treatment on the surface on which the gas barrier layer is to be formed. Furthermore, when any of the optically functional films described below is included, it is also preferable to attach them via an adhesive layer. For example, it is also preferable to provide a gas barrier layer on the laminate of Laminate I, Laminate II, or Laminate pre-III, and then to attach an optically functional film thereto via a pressure-sensitive adhesive layer.

[0299] <Optical Functional Film> The laminate I, laminate II, and laminate pre-III may appropriately include the gas barrier layer or any optical functional film as long as the effects of the present invention are not impaired. The optical properties and materials of the optional optical functional film are not particularly limited, but a film containing (or having as its main component) at least one of cellulose ester resin, acrylic resin, cyclic olefin resin, and polyethylene terephthalate resin can be preferably used. An optically isotropic film or an optically anisotropic retardation film may be used. As the optional optical functional film containing a cellulose ester resin, for example, Fujitac TD80UL (trade name, manufactured by Fujifilm Corporation) can be used. Examples of the optically functional film containing an acrylic resin include an optical film containing a (meth)acrylic resin containing a styrene-based resin as described in Japanese Patent No. 4,570,042, an optical film containing a (meth)acrylic resin having a glutarimide ring structure in the main chain as described in Japanese Patent No. 5,041,532, an optical film containing a (meth)acrylic resin having a lactone ring structure as described in Japanese Patent Laid-Open No. 2009-122664, and an optically functional film containing a (meth)acrylic resin having a glutaric anhydride unit as described in Japanese Patent Laid-Open No. 2009-139754. Examples of the optically functional film containing a cyclic olefin resin include a cyclic olefin resin film as described in paragraph

[0029] and subsequent paragraphs of Japanese Patent Laid-Open No. 2009-237376, and a cyclic olefin resin film containing an additive that reduces Rth as described in Japanese Patent No. 4,881,827 and Japanese Patent Laid-Open No. 2008-063536.

[0300] <Method for Manufacturing Light-Transmission-Absorption Filter I> The light-transmission-absorption filter I can be obtained by irradiating the laminate I with ultraviolet light and performing masked exposure. The mask pattern is preferably such that the regions corresponding to the non-light-emitting portions of the OLED display element (regions from which display light is not emitted) become the second regions described above, and the regions corresponding to the light-emitting portions of the OLED display element (regions from which display light is emitted) become the first regions described above. That is, the light-transmission-absorption filter I can be suitably obtained by irradiating the laminate I with ultraviolet light using a mask pattern that masks the regions corresponding to the non-light-emitting portions of the OLED display element and does not mask the regions corresponding to the light-emitting portions of the OLED display element. The area ratio between the non-light-emitting portions of the OLED display element and the light-emitting portions of the OLED display element is as described above. The conditions for ultraviolet irradiation can be appropriately adjusted so as to obtain a light-transmission-absorption filter I having a first region including a light-absorption-loss region. For example, the pressure conditions can be atmospheric pressure (101.33 kPa), the temperature conditions can be mild conditions of 10 to 60°C, the lamp output can be 10 to 320 W / cm, and the lamp to be used can be an air-cooled metal halide lamp, a mercury lamp such as an ultra-high pressure mercury lamp, or the like. The irradiation dose can be 200 to 5000 mJ / cm. ２ It can be said that:

[0301] <Method for Manufacturing Light-Transmission-Absorption Filter II> The light-transmission-absorption filter II can be obtained by laminating the laminate II with a laminate III obtained by irradiating the laminate pre-III with ultraviolet light and masked exposure. Regarding the mask pattern, the area ratio between the non-emitting portions of the OLED display element and the emitting portions of the OLED display element, and the conditions for ultraviolet irradiation, the descriptions relating to the mask pattern, the area ratio between the non-emitting portions of the OLED display element and the emitting portions of the OLED display element, and the conditions for ultraviolet irradiation in the light-transmission-absorption filter I can be applied by replacing laminate I with laminate pre-III and light-transmission-absorption filter I with laminate III. The method for laminating the laminate II and the laminate III is not particularly limited; they may be laminated via an adhesive layer, or a laminate structure may be produced by bonding them together. The adhesive layer may be the same as the description of the adhesive layer described below.

[0302] The light transmission / absorption filter of the present invention may have the above-mentioned optical functional film. The light transmission / absorption filter of the present invention may also have a layer containing an ultraviolet absorber. The ultraviolet absorber is not particularly limited and a commonly used compound can be used, for example, the ultraviolet absorber in the ultraviolet absorbing layer described below. The resin constituting the layer containing an ultraviolet absorber is also not particularly limited and for example, the resin in the ultraviolet absorbing layer described below can be used. The content of the ultraviolet absorber in the layer containing the ultraviolet absorber is appropriately adjusted depending on the purpose.

[0303] [Display Element Intermediate] In the production of the OLED display element of the present invention including the light-transmitting / absorbing filter I, it is also preferable to use a display element intermediate including the laminate I. As long as the display element intermediate includes the laminate I, the other components of the display element intermediate can be the same as those of an OLED display element commonly used in display devices, without any particular limitations. In the display element intermediate, the laminate I and the OLED display element may be laminated so as to be in direct contact with each other, or may be bonded together via an adhesive layer. The adhesive layer may be the same as the adhesive layer described below. Furthermore, in addition to the adhesive layer, an optional layer such as a barrier film may be laminated via an additional layer. Any layer commonly used in OLED display elements, such as the barrier film, may be used as appropriate, and the barrier film may be the same as the gas barrier layer described above. In the display element intermediate, the laminate structure may be such that either the wavelength-selective absorption layer or the light-absorbing / disappearing layer in the laminate I is close to the OLED display element. In the above-mentioned display element intermediate product, it is preferable that the wavelength-selective absorption layer in laminate I be closer to the OLED display element than the light-absorbing and disappearing layer, from the viewpoint of being able to discolor the light-absorbing and disappearing layer with a small amount of ultraviolet light irradiation.

[0304] [OLED Display Element] The OLED display element of the present invention includes the light-absorbing filter of the present invention, and preferably includes the above-described light-absorbing filter I or II. As long as the OLED display element of the present invention includes the light-absorbing filter of the present invention, the other components of the OLED display element commonly used in display devices can be used without particular limitations. (OLED Display Element Including Light-Transmitting-Absorbing Filter I) The OLED display element of the present invention is obtained by exposing the display element intermediate to ultraviolet light using a mask, thereby converting the laminate I included in the display element intermediate into the light-transmitting-absorbing filter I. In other words, the display element intermediate is an intermediate product as a precursor to the OLED display element of the present invention, and the OLED display element of the present invention is a finished product. As described above, the OLED display element of the present invention has a configuration in which the first portion of the light-transmitting-absorbing filter of the present invention is disposed on the light-emitting portion of the OLED display element, and the second portion of the light-transmitting-absorbing filter of the present invention is disposed on the non-light-emitting portion of the OLED display element.

[0305] (OLED Display Element Including Light-Transmitting-Absorbing Filter II) Furthermore, an OLED display element of the present invention including the light-transmitting-absorbing filter II can be obtained, for example, by first preparing the light-transmitting-absorbing filter II having first and second regions corresponding to the pattern of the light-emitting and non-emitting portions of the OLED display element, and then bonding the light-transmitting-absorbing filter II to the OLED display element or laminating the filter II via another layer. The same description of the lamination of the laminate I and the OLED display element as above can be applied to the lamination of the light-transmitting-absorbing filter II and the OLED display element. In an OLED display element of the present invention including the light-transmitting-absorbing filter II, the laminate structure may be such that either the laminate II or the laminate III in the light-transmitting-absorbing filter II is closer to the OLED display element. Note that, as described below, from the viewpoint of easily realizing suppression of color shift due to the viewing angle of the display light, it is preferable that the laminate III be closer to the OLED display element than the laminate II.

[0306] In an OLED display element including a light-transmitting-absorbing filter II, adjusting the distance between the laminate III in the light-transmitting-absorbing filter II and the OLED display element layer can suppress the effect on the transmittance of display light (reduction in brightness) while adjusting the viewing angle dependence of the color of the display light when applied to an OLED display device having a microcavity structure. This is because, as the distance between the laminate III in the light-transmitting-absorbing filter II and the OLED display element layer increases, the proportion of light transmitted through the second portion in the total display light perceived by the viewer increases due to the effect of parallax. The distance between the laminate III and the OLED display element layer can be, for example, 2 to 45 μm. From the viewpoint of simultaneously suppressing a change in color of the display light due to the viewing angle by keeping the ratio of the light transmitted through the second portion to the total display light perceived by the viewer at a certain level or more, and suppressing a decrease in brightness by keeping the ratio of the light absorbed by the second portion to the total display light perceived at a certain level or less, the distance between the laminate III and the OLED display element layer is preferably 5 to 35 μm, more preferably 10 to 30 μm, still more preferably 15 to 28 μm, and most preferably 20 to 25 μm. Note that the "distance between the laminate III and the OLED display element layer" is synonymous with the "distance d between the laminate III and the light-emitting element layer" in OLED display elements II-1 to II-3 described below.

(x can be a blue pixel (B), a green pixel (G), a red pixel (R), etc.) R ｘ (λ) = R ｘ０ (λ) × T １ (λ) ２ +R Ｓ (2) Reflectance of non-light-emitting portion Reflection spectrum R of non-light-emitting portion ｙ (λ) is the reflectance spectrum R of the non-emitting part of the OLED substrate measured by microspectroscopyｙ０ (λ) and the transmission spectrum T of the second portion ２ (λ) and the surface reflectance R Ｓ The surface reflectance R Ｓ R is the surface reflectance of the laminate of transparent members on the surface side (viewer side) of the second portion, and specifically means the surface reflectance of the gas barrier layer. ｙ (λ) = R ｙ０ (λ) × T ２ (λ) ２ +R Ｓ (3) Average Reflectance The reflectance spectrum of the entire display device is calculated by subtracting the reflectance spectrum R of the light-emitting portion calculated above. ｘ (λ) and the reflection spectrum R of the non-emitting part ｙ The reflectance spectrum obtained is multiplied by the CIE standard illuminant D65 spectrum and the photopic standard relative luminosity factor, and the sum is calculated (visibility correction is performed). This gives the luminosity-corrected reflectance Y (hereinafter also simply referred to as "reflectance") and the color of the reflected light (a ＊ , b ＊ ) was calculated. In this simulation, a commercially available smartphone, iPhone (registered trademark) 14 Pro (trade name, manufactured by APPLE Inc.), was used as the OLED substrate, and the OLED light-emitting layer was peeled off from the touch sensor layer, and the layer above the touch sensor layer (on the viewer's side) was removed. The area ratio of the light-emitting portion (light-emitting portion of each color, BGR) and the non-light-emitting portion of the iPhone (registered trademark) 14 Pro was calculated as B (blue): G (green): R (red): non-light-emitting portion = 15:10:5:70.

[0354] The results are summarized in Table 2. Nos. 101 to 104 are simulation results for the light transmission-absorption filter of the present invention, performed using the transmittance simulation results for the first region and the second region obtained using laminate Nos. 101 to 104 prepared above. Nos. c201 and c202 are simulation results for a light transmission-absorption filter for comparison, performed using the transmittance simulation results for the first region and the second region obtained using laminate Nos. c201 and c202 prepared above.

[0357] As shown in Table 2, the light transmission and absorption filters No. c201 and c202 have the following characteristics: ＊ a ＊ b ＊ a in color space ＊ and b ＊ However, none of these filters satisfy the requirements of the present invention in that the sign of the value in the first region and the sign of the value in the second region are reversed. Of these filters, the light transmission / absorption filter No. c201 has a high reflectance of 8.9%, which means that it is not possible to suppress the reflection of external light. The light transmission / absorption filter No. c202 has a high reflectance of 8.9%, which means that it is not possible to suppress the reflection of external light. ＊ In contrast, the light transmission-absorption filters Nos. 101 to 104 are light transmission-absorption filters that ensure the desired transmittance of display light when incorporated into a display device, and have a low reflectance of 6.7% or less, which can suppress external light reflection at a high level, and further, the a of reflected light ＊ and b ＊ is within the range of −2.8 to 6.3, and a of the display light (first portion and second portion) ＊ and b ＊ was found to be within the range of −9.3 to 28.0, and the color of both the reflected light and the displayed light could be adjusted to a neutral color.
