Description

Color filter, solid-state image sensor, method for manufacturing a color filter

[0001] The present invention relates to a color filter, a solid-state image sensor, and a method for manufacturing a color filter.

[0002] Solid-state image sensors such as CCD (Charge Coupled Device) image sensors and CMOS (Complementary Metal-Oxide Semiconductor) image sensors, as well as liquid crystal display devices, utilize color filters that handle various color performance characteristics. Typically, color filters have colored pixels containing colorants.

[0003] As a dye that can be used as a coloring agent for the colored pixels described above, for example, Patent Document 1 discloses a compound with a predetermined structure.

The partitions can be formed by known methods, for example, by forming a film of a partition-forming composition on a support and forming a pattern with openings by lithography.

[0217] As described above, this color filter may have colored pixels that do not contain the specific compound. The details of the colored pixels that do not contain the specific compound are the same as those of the colored pixels, except that they contain only dyes different from the specific compound described above.

[0219] Figure 1 shows a schematic cross-sectional view of one embodiment of the color filter. The color filter 100 shown in Figure 1 is provided on a support 200 and has a configuration in which red pixels 110, blue pixels 112, and green pixels 114 are provided in the openings of a black matrix 120. In the color filter 100 shown in Figure 1, at least one of the red pixels 110, blue pixels 112, and green pixels 114 is the colored pixel, and it is preferable that all of them are colored pixels. The color filter 100 shown in Figure 1 has a configuration in which each pixel is partitioned by a black matrix 120, but the color filter does not have to have a black matrix. The color filter 100 shown in Figure 1 has colored pixels of three different hues, but is not limited to this, and the number of hues may be two or less, or four or more. The arrangement and number of each colored pixel and black matrix may be changed as appropriate depending on the application and characteristics. In the color filter 100 shown in Figure 1, the thickness of each colored pixel and the black matrix 120 are the same, but the thickness of each component may be different. Also, in the color filter 100 shown in Figure 1, each colored pixel is made up of a single layer, but each colored pixel may be made up of multiple layers. As the support 200 shown in Figure 1, for example, the support used in the color filter manufacturing method described later can be used.

[0220] [Applications] The applications of this color filter are not particularly limited, but examples include solid-state image sensors and image display devices, which will be described later. This color filter can be suitably used as a color filter in optical filters and modules used in portable devices such as personal computers, tablets, mobile phones, smartphones, and digital cameras; OA (Office Automation) equipment such as printers and scanners; industrial equipment such as surveillance cameras, barcode readers, automated teller machines (ATMs), high-speed cameras, and devices with personal authentication functions using facial recognition or biometric authentication; in-vehicle camera equipment; medical camera equipment such as endoscopes, capsule endoscopes, and catheters; and space equipment such as biosensors, biosensors, military reconnaissance cameras, 3D map cameras, weather and ocean observation cameras, land resource exploration cameras, and space exploration cameras for astronomy and deep space targets.

[0221] [Method for Manufacturing a Color Filter] The method for manufacturing this color filter is not particularly limited as long as it is a method that can manufacture this color filter, but a method including the following steps 1 and 2 is preferred. Step 1: A step of forming a film containing a specific compound on a support. Step 2: A step of removing a part of the film to form colored pixels.

[0222] [Step 1] Step 1 is a film formation step in which a film containing a specific compound (hereinafter also referred to as the "specific film") is formed on a support. The support in Step 1 is not particularly limited and includes silicon substrates, glass substrates, epoxy substrates, and resin substrates, with silicon substrates being preferred. Photodetectors such as charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor devices (CMOS), as well as transparent conductive films, may be formed on the substrate. The substrate may have an undercoat layer to improve adhesion with the specific film, prevent diffusion, and planarize. For example, the support may be a laminate in which a silicon substrate, a photodetector, and an undercoat layer are stacked in this order. The undercoat layer may include a layer for removing a part of the film in Step 2, and may be in the shape of a pattern. The undercoat layer may be an organic layer, an inorganic layer, or an organic-inorganic composite layer, with an organic layer (for example, a resin-containing layer) being preferred. The support may have only one undercoat layer, or two or more layers. The support may also have colored pixels.

[0223] In step 1, methods for forming a specific film on a support include, for example, a dry film formation method and a method of forming a coating film by applying a colored pixel-forming composition (hereinafter also referred to as the "coating method"), with the dry film formation method being preferred.

[0224] <Dry Film Formation Method> Examples of the dry film formation methods include vapor deposition (especially vacuum deposition), sputtering, ion plating, and physical vapor deposition methods such as MBE (Molecular Beam Epitaxy), as well as CVD (Chemical Vapor Deposition) methods such as plasma polymerization. Vapor deposition is preferred, and vacuum deposition is more preferred. Manufacturing conditions such as the degree of vacuum and deposition temperature in the vapor deposition method can be set according to conventional methods. In particular, specific films are preferably formed by vapor deposition of specific compounds because they are easy to form thin films and easy to form films with a high content of specific compounds.

[0225] If the specific film contains components other than the specific compound, the other components may be deposited simultaneously or sequentially with the specific compound in step 1. For example, the film may be deposited by vapor deposition using a raw material mixture of the specific compound and the other components, or the film may be deposited using the specific compound and the other components as vapor deposition sources, respectively. This allows for the formation of a specific film in which the specific compound is dispersed within the other components. Examples of other components include dyes other than the specific compound, silane coupling agents, inorganic compounds, and organic polymers or their precursors. Details of dyes other than the specific compound, silane coupling agents, inorganic compounds, and organic polymers are as described above as other components that may be included in the colored pixels. Note that the above-mentioned precursors of organic polymers refer to compounds that polymerize to form organic polymers by dry deposition, such as vapor deposition polymerization.

[0226] In the dry film formation method, the content of the specific compound relative to the total mass of the raw materials used is preferably 10% by mass or more, more preferably 20% by mass or more, and even more preferably 30% by mass or more. There is no particular upper limit, and it may be 100% by mass or less, or 90% by mass or less. In addition, in the dry film formation method, the content of the dye relative to the total mass of the raw materials used is preferably 50% by mass or more, more preferably 60% by mass or more, and even more preferably 70% by mass or more. There is no particular upper limit, and it may be 100% by mass or less, or 90% by mass or less.

[0227] If the specific film contains components other than the dye, it is also preferable to dry-form the film using a composition containing the specific compound and the other components. In the above composition, the content of the other components is preferably 1 to 50% by mass, and more preferably 5 to 25% by mass, relative to the total dye contained in the composition.

[0228] The film thickness of the specific film formed by the dry deposition method is greater than 0 nm, preferably 100 nm or more, and more preferably 150 nm or more. Furthermore, from the viewpoint of improving the sensitivity of the solid-state image sensor, the film thickness of the colored pixels is preferably 1000 nm or less, more preferably 700 nm or less, even more preferably less than 500 nm, and particularly preferably less than 400 nm. In particular, with the dry deposition method, since thin films can be easily formed, it is also preferable that the film thickness be less than 300 nm, more preferably less than 250 nm, and even more preferably less than 225 nm.

[0229] <Coating Method> The coating method is a method of forming a coating film by applying a colored pixel-forming composition onto a support.

[0242] Colored pixel-forming compositions can be manufactured by known methods. For example, it is preferable to manufacture a dispersion of dyes and then mix the resulting dispersion with other components.

[0243] If the specific film is multilayered, the above film formation process may be repeated multiple times. Furthermore, if the specific film is a multilayered film consisting of a film containing only dyes other than the specific compound and a film containing the specific compound, step 1 may include a step of forming a film containing the specific compound and a step of forming a film containing only dyes other than the specific compound.

[0244] [Step 2] Step 2 is a step of removing a portion of the specific film formed in Step 1 to form a colored pixel. The method of removing a portion of the specific film is not particularly limited; for example, it may be directly removed by processing a portion of the specific film by etching and developing, or the specific film may be removed by removing a portion of a layer adjacent to the specific film (for example, the layer below the specific film). Specific methods for removing a portion of the specific film are described in detail in embodiments P1 to P6 described later.

[0245] The method for manufacturing a color filter may include steps other than steps 1 and 2. Other steps include, for example, the other steps in the manufacturing methods of embodiments P1 to P6 described later, the step of forming a partition wall, and the step of forming a protective layer. Known methods can be used for the steps of forming the partition wall and forming the protective layer.

[0246] [Aspects P1 to P6] More specific aspects of the method for forming the colored pixels in the manufacturing method of the color filter are the manufacturing methods in the following aspects P1 to P6. Aspect P1: Having step 1, step X1 after step 1 in which a photosensitive resin layer is provided on a specific film, step X2 in which a pattern exposure treatment and development treatment are applied to the photosensitive resin layer to form a pattern, and step 2 in which the specific film is etched using the pattern as a mask to form colored pixels. Aspect P2: Having step X3 before step 1 in which a photosensitive resin layer is provided on a support, step 1, and step 2 in which the pattern exposure treatment and development treatment are applied to the photosensitive resin layer to form colored pixels arranged on the pattern. Aspect P3: Having step 1 and step 2 in which the specific film is photosensitive, and in step 2 in which a pattern exposure treatment and development treatment are applied to the film to form colored pixels. Aspect P4: Having step 1 and step 2 in which a part of the specific film is removed using an electron beam to form colored pixels. Embodiment P5: The embodiment includes a step X3 in which a photosensitive resin layer is provided on a support before step 1, a step X4 in which a pattern exposure treatment and a development treatment are performed on the photosensitive resin layer to form a pattern, step 1, and step 2, in which the pattern and a specific film on the pattern are removed to form colored pixels. Embodiment P6: The embodiment includes a step X5 in which a specific film is formed on a substrate, and a step X6 in which a part of the specific film is transferred onto a support using an electron beam to form colored pixels. Each embodiment will be described in detail below.

[0247] <Aspect P1> The method for manufacturing a color filter according to aspect P1 comprises, in this order, step 1, step X1 of providing a photosensitive resin layer on a specific film obtained in step 1, step X2 of applying a pattern exposure treatment and a development treatment to the obtained photosensitive resin layer to form a pattern, and step 2.

[0248] The details of step 1 in embodiment P1 are as described above.

[0249] Step X1 is a step of providing a photosensitive resin layer on a specific film. The photosensitive resin layer in step X1 is not particularly limited, and known positive-type photosensitive resin layers and negative-type photosensitive resin layers can be used. The method of forming the photosensitive resin layer is not particularly limited, and examples include a method of applying a photosensitive resin layer forming composition and drying it, and a method of using a transfer film having a photosensitive resin layer. In forming the photosensitive resin layer, it is also preferable to perform a pre-bake treatment before step X2, which will be described later. Furthermore, in order to prevent the dissolution of components in the specific film, a protective film may be formed on the specific film before forming the photosensitive composition layer. The above protective film is not particularly limited, and may be an organic layer, an inorganic layer, or an organic-inorganic composite layer.

[0250] Step X2 is a step in which a pattern is formed on the photosensitive resin layer formed in step X1 by applying a pattern exposure treatment and a development treatment. The pattern exposure is preferably performed by exposure through a predetermined mask pattern. The exposure light can be appropriately selected according to the composition and pattern of the photosensitive resin layer. The development treatment can be a method of removing a part of the pattern-exposed photosensitive resin layer with a developer. The developer can be any one that can remove the exposed part of the positive-type photosensitive resin composition or the unexposed part of the negative-type photosensitive resin composition, and it is preferable that it does not dissolve a specific film. As the developer, for example, known alkaline developers and organic solvent-based developers can be used. It is also preferable to perform post-exposure heat treatment and post-development heat treatment (post-bake treatment) in step X2.

[0251] Step 2 in embodiment P1 is a method of removing a portion of a specific film using the pattern formed in step X2 as an etching mask. Examples of methods for removing a portion of the specific film include dry etching and wet etching, with dry etching being preferred. Details of the dry etching method can be found in paragraphs

[0010] to

[0067] of Japanese Patent Application Publication No. 2013-064993, and this content is incorporated herein by reference.

[0252] The process may further include a step of removing a pattern derived from the photosensitive resin layer on a specific film after step 2. The method for removing the pattern is not particularly limited, and for example, a method using a stripping solution can be cited. For details of the method for removing the pattern, refer to paragraphs

[0047] to

[0055] of Japanese Patent Application Publication No. 2013-064993, and these contents are incorporated herein by reference.

[0253] <Aspect P2> The method for manufacturing a color filter according to aspect P2 comprises, in this order, step X3, which involves providing a photosensitive resin layer on a support before step 1, step 1, and step 2.

[0254] Step X3 is a step of providing a photosensitive resin layer on a support. The support can be the support mentioned above as the support in Step 1. The method for Step X3 can be the method of Step X1 in Embodiment P1 described above.

[0255] Step 1 in embodiment P2 is the step of forming a specific film on the photosensitive resin layer formed in step X3. The details of the method for forming the specific film are as described above.

[0256] In embodiment P2, the specific film preferably contains a dye soluble in the developer used in step 2 and a dye insoluble in the developer. This is preferable because a portion of the specific film can be efficiently removed in step 2, and the dye in the colored pixels is less likely to be excessively removed. It is also preferable that the specific film contains a transparent material (components other than the dye) soluble in the developer and a dye insoluble in the developer. In particular, it is preferable that the specific film contains a specific compound unnecessary for the developer and a component soluble in the developer.

[0257] Step 2 in embodiment P2 is a step of applying a pattern exposure treatment and a development treatment to the photosensitive resin layer formed in step X3. As a result, a portion of the photosensitive resin layer and a specific film that was placed on the photosensitive resin layer to be removed are removed, and a pattern derived from the photosensitive resin layer and colored pixels placed on the pattern are formed. The method of step X2 described above can be used as the pattern exposure treatment and development treatment method for the photosensitive resin layer.

[0258] <Aspect P3> The method for manufacturing a color filter according to aspect P3 comprises step 1 and step 2 in that order, and the specific film is photosensitive.

[0259] The details of step 1 in embodiment P3 are as described above. In step 1 of embodiment P3, it is preferable to form the specific film by a coating method because it is easy to form a specific photosensitive film. Step 2 in embodiment P3 is a step in which a pattern exposure treatment and a development treatment are applied to the specific photosensitive film obtained in step 1 to form colored pixels. For the details of the pattern exposure treatment and development treatment, the method of step X2 described above can be used.

[0260] <Aspect P4> The method for manufacturing a color filter according to aspect P4 comprises step 1 and step 2 in that order. In step 1 of aspect P4, it is preferable to form the specific film by a dry film formation method because it is easy to remove a portion of the specific film in step 2. Step 2 in aspect P4 is a step of removing a portion of the specific film by irradiating the specific film with an electron beam and sublimating a portion of the specific film to form a colored pixel. As the electron beam irradiation method, known EB drawing patterning techniques can be used. If a portion of the specific film can be directly removed with a high-energy beam, i-rays, KrF excimer laser light (e.g., wavelength 248 nm), ArF excimer laser light (e.g., wavelength 193 nm), EUV (e.g., wavelength 3 to 15 nm), X-rays, soft X-rays, gamma rays, and synchrotron radiation may be used instead of electron beams.

[0261] <Aspect P5> The method for manufacturing a color filter according to aspect P5 comprises, in this order, step X3 of providing a photosensitive resin layer on a support before step 1, step X4 of applying a pattern exposure treatment and a development treatment to the photosensitive resin layer to form a pattern, step 1, and step 2.

[0262] Step X3 in embodiment P5 is the same as step X3 in embodiment P2 described above. Step X4 is a step of forming a pattern by applying a pattern exposure treatment and a development treatment to the photosensitive resin layer. The method of step X2 described above can be used as the pattern exposure treatment and development treatment method for the photosensitive resin layer.

[0263] Step 1 in embodiment P5 is a method for forming a specific film on a support having a pattern obtained in step X4. In step X4, a specific film is usually formed on areas of the support where no pattern is formed and on the pattern. The specific film in areas where no pattern is present and the specific film on the pattern are separated, and a portion of the specific film can be easily removed in step 2. Therefore, it is preferable that the thickness of the specific film be smaller than the thickness of the pattern formed in step X4. Specifically, for example, the thickness of the pattern can be 1.0 to 1.5 μm and the thickness of the specific film can be 0.2 to 1.0 μm.

[0264] Step 2 in embodiment P5 is a method for removing the pattern and a specific film on the pattern. A known resist stripping method can be used as the removal method. Specific examples of resist stripping methods include a method of bringing a stripping solution into contact with the pattern and dry etching, and from the viewpoint of simplicity, the method of bringing a stripping solution into contact with the pattern is preferred. By stripping the pattern, the pattern and the specific film on the pattern are selectively removed, and a colored pixel can be formed.

[0265] <Aspect P6> The method for manufacturing a color filter according to aspect P6 comprises a step X5 of forming a specific film on a substrate and a step X6 of transferring a part of the specific film onto a support using an electron beam. The substrate in step X5 is preferably transparent to electron beams. Specifically, resin substrates such as polycarbonate film, polyester film, and polyurethane film are preferred. As a method for forming the specific film on the substrate, the method of forming the specific film on a support in step 1 described above can be used.

[0266] Step X6 is a step of transferring a portion of the specific film to a support using an electron beam. The support is the support described in Step 1 above. More specifically, a method of transferring a portion of the specific film using an electron beam is to place the specific film formed on a substrate and the support facing each other, and irradiate the specific film with an electron beam from the substrate side. As a result, a portion of the specific film sublimes and is adsorbed onto the support, thereby forming colored pixels. It is also preferable that the support has an adsorption film on its outermost surface that adsorbs the components that form the colored pixels. Examples of the adsorption film include resin films such as polycarbonate film, polyester film, and polyurethane film.

[0267] When a color filter has multiple colored pixels, the color filter may be manufactured by repeatedly performing the above-described method for forming colored pixels (e.g., steps 1 and 2) multiple times. For example, after forming the first colored pixel by steps 1 and 2, the substrate on which the second colored pixel has been formed may be used as a support, and the green pixel may be formed by steps 1 and 2. Furthermore, when a color filter has multiple colored pixels, it may also be manufactured by combining different methods for forming colored pixels. For example, the first colored pixel may be formed by the method of embodiment P1, and the second colored pixel may be formed by the method of embodiment P2.

[0268] [Solid-State Image Sensor] The solid-state image sensor of the present invention includes this color filter. Examples of the solid-state image sensor of the present invention include having a plurality of photodiodes and a light-receiving element made of polysilicon or the like that constitute the light-receiving area of ​​a solid-state image sensor (CCD image sensor, CMOS image sensor, etc.) on a substrate, and having this color filter on the side of the substrate where the light-receiving element is formed (e.g., the part other than the light-receiving part and / or the color adjustment pixels, etc.) or on the opposite side of the formation surface. A device protective film (e.g., a resin film or a silicon nitride film) may be provided between the light-receiving element or the substrate and this color filter, and a configuration in which a light-collecting means (e.g., a microlens, etc.; the same applies hereinafter) is provided on the device protective film and below the color filter (on the side closer to the substrate), or a configuration in which the light-collecting means is provided on this color filter, etc. Examples of imaging devices having such a structure include the devices described in Japanese Patent Application Publication No. 2012-227478, Japanese Patent Application Publication No. 2014-179577 and International Publication No. 2018 / 043654. The imaging device equipped with the solid-state image sensor of the present invention can be used not only in digital cameras and electronic devices with imaging functions (such as mobile phones), but also in in-vehicle cameras and surveillance cameras.

[0269] [Image Display Devices] This color filter can also be applied to image display devices such as liquid crystal displays and organic electroluminescent (organic EL) displays. A specific form of the above-mentioned liquid crystal display device is, for example, a laminate containing, from the user's side, a polarizing plate / substrate / this color filter / transparent electrode layer / alignment film / liquid crystal layer / alignment film / transparent electrode layer / TFT (Thin Film Transistor) element / substrate / polarizing plate / backlight unit in this order. For definitions of image display devices and details of each image display device, see, for example, "Electronic Display Devices" (by Akio Sasaki, Kogyo Chosakai Co., Ltd., published in 1990) and "Display Devices" (by Yoshiaki Ibuki, Sangyo Tosho Co., Ltd., published in 1989). Furthermore, liquid crystal display devices are described, for example, in "Next-Generation Liquid Crystal Display Technology" (edited by Tatsuo Uchida, Kogyo Chosakai Co., Ltd., published in 1994). There are no particular restrictions on the liquid crystal display devices to which the present invention can be applied; for example, it can be applied to various types of liquid crystal display devices described in the above-mentioned "Next-Generation Liquid Crystal Display Technology".

[0270] The present invention will be described in more detail below based on examples. The materials, amounts used, proportions, processing content, and processing procedures shown in the following examples can be modified as appropriate without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be interpreted as being limited by the examples shown below.

[0271] [Dyes] The specific compounds used in each example are shown below. The parentheses after each compound name indicate the formula number to which the specific compound corresponds. For example, the compound labeled "1-B1, (1)" is specific compound 1-B1, which is a compound represented by formula (1).

[0272]

[0273] The dye compounds other than the specified compound used in each example and comparative example are listed below.

[0274]

[0275] [Evaluation] For each example and comparative example, the spectral characteristics were evaluated using a film containing a dye capable of forming colored pixels. The film in each example corresponds to the specific film described above. The film in each comparative example is a comparative film for comparison purposes.

[0276] [Manufacturing of Specific Film and Comparative Film] <Example 1-1> Specific compound 1-B1 was deposited onto a glass substrate to a thickness of 100 nm. Then, specific compound 3-G1 was deposited onto the film of specific compound 1-B1 to a thickness of 100 nm to manufacture a specific film for red pixel formation.

[0277] <Example 1-2> A specific film for red pixel formation was manufactured by co-depositing specific compound 1-B1 and specific compound 1-G1 onto a glass substrate using vacuum deposition in the ratios (converted to film thickness ratio) shown in the table below, to a film thickness of 200 nm.

[0278] <Example 2-4> A specific film for green pixel formation was manufactured by co-depositing specific compound 2B-4 and dye compound CR-2 on a glass substrate using vacuum deposition in the ratios (converted to film thickness ratio) shown in the table below, to a film thickness of 250 nm.

[0279] <Example 3-1> A specific film for blue pixel formation was manufactured by co-depositing specific compound 3G-2 and dye compound CR-2 on a glass substrate using vacuum deposition in the ratios (converted to film thickness ratio) shown in the table below, to a film thickness of 250 nm.

[0280] <Other Examples and Comparative Examples> The specific films of Examples 1-3 to 1-14 and Examples 2-1 to 2-3, and the comparative films of Comparative Examples 1-1 to 1-5, are manufactured using the same procedure as in Example 1-2, with the dyes and ratios used changed as shown in the table below. The specific film of Example 2-5 and the comparative films of Comparative Examples 2-1 to 2-3 are manufactured using the same procedure as in Example 2-4. The comparative films of Comparative Examples 3-1 to 3-2 are manufactured using the same procedure as in Example 3-1, with the dyes and ratios used changed as shown in the table below. Examples 1-1 to 1-14 and Comparative Examples 1-1 to 1-5 are films for red pixel formation, Examples 2-1 to 2-5 and Comparative Examples 2-1 to 2-3 are films for green pixel formation, and Examples 3-1 and Comparative Examples 3-1 to 3-2 are films for blue pixel formation.

[0281] [Evaluation of Spectral Characteristics] For the specific film of Example 1-1, the transmittance was measured for light at wavelengths of 450 nm (corresponding to blue light), 530 nm (corresponding to green light), and 650 nm (corresponding to red light). Figure 2 shows the transmission spectrum of the specific film of Example 1-1. The spectral characteristics were evaluated from the transmittance at each wavelength based on the following criteria. For red pixels, it is preferable that the transmittance at a wavelength of 650 nm is high, and the transmittance at wavelengths of 450 nm and 530 nm is low. In practical terms, it is preferable that the transmittance evaluation for each wavelength of light is "B" or higher, and it is more preferable that the transmittance evaluation for light at a wavelength of 650 nm is "A", and the transmittance evaluation for light at a wavelength of 450 nm and 530 nm is "B" or higher. For green pixels, it is preferable that the transmittance at a wavelength of 530 nm is high, and the transmittance at wavelengths of 450 nm and 650 nm is low. In practical terms, it is preferable that the transmittance evaluation for each wavelength of light is "B" or higher, and it is more preferable that the transmittance evaluation for light at a wavelength of 450 nm and light at a wavelength of 650 nm is "B" or higher, and the transmittance evaluation for light at a wavelength of 530 nm is "A". For blue pixels, it is preferable that the transmittance for light at a wavelength of 450 nm is high, and the transmittance for light at wavelengths of 530 nm and 650 nm is low. In practical terms, it is preferable that the transmittance evaluation for each wavelength of light is "B" or higher, and it is more preferable that the transmittance evaluation for light at a wavelength of 450 nm is "A", and it is more preferable that the transmittance evaluation for light at a wavelength of 450 nm is "A". The specific films of Examples 1-2 to 1-9, 2-1 to 2-3, and 3-1, and the comparative films of Comparative Examples 1-1 to 1-5, 2-1 to 2-3, and 3-1 to 3-2 are evaluated using the same procedure.

[0282] The evaluation criteria for each color pixel are as follows. For example, in the evaluation of a film for forming red pixels, the evaluation criteria for the red pixel row and the blue, green, and red light transmittance columns are used. For example, if the transmittance of the film for forming red pixels is 3% at a wavelength of 450 nm, 6.5% at a wavelength of 530 nm, and 97% at a wavelength of 650 nm, then the evaluation of the transmittance of light at a wavelength of 450 nm is "A", the evaluation of the transmittance of light at a wavelength of 530 nm is "B", and the evaluation of the transmittance of light at a wavelength of 650 nm is "A".

[0283]

[0284] [Results] The composition and evaluation of the dyes in each film are shown in the table below. The "Pixel Hue" column indicates whether each film is for forming red, green, or blue pixels. The "Ratio (Film Thickness Ratio)" column shows the usage ratio (film thickness ratio) of each dye in each film. For example, in Example 1-1, where dye 1 is 1-B1 and dye 2 is 1-G1, and the ratio is "1:1", the specific film contains specific compound 1-B1 and specific compound 1-G1 in a ratio of 1-B1:1-G1 = 1:1 (film thickness ratio). "Film Formation Method" is defined as "Lamination" when a film is manufactured by laminating films of each dye, "Co-deposition" when a film is formed by co-deposition of multiple dyes, and "Deposition" when a film is formed by depositing one type of dye.

[0285]

[0286] From the results shown in the table above, it can be confirmed that colored pixels containing the specific compound exhibit excellent spectral characteristics even in thin films. Furthermore, from a comparison between Examples 1-7 to 1-8 and Examples 1-1 to 1-6 and Examples 1-10 to 1-14, and from a comparison between Examples 2-4 to 2-5 and Examples 2-1 to 2-3, it can be confirmed that the effects of the present invention are superior when the colored pixel contains specific compound 2. From a comparison between Example 1-9 and Examples 1-7 to 1-8, it can be confirmed that the effects of the present invention are superior when the content of the specific compound in the colored pixel is 50% by volume or more relative to the total volume of the colored pixel. From a comparison between Example 2-3 and Examples 2-1 to 2-2 and Examples 2-4 to 2-5, it can be confirmed that the effects of the present invention are superior when the specific compound is at least one selected from the group consisting of specific compound 1, specific compound 2, and specific compound 4.

[0287] [Manufacturing of Color Filters] Color filters can be manufactured by following the procedure below.

[0288] [Manufacturing Example 1-1] A specific film having the same composition as in Example 2-1 described above is deposited on an 8-inch silicon wafer by co-evaporation to a thickness of 200 nm to form a specific film 1-1 for green pixel formation.

[0289] Next, compound (P-1) is deposited onto the obtained specific film 1-1 as a protective film to a thickness of 50 nm.

[0290]

[0291] A positive-type photoresist "FHi622BC" (manufactured by Fujifilm Electronic Materials Corporation) is applied to the protective film, pre-baked, and a photoresist layer with a thickness of 0.8 μm is formed.

[0292] Next, the photoresist layer was subjected to a 350 mJ / cm using an i-line stepper (manufactured by Canon Inc.). ２The pattern is exposed with the specified exposure dose, and then heated for 1 minute at a temperature where the temperature of the photoresist layer or the ambient temperature reaches 90°C. After that, development is performed for 1 minute with the developer "FHD-5" (manufactured by Fujifilm Electronic Materials Co., Ltd.), and then a post-bake treatment is performed at 110°C for 1 minute to form the resist pattern. The size of this resist pattern can be formed with a side length of 1.25 μm, taking into account the etching conversion difference (reduction in pattern width due to etching).

[0293] Next, using the obtained resist pattern as an etching mask, dry etching of specific film 1-1 is performed according to the following procedure. The first stage etching process is carried out using a dry etching apparatus (Hitachi High-Technologies Corporation, U-621). Subsequently, the second stage etching process and over-etching process are carried out in the same etching chamber.

[0294] After dry etching under the above conditions, the resist pattern is removed by stripping using the photoresist stripping solution "MS230C" (manufactured by Fujifilm Electronic Materials Corporation) for 120 seconds. Further washing with pure water and spin drying are performed. After that, a dehydration bake treatment is performed at 100°C for 2 minutes. As a result, the first colored pixel, green pixel 1-1, can be formed. The size of this green pixel is 1.2 μm.

[0295] Except for using the silicon wafer on which the above-mentioned green pixel 1-1 is formed as a substrate and co-depositing a specific film for forming red pixels having the same composition as in Example 1-2 described above, a second red pixel 1-1 can be formed as the main colored pixel by the same procedure. This makes it possible to manufacture the main color filter 1-1 having the green pixel 1-1 and the red pixel 1-1. The green pixel 1-1 and the red pixel 1-1 in the main color filter 1-1 exhibit spectral characteristics equivalent to those of the specific film in Example 2-1 and the specific film in Example 1-2 described above, respectively.

[0296] [Manufacturing Example 2-1] A red, green, and blue stripe pattern can be produced by the following procedure. First, a photoresist is applied to a transparent glass plate, and a stripe-shaped photoresist pattern with an aperture width of 20 μm and a pitch of 60 μm is formed by pattern exposure and development. Next, a specific film 2-1 for forming blue pixels, having the same composition as in Example 3-1 described above, is deposited on the photoresist pattern by co-evaporation to a film thickness of 2000 Å. Then, the photoresist pattern and the specific film 2-1 on the photoresist pattern are removed by a stripping process to form stripe-shaped blue pixels 2-1.

[0297] Except for using a specific film with the same composition as in Example 2-1 described above as the specific film for forming green pixels, and a specific film with the same composition as in Example 1-2 described above as the specific film for forming red pixels, the same procedure is used to sequentially form green pixels and red pixels, thereby obtaining a color filter 2-1 in which blue pixels 2-1, green pixels 2-1, and red pixels 2-1 are arranged in a stripe pattern. The blue pixels 2-1, green pixels 2-1, and red pixels 2-1 in this color filter 2-1 exhibit spectral characteristics equivalent to those of the specific film in Example 3-1, the specific film in Example 2-1, and the specific film in Example 1-2 described above, respectively.
