[0058] (Drive board 11)

[0059] The driving board 11 is a so-called backplane and can drive a plurality of light emitting elements 12W. The driving board 11 includes, for example, a substrate 111 and an insulating layer 112 in this order.

[0060] A plurality of driving circuits, a plurality of wirings (all not shown), etc. may be arranged on the first surface of the substrate 111. The substrate 111 may include, for example, a semiconductor (such as a transistor) that is easily formed, or may include glass or resin with low moisture permeability and oxygen permeability. Specifically, the substrate 111 may be a semiconductor substrate, a glass substrate, a resin substrate, etc. The semiconductor substrate may include, for example, amorphous silicon, polycrystalline silicon, single crystal silicon, etc. The glass substrate may include, for example, high strain point glass, soda glass, borosilicate glass, forsterite, lead glass, quartz glass, etc. For example, the resin substrate may include at least one selected from the group including polymethyl methacrylate, polyvinyl alcohol, polyvinyl phenol, polyether sulfone, polyimide, polycarbonate, polyethylene terephthalate, polyethylene naphthalate, etc.

[0063] (Light emitting element 12W)

[0064] The light emitting element 12W can emit white light under the control of a driving circuit or the like. The light emitting element 12W is an OLED element. The OLED element can be a micro-OLED (M-OLED) element. The light emitting element 12W is included in the sub-pixels 10R, 10G, and 10B.

[0065] A plurality of light emitting elements 12W are two-dimensionally arranged on the first surface of the driving board 11 in a predetermined arrangement pattern. The prescribed arrangement pattern is as described for the prescribed arrangement pattern of the plurality of sub-pixels 10. The light emitting element 12W includes a first electrode 121, an OLED layer 122, and a second electrode 123. The first electrode 121, the OLED layer 122, and the second electrode 123 are laminated on the first surface of the driving board 11.

[0066] (First Electrode 121)

[0067] The first electrode 121 is provided on the second surface side of the OLED layer 122. The first electrode 121 is provided individually in the plurality of light emitting elements 12W in the effective pixel region RE1. That is, the first electrode 121 is separated between the light emitting elements 12W adjacent in the in-plane direction in the effective pixel region RE1. The first electrode 121 is an anode. When a voltage is applied between the first electrode 121 and the second electrode 123, holes are injected from the first electrode 121 into the OLED layer 122.

[0068] The first electrode 121 may be composed of, for example, a metal layer, or may be composed of a metal layer and a transparent conductive oxide layer. In the case where the first electrode 121 is composed of a metal layer and a transparent conductive oxide layer, from the viewpoint of allowing a layer having a high work function to be adjacent to the OLED layer 122, the transparent conductive oxide layer is preferably provided on the OLED layer 122 side.

[0069] The metal layer also has a function as a reflective layer that reflects light generated in the OLED layer 122. For example, the metal layer includes at least one metal element selected from the group consisting of chromium (Cr), gold (Au), platinum (Pt), nickel (Ni), copper (Cu), molybdenum (Mo), titanium (Ti), tantalum (Ta), aluminum (Al), magnesium (Mg), iron (Fe), tungsten (W), and silver (Ag). The metal layer may contain at least one of the above metal elements as a constituent element of an alloy. Specific examples of the alloy include aluminum alloys and silver alloys. Specific examples of the aluminum alloy include, for example, AlNd and AlCu.

[0070] A base layer (not shown) may be disposed adjacent to the second surface side of the metal layer. The base layer is used to improve the crystal orientation characteristics of the metal layer during the formation of the metal layer. The base layer includes, for example, at least one metal element selected from the group including titanium (Ti) and tantalum (Ta). The base layer may include the above-mentioned at least one metal element as a constituent element of the alloy.

[0071] The transparent conductive oxide layer includes a transparent conductive oxide. For example, the transparent conductive oxide includes at least one selected from the group consisting of an indium-containing transparent conductive oxide (hereinafter, referred to as "indium-based transparent conductive oxide"), a tin-containing transparent conductive oxide (hereinafter, referred to as "tin-based transparent conductive oxide"), and a zinc-containing transparent conductive oxide (hereinafter, referred to as "zinc-based transparent conductive oxide").

[0072] Indium-based transparent conductive oxides include, for example, indium tin oxide (ITO), indium zinc oxide (IZO), indium gallium oxide (IGO), indium gallium zinc oxide (IGZO), or fluorine-doped indium oxide (IFO). Among these transparent conductive oxides, indium tin oxide (ITO) is particularly preferred. This is because indium tin oxide (ITO) functionally has a particularly low barrier for hole injection into the OLED layer 122, thereby being able to particularly reduce the driving voltage of the display device 101. Tin-based transparent conductive oxides include, for example, tin oxide, antimony-doped tin oxide (ATO), or fluorine-doped tin oxide (FTO). Zinc-based transparent conductive oxides include, for example, zinc oxide, aluminum-doped zinc oxide (AZO), boron-doped zinc oxide, or gallium-doped zinc oxide (GZO).

[0073] (OLED layer 122)

[0074] The OLED layer 122 may emit white light. The OLED layer 122 is disposed between the first electrode 121 and the second electrode 123. The OLED layer 122 is connected between adjacent light emitting elements 12W in the effective pixel region R1, and is shared by a plurality of light emitting elements 12W in the effective pixel region R1.

[0075] The OLED layer 122 may be an OLED layer including a single-layer light-emitting unit, may be an OLED layer including two-layer light-emitting units (stacked structure), or may be an OLED layer having other structures. The OLED layer including a single-layer light-emitting unit has, for example, a hole injection layer, a hole transport layer, a red light-emitting layer, a light-emitting separation layer, a blue light-emitting layer, a green light-emitting layer, an electron transport layer, and an electron injection layer stacked in this order from the first electrode 121 toward the second electrode 123. The OLED layer including two-layer light-emitting units has, for example, a hole injection layer, a hole transport layer, a blue light-emitting layer, an electron transport layer, a charge generation layer, a hole transport layer, a yellow light-emitting layer, an electron transport layer, and an electron injection layer stacked in this order from the first electrode 121 toward the second electrode 123.

[0076] The hole injection layer is used to improve the hole injection efficiency into each light-emitting layer and suppress leakage. The hole transport layer is used to improve the hole transport efficiency to each light-emitting layer. The electron injection layer is used to improve the electron injection efficiency into each light-emitting layer. The electron transport layer is used to improve the electron transport efficiency to each light-emitting layer. The luminescence separation layer is a layer for adjusting the carrier injection into each light-emitting layer, and the luminescence balance of each color is adjusted by injecting electrons or holes into each light-emitting layer through the luminescence separation layer. The charge generation layer provides electrons and holes to the two light-emitting layers sandwiched between the charge generation layers.

[0077] In response to applying an electric field to each of the red, green, blue and yellow light-emitting layers, recombination occurs between holes injected from the first electrode 121 or the charge generation layer and electrons injected from the second electrode 123 or the charge generation layer, and red, green, blue and yellow light are emitted.

[0078] (Second Electrode 123)

[0079] The second electrode 123 is provided on the first surface side of the OLED layer 122. The second electrode 123 is connected between adjacent light emitting elements 12W in the effective pixel region R1, and is shared by a plurality of light emitting elements 12W in the effective pixel region R1. The second electrode 123 is a cathode. When a voltage is applied between the first electrode 121 and the second electrode 123, holes are injected from the second electrode 123 into the OLED layer 122. The second electrode 123 has translucency for each light emitted from the OLED layer 122. The second electrode 123 is preferably a transparent electrode having transparency to visible light. In this specification, visible light refers to light in a wavelength range of 360 nm or more and 830 nm.

[0080] In order to improve the luminous efficiency, the second electrode 123 is preferably composed of a material having as high a translucency as possible and a small work function. The second electrode 123 is composed of, for example, at least one of a metal layer or a transparent conductive oxide layer. More specifically, the second electrode 123 is composed of a single-layer film of a metal layer or a transparent conductive oxide layer, or a laminated film of a metal layer and a transparent conductive oxide layer. In the case where the second electrode 123 is composed of a laminated film, the metal layer may be provided on the OLED layer 122 side, or the transparent conductive oxide layer may be provided on the OLED layer 122 side, but from the viewpoint of allowing a layer having a low work function to be adjacent to the OLED layer 122, the metal layer is preferably provided on the OLED layer 122 side.

[0081] For example, the metal layer includes at least one metal element selected from the group consisting of magnesium (Mg), aluminum (Al), silver (Ag), calcium (Ca) and sodium (Na). The metal layer may include the at least one metal element as a constituent element of an alloy. Specific examples of the alloy include MgAg alloy, MgAl alloy, AlLi alloy, etc. The transparent conductive oxide layer includes a transparent conductive oxide. As the transparent conductive oxide, a material similar to the transparent conductive oxide of the above-mentioned first electrode 121 can be exemplified.

[0082] (Contact part 124)

[0083] The contact portion 124 is provided on the first surface of the driving board 11 in the peripheral region RE2. The contact portion 124 is an auxiliary electrode that connects the second electrode 123 to a substrate wiring or the like (not shown). The first surface of the contact portion 124 is electrically connected to the peripheral edge portion of the second surface of the second electrode 123. On the other hand, the second surface of the contact portion 124 is connected to the substrate wiring or the like via a plurality of contact plugs or the like. In this specification, the peripheral edge portion of the second surface refers to a region having a predetermined width inward from the peripheral edge of the second surface.

[0084] The contact portion 124 may have a closed loop shape surrounding the entire periphery of the effective pixel region RE1 in a plan view, or may have a partially segmented loop shape partially surrounding the periphery of the effective pixel region RE1. In this specification, a plan view refers to a plan view when an object is viewed from a front direction DZ.

[0085] For example, the contact portion 124 is composed of at least one of a metal layer or a metal oxide layer. More specifically, for example, the contact portion 124 is composed of a single layer film of a metal layer or a metal oxide layer, or a laminated film of a metal layer and a metal oxide layer. The configuration of the contact portion 124 is preferably similar to the first electrode 121. In this case, since the contact portion 124 can be formed simultaneously with the first electrode 121, the manufacturing process of the display device 101 can be simplified.

[0086] As constituent materials of the contact portion 124, materials similar to those of the first electrode 121 can be exemplified. Specifically, as constituent materials of the metal layer and the metal oxide layer of the contact portion 124, materials similar to those of the first electrode 121 can be exemplified, respectively.

[0087] (Insulation layer 13)

[0088] The insulating layer 13 is provided in a portion between the separated first electrodes 121 on the first surface of the driving board 11. The insulating layer 13 insulates the adjacent first electrodes 121. The insulating layer 13 has a plurality of openings. Each of the plurality of openings is provided for a corresponding one of the light emitting elements 12W. More specifically, each of the plurality of openings is provided on the first surface (the surface on the OLED layer 122 side) of each of the first electrodes 121. The first electrode 121 and the OLED layer 122 are in contact with each other through the openings.

[0089] The insulating layer 13 may also be provided between the first electrode 121 and the contact portion 124 in the first surface of the driving board 11. The insulating layer 13 may insulate the first electrode 121 from the contact portion 124. The insulating layer 13 may also be provided on a portion outside the contact portion 124 in the first surface of the driving board 11.

[0090] The insulating layer 13 may be an organic insulating layer, an inorganic insulating layer, or a multilayer body including these. For example, the organic insulating layer includes at least one selected from the group including polyimide resins, acrylic resins, novolac resins, etc. For example, the inorganic insulating layer includes at least one selected from the group including silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiOxNy), etc.

[0091] (Protective layer 14)

[0092] The protective layer 14 is disposed on the first surface of the driving board 11 to cover the plurality of light emitting elements 12W. The protective layer 14 has translucency relative to the light emitted by the light emitting elements 12W. The protective layer 14 is preferably transparent to visible light. The protective layer 14 can protect the plurality of light emitting elements 12W, etc. The protective layer 14 shields the light emitting elements 12W from the outside air and inhibits moisture in the outside environment from penetrating into the light emitting elements 12W. In addition, in the case where the second electrode 123 is composed of a metal layer, the protective layer 14 may have a function of inhibiting oxidation of the metal layer.

[0093] The protective layer 14, for example, includes an inorganic material or a polymer resin, both of which have low hygroscopicity. The protective layer 14 may have a single-layer structure or a multilayer structure. In the case where the thickness of the protective layer 14 increases, a multilayer structure is preferred. This is to alleviate the internal stress of the protective layer 14. For example, the inorganic material includes at least one selected from the group including silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiOxNy), titanium oxide (TiOx), aluminum oxide (AlOx), etc. For example, the polymer resin includes at least one selected from the group including thermosetting resins, ultraviolet curing resins, etc. Specifically, for example, the polymer resin includes at least one selected from the group including acrylic resins, polyimide resins, phenolic varnish resins, epoxy resins, norbornene resins, polyparaxylene resins, etc.

[0094] (Protective layer 15)

[0095] The protective layer 15 is disposed on the first surface of the protective layer 14. The protective layer 15 has translucency to the light emitted by the light emitting element 12W. The protective layer 15 is preferably transparent to visible light. The protective layer 15 can protect a plurality of light emitting elements 12W, etc. The protective layer 15 shields the light emitting element 12W from the outside air and suppresses moisture from penetrating into the light emitting element 12W from the outside environment.

[0096] The protective layer 15 contains, for example, a metal oxide. The protective layer 15 is preferably composed of a single-layer deposit. More specifically, the protective layer 15 is preferably an atomic layer deposition (ALD) layer. When the protective layer 15 is composed of a single-layer deposit, the effect of the protective layer 15 in suppressing moisture penetration can be improved. The protective layer 15 contains, for example, aluminum oxide (AlOx) or titanium oxide (TiOx).

[0097] (Planarization layer 16)

[0098] The planarization layer 16 covers the first surface of the protective layer 15 and forms a flat surface above the first surface of the protective layer 15. The planarization layer 16 includes, for example, an inorganic material or a polymer resin. As the inorganic material, a material similar to the inorganic material of the protective layer 14 can be exemplified. As the polymer resin, a material similar to the polymer resin of the protective layer 14 can be exemplified.

[0099] (Color filter 17)

[0100] Figure 41 is a plan view of the color filter 17. The color filter 17 is arranged above the plurality of light emitting elements 12W. More specifically, the color filter 17 is arranged on the first surface of the planarization layer 16 in the effective pixel region RE1. The color filter 17 is, for example, an on-chip color filter (OCCF). The color filter 17 includes, for example, a plurality of red filter sections 17FR, a plurality of green filter sections 17FG, and a plurality of blue filter sections 17FB. Note that in the following description, in the case where the red filter section 17FR, the green filter section 17FG, and the blue filter section 17FB are not particularly distinguished from each other, the red filter section 17FR, the green filter section 17FG, and the blue filter section 17FB will be collectively referred to as the filter section 17F.

[0101] The plurality of filter sections 17F are two-dimensionally arranged on the first surface of the planarization layer 16 in a prescribed arrangement pattern. The prescribed arrangement pattern is as described for the prescribed arrangement pattern of the plurality of sub-pixels 10. Each filter section 17F is disposed above one light emitting element 12W. The red filter section 17FR and the light emitting element 12W together constitute the sub-pixel 10R, the green filter section 17FG and the light emitting element 12W together constitute the sub-pixel 10G, and the blue filter section 17FB and the light emitting element 12W together constitute the sub-pixel 10B.

[0102] The red filter 17FR can transmit red light in the white light emitted from the light emitting element 12W and absorb light other than red light. The green filter 17FG can transmit green light in the white light emitted from the light emitting element 12W and absorb light other than green light.

The light shielding layer 17BK is preferably provided above the contact portion 124 and covers the contact portion 124. The light shielding layer 17BK can absorb and shield external light (visible light) incident on the peripheral region RE2. Therefore, reflection of external light caused by the contact portion 124 and the like can be suppressed.

[0106] The light shielding layer 17BK may have a closed loop shape surrounding the entire periphery of the effective pixel region RE1 in a plan view, or may have a partially divided loop shape partially surrounding the periphery of the effective pixel region RE1 .

[0107] The light shielding layer 17BK preferably includes a red filter section 17FR and a blue filter section 17FB. Since the light shielding layer 17BK has such a configuration, the light shielding layer 17BK can be formed simultaneously in the process of forming the color filter 17. However, the configuration of the light shielding layer 17BK is not limited thereto, and may be, for example, a light shielding layer containing a black light absorbing material. For example, the black light absorbing material contains at least one selected from a group including a black resin material and a black metal-containing material. For example, the black resin material includes a carbon material such as carbon black. The black resin material may contain, for example, a black resist, etc. The black metal-containing material includes, for example, titanium nitride (TiNx), etc.

[0108] (Near infrared absorption layer 18)

[0109] The near-infrared absorption layer 18 can absorb near-infrared rays. Therefore, the reflection of near-infrared rays can be suppressed in the display device 101. In this specification, near-infrared rays refer to light (electromagnetic waves) having a wavelength of more than 700nm and less than 2500nm. The near-infrared absorption layer 18 is arranged in the effective pixel area RE1 and the peripheral area RE2 located around the effective pixel area RE1. Therefore, in both the effective pixel area RE1 and the peripheral area RE2, the reflection of near-infrared rays can be suppressed. The near-infrared absorption layer 18 is arranged inside the cover glass 20. Therefore, the degradation of the near-infrared absorption layer 18 can be suppressed.

[0110] The near infrared absorption layer 18 preferably includes photoresist and a near infrared absorption material. Since the near infrared absorption layer 18 includes the photoresist, the pattern part 181 having a desired pattern can be easily formed by a photolithography technique.

[0111] The near infrared absorption material includes, for example, at least one selected from the group including an organic compound and a metal complex. More specifically, the near infrared absorption material includes, for example, at least one selected from the group including a diimmonium compound, an ammonium compound, a phthalocyanine compound, an organic metal complex, a cyanine compound, an azo compound, a polymethine compound, a quinone compound, a diphenylmethane compound, a triphenylmethane compound, a metal oxide, etc. The metal oxide includes, for example, at least one selected from the group including tungsten oxide, a composite tungsten oxide, etc. The near infrared absorption material may be a particle.

[0112] The near infrared absorption layer 18 preferably includes a pattern portion 181 and a non-pattern portion 182 .

[0113] (Pattern section 181)

[0114] The pattern portion 181 is provided on the first surface of the color filter 17 in the effective pixel region RE1. Since the near infrared absorption layer 18 has the pattern portion 181 in the effective pixel region RE1, absorption of emitted light by the near infrared absorption layer 18 can be suppressed. Therefore, a reduction in brightness of the display device 101 due to the near infrared absorption layer 18 can be suppressed.

[0115] For example, the pattern portion 181 may have a stripe shape (see Figure 5 A), lattice shape (see Figure 5 B and Figure 6 A) or checkered pattern shape ( Figure 6 B) or may have other patterns. The pattern portion 181 has one or more near-infrared absorption portions 181M and a plurality of opening portions 181N. The plurality of opening portions 181N are two-dimensionally arranged on the first surface of the color filter 17 in a predetermined arrangement pattern. The opening portion 181N is preferably arranged at the position of the filter portion 17F of at least one color among the filter portions 17FR, 17FG, and 17FB of multiple colors (three colors). The near-infrared absorption portion 181M is preferably arranged at the position of the filter portion 17F other than the filter portion 17F of at least one color.

[0116] (Arrangement in sub-pixel units)

[0117] like Figure 5 A. Figure 5 B and Figure 6 As shown in FIG. 1A , the opening portion 181N may be provided with a sub-pixel 10 as a minimum unit, and the near-infrared absorption portion 181M may be provided with a sub-pixel 10 as a minimum unit. More specifically, the opening portion 181N may be provided at the position of a sub-pixel 10 of one prescribed color among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M may be provided at the position of sub-pixels 10 of two colors other than the sub-pixel 10 of the one prescribed color. Alternatively, the opening portion 181N may be provided at the position of sub-pixels 10 of two prescribed colors among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M may be provided at the position of sub-pixels 10 of one color other than the sub-pixels 10 of the two prescribed colors.

[0118] Examples of patterns in which the opening portion 181N is provided at the position of a sub-pixel 10 of one specified color among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the position of sub-pixels 10 of two colors other than the sub-pixel 10 of the specified color include the following patterns (1), (2), and (3).

[0120] Pattern (2): The opening portion 181N is provided at the position of the sub-pixel 10G among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the positions of the sub-pixels 10R and 10B among the sub-pixels 10R, 10G, and 10B (see FIG. 1 ). Figure 6 A).

[0121] Pattern (3): the opening portion 181N is provided at the position of the sub-pixel 10B among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the positions of the sub-pixels 10R and 10G among the sub-pixels 10R, 10G, and 10B.

[0122] From the viewpoint of suppressing a decrease in brightness caused by the near-infrared absorbing portion 181M, the pattern (1) is preferable among the pattern (1), the pattern (2), and the pattern (3).

[0123] Examples of patterns in which the opening portion 181N is provided at the position of a sub-pixel 10 of two specified colors among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the position of a sub-pixel 10 of a color other than the sub-pixels 10 of the two specified colors include the following patterns (4), (5), and (6).

[0124] Pattern (4): the opening portion 181N is provided at the position of the sub-pixels 10G and 10B among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the position of the sub-pixel 10R among the sub-pixels 10R, 10G, and 10B.

[0125] Pattern (5): The opening portion 181N is provided at the position of the sub-pixels 10R and 10B among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the position of the sub-pixel 10G among the sub-pixels 10R, 10G, and 10B.

[0126] Pattern (6): The opening portion 181N is provided at the position of the sub-pixels 10R and 10G among the sub-pixels 10R, 10G, and 10B, and the near-infrared absorption portion 181M is provided at the position of the sub-pixel 10B among the sub-pixels 10R, 10G, and 10B (see Figure 5 A).

[0127] From the viewpoint of suppressing a decrease in brightness caused by the near-infrared absorption portion 181M, pattern (5) and pattern (6) are preferred among pattern (4), pattern (5) and pattern (6).

[0128] (Layout in pixels)

[0129] like Figure 6 B, the opening portion 181N may be provided with a pixel 10Px as a minimum unit, and the near infrared absorption portion 181M may be provided with a pixel 10Px as a minimum unit. A plurality of near infrared absorption portions 181M and a plurality of opening portions 181N may be arranged in two dimensions. For example, the near infrared absorption portion 181M and the opening portion 181N may be alternately arranged in a first direction (e.g., a horizontal direction DX) and alternately arranged in a second direction (e.g., a vertical direction DY).

[0130] (Non-pattern portion 182)

[0131] The non-pattern portion 182 is a layer without a pattern, as shown in the pattern portion 181. The non-pattern portion 182 is provided on the first surface of the protective layer 19 in the peripheral region RE2. That is, the non-pattern portion 182 is provided above the light shielding layer 17BK in the peripheral region RE2. Since the near-infrared absorption layer 18 has the non-pattern portion 182 in the peripheral region RE2, the near-infrared rays incident to the peripheral region RE2 can be absorbed. Thus, the effect of suppressing the reflection of the near-infrared rays in the display device 101 can be further improved.

[0132] The non-pattern portion 182 may have a closed loop shape surrounding the entire periphery of the effective pixel region RE1 in a plan view, or may have a partially divided loop shape partially surrounding the periphery of the effective pixel region RE1 .

[0133] (Protective layer 19)

[0134] The protective layer 19 covers and protects the color filter 17, the pattern portion 181, the light shielding layer 17BK, etc. The protective layer 19 may also serve as an adhesive layer for bonding the cover glass 20 and the driving board 11, and each member such as the plurality of light emitting elements 12W is provided on the first surface.

[0135] The protective layer 19 has translucency with respect to the light emitted from the light emitting element 12W. The protective layer 19 preferably has transparency with respect to visible light. The protective layer 19 contains, for example, at least one selected from the group consisting of a thermosetting resin, an ultraviolet curing resin, a thermosetting resin, and the like. Note that the protective layer 19 may contain a curing resin other than a thermosetting resin and an ultraviolet curing resin.

[0136] (Cover glass 20)

[0137] The cover glass 20 is disposed on the first surface of the protective layer 19 and the first surface of the non-pattern portion 182. The cover glass 20 seals each component such as the plurality of light emitting elements 12W disposed on the first surface of the driving board 11. The cover glass 20 has translucency with respect to the light emitted from the light emitting elements 12W. The cover glass 20 is preferably transparent to visible light. The cover glass 20 is, for example, a glass substrate.

[0138] (Translucent Properties of Color Filter 17 and Near Infrared Absorption Layer 18)

[0139] Figure 7 17FG, the blue filter 17FB, and the near-infrared absorption layer 18. The near-infrared absorption layer 18 has a characteristic of absorbing only electromagnetic waves in the near-infrared region or a characteristic of absorbing only electromagnetic waves in the near-infrared region and a wavelength range longer than this region. Figure 7 As shown, generally, the near-infrared absorption layer has absorbability in the visible light wavelength range shorter than the near-infrared region, particularly in the red light wavelength range. Therefore, the brightness performance of the display device 101 can be changed according to the position of the opening 181N of the pattern portion 181 of the near-infrared absorption layer 18. Therefore, it is preferred that the near-infrared absorption layer 18 has the pattern portion 181 in the effective pixel region RE1, and the pattern portion 181 has the opening 181N at least at the position of the sub-pixel 10R (that is, at least at the position of the red filter portion 17FR). As a specific pattern of the pattern portion 181, as described above, pattern (1), pattern (5) or pattern (6) is preferred.

[0140] [Method of Manufacturing Display Device 101]

[0141] Hereinafter, an example of a method for manufacturing the display device 101 according to one embodiment will be described.

[0142] (Process of Forming First Electrode 121 and Contact Portion 124)

[0143] First, a metal layer and a metal oxide layer are sequentially formed on the first surface of the driving board 11 by, for example, sputtering, and then patterned using, for example, photolithography and etching techniques. Thus, a plurality of first electrodes 121 and contact portions 124 are formed on the first surface of the driving board 11.

[0144] (Process of Forming Insulating Layer 13)

[0145] Next, an insulating layer 13 is formed on the first surface of the driving board 11 by, for example, a chemical vapor deposition (CVD) method to cover the plurality of first electrodes 121 and the contact portion 124. Next, an opening portion is formed in a portion of the insulating layer 13 located on the first surface of each first electrode 121 and a portion located on the first surface of the contact portion 124 by, for example, a photolithography technique and a dry etching technique.

[0146] (Process of Forming OLED Layer 122)

[0147] Next, a hole transport layer, a red light-emitting layer, a light-emitting separation layer, a blue light-emitting layer, a green light-emitting layer, an electron transport layer and an electron injection layer are stacked in sequence on the first surface of multiple first electrodes 121 and the first surface of the driving plate 11 by, for example, a vapor deposition method, thereby forming an OLED layer 122.

[0148] (Process of Forming Second Electrode 123)

[0149] Next, the second electrode 123 is formed on the first surface of the OLED layer 122 and the first surface of the contact portion 124 by, for example, vapor deposition or sputtering. Thus, a plurality of light emitting elements 12W are formed on the first surface of the driving board 11, and the peripheral edge portion of the second surface of the second electrode 123 is connected to the contact portion 124.

[0150] (Process of Forming Protective Layer 14)

[0151] Next, the protective layer 14 is formed on the first surface of the second electrode 123 by, for example, a CVD method or a vapor deposition method.

[0152] (Process of Forming Protective Layer 15)

[0153] Next, the protective layer 15 is formed on the first surface of the protective layer 14 by, for example, atomic layer deposition (ALD).

[0154] (Process for Forming the Planarization Layer 16)

[0155] Next, the planarization layer 16 is formed on the first surface of the protective layer 15 by, for example, a CVD method or a vapor deposition method.

[0156] (Process of Forming Color Filter 17 and Light Shielding Layer 17BK)

[0157] Next, a coloring composition for forming a green filter is applied to the first surface of the planarization layer 16, and after pattern exposure by ultraviolet irradiation through a photomask, development is performed to form a green filter 17FG. Next, a coloring composition for forming a red filter is applied to the first surface of the planarization layer 16, and after pattern exposure by ultraviolet irradiation through a photomask, development is performed to form a red filter 17FR. Next, a coloring composition for forming a blue filter is applied to the first surface of the planarization layer 16, and after pattern exposure by ultraviolet irradiation through a photomask, development is performed to form a blue filter 17FB. Thus, the color filter 17 and the light shielding layer 17BK are formed on the first surface of the planarization layer 16.

[0158] (Process of Forming Pattern Section 181)

[0159] Next, a composition for forming a near infrared absorption layer is applied on the first surface of the color filter 17, and after pattern exposure with ultraviolet irradiation through a photomask, development is performed to form a pattern portion 181. As the composition for forming the near infrared absorption layer, for example, a photoresist to which a near infrared absorption material is added is used.

[0160] (Sealing treatment)

[0161] Next, a composition for forming a near-infrared absorption layer is applied to the peripheral edge portion of the second surface of the cover glass 20 and irradiated with ultraviolet rays to form a non-pattern portion 182. Next, a curing resin is applied to the first surface of the planarization layer 16 to cover the pattern portion 181 and the light shielding layer 17BK. For example, the curing resin contains at least one selected from a group including a thermosetting resin, an ultraviolet curing resin, and the like. Next, the cover glass 20 is placed on the curable resin so that the second surface of the cover glass 20 faces the curable resin. Next, for example, the curing resin is cured by at least one of a heat treatment and an ultraviolet irradiation treatment to form a protective layer 19. Therefore, various components such as a driving board 11 of a plurality of light-emitting elements 12W are provided on the first surface, and the cover glass 20 is bonded together by the protective layer 19. Note that the curing method of the curing resin is not limited to the heat treatment and the ultraviolet irradiation treatment, and may be a curing method other than the heat treatment and the ultraviolet irradiation treatment. Through the above process, a Figure 3 The display device 101 shown in FIG.

[0162] [Function and Effect]

[0163] In the display device 101 according to one embodiment, the near infrared absorption layer 18 is provided in the effective pixel region RE1 and the peripheral region RE2 located around the effective pixel region RE1. Therefore, in both the effective pixel region RE1 and the peripheral region RE2, the reflection of near infrared rays can be suppressed. Therefore, when the display device 101 is provided in the goggle device, the generation of stray light of near infrared rays can be suppressed.

[0164] The near infrared absorption layer 18 has the pattern portion 181 in the effective pixel region RE1. Therefore, it is possible to suppress the reduction in brightness of the display device 101 due to the provision of the near infrared absorption layer 18. In addition, by adjusting the pattern of the pattern portion 181, a desired light transmittance can be obtained. Therefore, it is possible to suppress the reduction in the degree of freedom in designing the display device 101 due to the provision of the near infrared absorption layer 18.

[0165] As a display device capable of suppressing near-infrared reflection, a unit-type display device in which a near-infrared absorbing film is bonded to a display surface can be conceived. However, the process of bonding the near-infrared absorbing film to the first surface (display surface) may lead to an increase in the cost of the display device. On the other hand, the display device 101 according to one embodiment is an in-unit display device including a near-infrared absorbing layer 18. Therefore, the process of bonding the near-infrared absorbing film to the display surface may not be provided. Therefore, the increase in the cost of the display device 101 caused by adding a function of suppressing near-infrared reflection can be suppressed.

[0181] In Table 1, the meanings of the numerical values ​​1 to 4 in the brightness characteristics are as follows.

[0182] Reference numerals 1 to 4 denote the order of brightness height, and the brightness increases in the order of 1, 2, 3, and 4.

[0183] In Table 1, the meanings of the numerical values ​​1 to 4 in the IR cutoff function are as follows.

[0184] Numerical values ​​1 to 4 represent the order of the height of the IR cutoff function (the height of the near-infrared absorption ability), and it is assumed that the IR cutoff function is higher in the order of 1, 2, 3, and 4.

[0185] As can be seen from Table 1, from the viewpoint of achieving both brightness characteristics and IR cut-off function, the near-infrared absorption layer on the color filter preferably has a pattern.

[0299] <5 Examples of Resonator Structures>

[0300] The pixel used in the display device according to the present disclosure described above may have a resonator structure that resonates light generated in the light emitting element. Hereinafter, the resonator structure will be described with reference to the accompanying drawings. In addition, in the following description, the first surface of each layer may be referred to as an upper surface.

[0301] (Resonator Structure: First Example)

[0302] Fig.17 A is a schematic cross-sectional view for explaining a first example of a resonator structure. In the following description, the light-emitting elements provided corresponding to the sub-pixels 10R, 10G, and 10B are collectively referred to as light-emitting elements 12 unless otherwise specifically distinguished. In the case of distinguishing the light-emitting elements provided corresponding to the sub-pixels 10R, 10G, and 10B, they may be referred to as light-emitting elements 12R, 12G, and 12B. The portions of the OLED layer 122 corresponding to the sub-pixels 10R, 10G, and 10B may be referred to as OLED layers 122R, OLED layers 122G, and OLED layers 122B, respectively.

[0303] In the first example, the first electrode 121 is formed to have a common film thickness in each light emitting element 12. The same applies to the second electrode 123.

[0304] The reflector 71 is disposed below the first electrode 121 of the light emitting element 12, with the optical adjustment layer 72 interposed therebetween. A resonance structure that causes resonance of light generated by the OLED layer 122 is formed between the reflector 71 and the second electrode 123. In the following description, the optical adjustment layers 72 disposed corresponding to the sub-pixels 10R, 10G, and 10B may be referred to as optical adjustment layers 72R, 72G, and 72B, respectively.

[0305] The reflector 71 is formed to have a common film thickness in each light emitting element 12. The film thickness of the optical adjustment layer 72 is different depending on the color to be displayed by the pixel. In addition, since the film thicknesses of the optical adjustment layers 72R, 72G, and 72B are different, the optical distance that makes the wavelength resonance of light optimal can be set according to the color to be displayed.

[0306] exist Fig.17 In the example shown in FIG. 1A, the upper surfaces of the reflectors 71 in the light emitting elements 12R, 12G, and 12B are arranged to be aligned. As described above, since the film thickness of the optical adjustment layer 72 is different depending on the color to be displayed by the pixel, the position of the upper surface of the second electrode 123 is different depending on the type of the light emitting elements 12R, 12G, and 12B.

[0307] The reflector 71 may include, for example, a metal such as aluminum (Al), silver (Ag), or copper (Cu), or an alloy containing these metals as a main component.

[0308] The optical adjustment layer 72 may be composed of an inorganic insulating material such as silicon nitride (SiNx), silicon oxide (SiOx) or silicon oxynitride (SiOxNy) or an organic resin material such as an acrylic resin or a polyimide resin. Each optical adjustment layer 72 may be a single layer, or may be a laminated film including a plurality of materials. In addition, the number of stacked layers may be different depending on the type of the light emitting element 12.

[0309] The first electrode 121 may be formed using a transparent conductive material such as indium tin oxide (ITO), indium zinc oxide (IZO), or zinc oxide (ZnO).

[0310] The second electrode 123 is required to function as a semi-transmissive reflective film and may include magnesium (Mg), silver (Ag), a magnesium-silver alloy (MgAg) containing these materials as a main component, an alloy containing an alkali metal or an alkaline earth metal, or the like.

[0311] (Resonator Structure: Second Example)

[0312] Fig.17 B is a schematic cross-sectional view for explaining a second example of the resonator structure.

[0313] Furthermore, in the second example, the first electrode 121 and the second electrode 123 are formed to have a common film thickness in each light emitting element 12 .

[0314] Then, also in the second example, the reflector 71 is arranged below the first electrode 121 of the light emitting element 12, with the optical adjustment layer 72 interposed therebetween. A resonance structure that causes resonance of light generated by the OLED layer 122 is formed between the reflector 71 and the second electrode 123. Similar to the first example, the reflector 71 is formed to have a common film thickness in each light emitting element 12, and the film thickness of the optical adjustment layer 72 is different depending on the color to be displayed by the pixel.

[0315] exist Fig.17 In the first example shown in FIG. 1A , the upper surfaces of the reflectors 71 in the light emitting elements 12R, 12G, and 12B have been arranged to be aligned, and the position of the upper surface of the second electrode 123 differs depending on the type of the light emitting elements 12R, 12G, and 12B.

[0316] On the other hand, Fig.17 In the second example shown in FIG. 1B, the upper surface of the second electrode 123 is arranged to be aligned with the light-emitting elements 12R, 12G, and 12B. In order to align the upper surface of the second electrode 123, the upper surface of the reflector 71 in the light-emitting elements 12R, 12G, and 12B is arranged differently according to the type of the light-emitting elements 12R, 12G, and 12B. Therefore, the lower surface of the reflector 71 (in other words, the upper surface of the base layer (insulating layer) 73) has a stepped shape according to the type of the light-emitting element 12.

[0317] Materials constituting the reflector 71 , the optical adjustment layer 72 , the first electrode 121 , and the second electrode 123 and the like are similar to those described in the first example, and thus description thereof is omitted.

[0318] (Resonator Structure: Third Example)

[0319] Fig.18 A is a schematic cross-sectional view for explaining a third example of the resonator structure. In the following description, the reflectors 71 provided corresponding to the sub-pixels 10R, 10G, and 10B may be referred to as reflectors 71R, 71G, and 71B, respectively.

[0320] In the third example, the first electrode 121 and the second electrode 123 are formed to have a common film thickness in each light emitting element 12 .

[0321] Then, also in the third example, the reflector 71 is arranged below the first electrode 121 of the light emitting element 12, with the optical adjustment layer 72 interposed therebetween. A resonance structure that causes resonance of light generated by the OLED layer 122 is formed between the reflector 71 and the second electrode 123. Similar to the first and second examples, the film thickness of the optical adjustment layer 72 is different depending on the color to be displayed by the pixel. Then, similar to the second example, the light emitting elements 12R, 12G, and 12B are arranged so that the positions of the upper surfaces of the second electrodes 123 are aligned.

[0322] exist Fig.17 In the second example shown in b of FIG. 3B , in order to align the upper surface of the second electrode 123 , the lower surface of the reflector 71 has a stepped shape according to the type of the light emitting element 12 .

[0323] On the other hand, Fig.18 In the third example shown in FIG. 1A , the film thickness of the reflector 71 is set to be different according to the types of the light emitting elements 12R, 12G, and 12B. More specifically, the film thickness is set so that the lower surfaces of the reflectors 71R, 71G, and 71B are aligned.

[0324] Materials constituting the reflector 71 , the optical adjustment layer 72 , the first electrode 121 , and the second electrode 123 and the like are similar to those described in the first example, and thus description thereof is omitted.

[0325] (Resonator Structure: Fourth Example)

[0326] Fig.18 B is a schematic cross-sectional view for explaining a fourth example of the resonator structure. In the following description, the first electrodes 121 provided corresponding to the sub-pixels 10R, 10G, and 10B may be referred to as first electrodes 121R, 121G, and 121B, respectively.

[0327] exist Fig.17 In the first example shown in A, the first electrode 121 and the second electrode 123 of each light emitting element 12 are formed to have a common film thickness. Then, the reflector 71 is provided below the first electrode 121 of the light emitting element 12 with the optical adjustment layer 72 interposed therebetween.

[0328] On the other hand, Fig.18 In the fourth example shown in FIG. 1B , the optical adjustment layer 72 is omitted, and the film thickness of the first electrode 121 is set to be different according to the types of the light emitting elements 12R, 12G, and 12B.

[0329] The reflector 71 is formed to have a common film thickness in each light emitting element 12. The film thickness of the first electrode 121 is different according to the color to be displayed by the pixel. Because the first electrodes 121R, 121G and 121B have different film thicknesses, the optical distance that causes the optimal resonance of the wavelength of light can be set according to the color to be displayed.

[0330] Materials constituting the reflector 71 , the optical adjustment layer 72 , the first electrode 121 , and the second electrode 123 and the like are similar to those described in the first example, and thus description thereof is omitted.

[0331] (Resonator Structure: Fifth Example)

[0332] Fig.19 A is a schematic cross-sectional view for explaining a fifth example of the resonator structure.

[0333] exist Fig.17 In the first example shown in A, the first electrode 121 and the second electrode 123 are formed to have a common film thickness in each light emitting element 12. Then, the reflector 71 is provided below the first electrode 121 of the light emitting element 12 with the optical adjustment layer 72 interposed therebetween.

[0334] On the other hand, Fig.19 In the fifth example shown in FIG. 1A, the optical adjustment layer 72 has been omitted, and instead, an oxide film 74 has been formed on the surface of the reflector 71. The film thickness of the oxide film 74 is set to be different according to the type of the light emitting elements 12R, 12G, and 12B. In the following description, the oxide film 74 provided corresponding to the sub-pixels 10R, 10G, and 10B may be referred to as oxide films 74R, 74G, and 74B, respectively.

[0335] The film thickness of the oxide film 74 varies depending on the color displayed by the pixel. Since the film thicknesses of the oxide films 74R, 74G, and 74B are different, the optical distance that produces the best resonance for the wavelength of light can be set according to the color displayed.

[0336] Oxide film 74 is a film obtained by oxidizing the surface of reflector 71 and includes, for example, aluminum oxide, tantalum oxide, titanium oxide, magnesium oxide, zirconium oxide, etc. Oxide film 74 serves as an insulating film for adjusting the optical path length (optical distance) between reflector 71 and second electrode 123 .

[0337] Depending on the types of the light emitting elements 12R, 12G, and 12B, the oxide films 74 having different film thicknesses may be formed, for example, as follows.

[0338] First, an electrolyte is filled in a container, and the substrate on which the reflector 71 is formed is immersed in the electrolyte. In addition, an electrode is arranged to face the reflector 71.

[0339] Then, a positive voltage is applied to the reflector 71 with respect to the electrode, and the reflector 71 is anodized. The film thickness of the oxide film due to anodization is proportional to the voltage value of the electrode. Therefore, anodization is performed in a state where a voltage according to the type of the light emitting element 12 is applied to each of the reflectors 71R, 71G, and 71B. Thus, oxide films 74 with different film thicknesses can be formed at once.

[0340] Materials and the like constituting the reflector 71 , the first electrode 121 , and the second electrode 123 are similar to those described in the first example, and thus description thereof is omitted.

[0341] (Resonator Structure: Sixth Example)

[0342] Fig.19 B is a schematic cross-sectional view for explaining a sixth example of the resonator structure.

[0343] In the sixth example, the light emitting element 12 is configured by stacking a first electrode 121, an OLED layer 122, and a second electrode 123. However, in the sixth example, the first electrode 121 is formed to function as both an electrode and a reflector. The first electrode (also used as a reflector) 121 includes a material having an optical constant selected according to the type of the light emitting element 12R, 12G, and 12B. Since the phase shift of the first electrode (also used as a reflector) 121 changes, the optical distance that causes the optimal resonance of the wavelength of light can be set according to the color to be displayed.

[0344] The first electrode (also used as a reflector) 121 may include a single component metal such as aluminum (Al), silver (Ag), gold (Au) or copper (Cu), or an alloy containing these metals as a main component. For example, the first electrode (also used as a reflector) 121R of the light emitting element 12R may be formed to contain copper (Cu), and the first electrode (also used as a reflector) 121G of the light emitting unit 12G and the first electrode (also used as a reflector) 121B of the light emitting element 12B may be formed to contain aluminum.

[0345] The material and the like constituting the second electrode 123 are similar to those described in the first example, and thus the description thereof will be omitted.

[0346] (Resonator Structure: Seventh Example)

[0347] Fig. 20 is a schematic cross-sectional view for explaining a seventh example of the resonator structure.

[0348] In the seventh example, basically, the sixth example is applied to the light emitting elements 12R and 12G, and the first example is applied to the light emitting element 12 B. Also in this configuration, the optical distance causing the optimum resonance of the wavelength of light can be set according to the color to be displayed.

[0349] The first electrodes (also serving as reflectors) 121R and 121G for the light emitting elements 12R and 12G may be formed to contain a single metal such as aluminum (Al), silver (Ag), gold (Au), or copper (Cu) or an alloy containing these as a main component.

[0350] Materials and the like constituting the reflector 71B, the optical adjustment layer 72B, and the first electrode 121B for the light emitting element 12B are similar to those described in the first example, and thus description thereof is omitted.

[0362] The light emitting element 327 can emit near infrared rays. The light emitting element 327 is, for example, an LED element. The near infrared rays emitted from the light emitting element 327 are reflected by the heat mirror 325 and enter the eye 329.

[0363] The imaging element 328 is an imaging element for eye tracking, and can image near infrared rays reflected by the eye 329 .

[0364] As eye tracking of the head mounted display 320, for example, a pupil center corneal reflection (PCCR) method is used. In the pupil center corneal reflection method, a reflection point of light is generated on the cornea, and an image is captured by the imaging element 328. The reflection points of light on the cornea and the pupil are identified from the captured image of the eyeball. The direction of the eyeball is calculated based on the reflection points of light and other geometric features. The reflection pattern generated on the cornea by the near infrared ray from the light emitting element 327 is obtained by the imaging element 328. Advanced image processing algorithms and physiological 3D models of the eyeball can be used to estimate the position and viewpoint of the eye in space with high accuracy.

[0365] The head mounted display 320 of the specific example 2 includes any one of the display device 101 and the like as the screen 323. Therefore, this enables the generation of stray light of near infrared rays to be suppressed. Thus, image noise caused by stray light of near infrared rays can be suppressed.
