Description

Technical Field

[0001] The present invention relates to an electro-optical device and an electronic device.

Background Art

[0002] An electro-optical device having a light-emitting element such as an organic EL (electroluminescence) element is known. In this type of device, generally, for example, as disclosed in Patent Document 1, a color filter that transmits light in a predetermined wavelength range among the light from the light-emitting element is provided.

[0003] The electro-optical device described in Patent Document 1 has four sub-pixels for each of a plurality of pixels arranged in a matrix in the X direction and the Y direction orthogonal to the X direction. The four sub-pixels are composed of an R pixel and a G pixel adjacent to each other in the X direction, and two B pixels adjacent to the R pixel and the G pixel in the Y direction and adjacent to each other in the X direction.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the electro-optical device described in Patent Document 1, a plurality of rows in which color filters corresponding to R pixels and G pixels are alternately repeated in the X direction and a plurality of rows in which only color filters corresponding to B pixels are arranged in the X direction are alternately arranged in the Y direction.

[0006] Here, in the rows of color filters corresponding to R pixels and G pixels, color filters of different colors are arranged alternately, so the color filter of one of two adjacent sub-pixels affects the light distribution characteristics of the other sub-pixel. In contrast, in the row of color filters corresponding to B pixels, color filters of the same color are provided integrally, so the color filter of one of two adjacent sub-pixels does not affect the light distribution characteristics of the other sub-pixel. As a result, in the electro-optical device described in Patent Document 1, there is a problem that a difference occurs between the light distribution characteristics of B pixels and the light distribution characteristics of R pixels and G pixels.

Best Mode for Carrying Out the Invention

[0011] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Note that the dimensions and scales of each part in the drawings are appropriately different from the actual ones, and there are also parts schematically shown for easy understanding. The scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0012] 1. Electro-optical device 1A. First Embodiment 1A-1. Outline of Electro-optical Device FIG. 1 is a plan view schematically showing an electro-optical device 100 according to the first embodiment. The electro-optical device 100 is a device that displays an image using an organic EL. The electro-optical device 100 is, for example, a microdisplay suitably used for a head-mounted display or the like.

[0013] Hereinafter, the electro-optical device 100 will be described. For convenience, the X-axis, Y-axis, and Z-axis orthogonal to each other are appropriately used in the following description. Also, hereinafter, one direction along the X-axis is the X1 direction, and the direction opposite to the X1 direction is the X2 direction. Similarly, one direction along the Y-axis is the Y1 direction, and the direction opposite to the Y1 direction is the Y2 direction. One direction along the Z-axis is the Z1 direction, and the direction opposite to the Z1 direction is the Z2 direction. Here, the Y1 direction or the Y2 direction is an example of the "first direction". The X1 direction or the X2 direction is an example of the "second direction". Also, hereinafter, looking in the Z1 direction or the Z2 direction may be referred to as "plan view".

[0014] The electro-optical device 100 has a display area A10 for displaying an image and a peripheral area A20 surrounding the display area A10 in plan view. In the example shown in FIG. 1, the shape of the display area A10 in plan view is a rectangle. Note that the shape of the display area A10 in plan view is not limited to the example shown in FIG. 1, and other shapes may also be used.

[0015] The display area A10 is composed of a plurality of pixels P. Each pixel P is the minimum unit in image display. The plurality of pixels P are arranged in a matrix along the X-axis and Y-axis directions, for example. Each pixel P has a sub-pixel PB for obtaining light in the blue wavelength range, a sub-pixel PG for obtaining light in the green wavelength range, and a sub-pixel PR for obtaining light in the red wavelength range. Here, the red wavelength range is an example of the "first wavelength range", the blue wavelength range is an example of the "second wavelength range", and the green wavelength range is an example of the "third wavelength range".

[0016] Note that hereinafter, without distinguishing between the sub-pixel PB, the sub-pixel PG, and the sub-pixel PR, each of them may be referred to as a sub-pixel P0. The sub-pixel P0 is the minimum unit capable of independently controlling light emission.

[0017] As shown in FIG. 1, the electro-optical device 100 has an element substrate 200 and a light-transmissive substrate 300 having light transmissibility. The electro-optical device 100 has a so-called top emission structure. The electro-optical device 100 emits light from the light-transmissive substrate 300. Note that light transmissibility means transmissibility with respect to visible light, and preferably means that the transmittance of visible light is 50% or more.

[0018] The element substrate 200 has a data line driving circuit 101, a scanning line driving circuit 102, a control circuit 103, and a plurality of external terminals 104. The data line driving circuit 101, the scanning line driving circuit 102, the control circuit 103, and the plurality of external terminals 104 are arranged in the peripheral area A20. The data line driving circuit 101 and the scanning line driving circuit 102 are peripheral circuits for controlling the driving of a plurality of sub-pixels P0. The control circuit 103 controls the driving of the data line driving circuit 101 and the scanning line driving circuit 102. Image data is supplied to the control circuit 103 from an upper circuit (not shown). The control circuit 103 supplies various signals based on the image data to the data line driving circuit 101 and the scanning line driving circuit 102. Although not shown, an FPC (Flexible printed circuits) substrate or the like for electrical connection with an upper circuit is connected to the external terminal 104. Also, a power supply circuit (not shown) is electrically connected to the element substrate 200.

[0019] The light-transmissive substrate 300 is a cover that protects the element substrate 200 and the like. The light-transmissive substrate 300 is composed of, for example, a glass substrate or a quartz substrate. The light-transmissive substrate 300 is joined to the element substrate 200 via an adhesive (not shown). The adhesive is, for example, a transparent adhesive using a resin material such as an epoxy resin or an acrylic resin.

[0020] FIG. 2 is an equivalent circuit diagram of the sub-pixel P0 shown in FIG. 1. The element substrate 200 is provided with a plurality of scanning lines 111, a plurality of data lines 112, a plurality of power supply lines 113, and a plurality of power supply lines 114. In FIG. 2, one sub-pixel P0 and the elements corresponding thereto are typically shown.

[0021] The scanning lines 111 extend in a direction along the X-axis, while the data lines 112 extend in a direction along the Y-axis. Although not shown, the plurality of scanning lines 111 and the plurality of data lines 112 are arranged in a grid pattern. Also, although not shown, the scanning lines 111 are connected to the scanning line driving circuit 102 shown in FIG. 1, and the data lines 112 are connected to the data line driving circuit 101 shown in FIG. 1.

[0022] As shown in FIG. 2, the element substrate 200 includes, for each sub-pixel P0, a light-emitting element 120 and a pixel circuit 130 that supplies current to the light-emitting element 120. The light-emitting element 120 is composed of an OLED (organic light-emitting diode). As will be described in detail later, the light-emitting element 120 includes a pixel electrode 226, a common electrode 229, and an organic layer 228 disposed therebetween.

[0023] The pixel electrode 226 is electrically connected to the power supply line 113 via the pixel circuit 130. On the other hand, the common electrode 229 is electrically connected to the power supply line 114. Here, the high-level power supply potential Vel is supplied to the power supply line 113 from a power supply circuit (not shown). The low-level power supply potential Vct is supplied to the power supply line 114 from a power supply circuit (not shown). Therefore, the pixel electrode 226 functions as an anode, and the common electrode 229 functions as a cathode. In the light-emitting element 120, holes supplied from the pixel electrode 226 and electrons supplied from the common electrode 229 recombine in the organic layer 228, causing the organic layer 228 to generate light.

[0024] The pixel circuit 130 includes a switching transistor 131, a driving transistor 132, and a holding capacitor 133. The gate of the switching transistor 131 is electrically connected to the scanning line 111. One of the source and drain of the switching transistor 131 is electrically connected to the data line 112, and the other is electrically connected to the gate of the driving transistor 132. One of the source and drain of the driving transistor 132 is electrically connected to the power supply line 113, and the other is electrically connected to the pixel electrode 226. One of the two electrodes of the holding capacitor 133 is connected to the gate of the driving transistor 132, and the other is connected to the power supply line 113.

[0025] In the above pixel circuit 130, when the scanning line driving circuit 102 activates the scanning signal and the scanning line 111 is selected, the switching transistor 131 provided in the selected sub-pixel P0 is turned on. Then, a data signal is supplied from the data line 112 to the driving transistor 132 corresponding to the selected scanning line 111. The driving transistor 132 supplies a current corresponding to the potential of the supplied data signal, that is, the potential difference between the gate and the source, to the light-emitting element 120. As a result, the light-emitting element 120 emits light with a luminance corresponding to the magnitude of the current supplied from the driving transistor 132. Thereafter, when the scanning line driving circuit 102 releases the selection of the scanning line 111 and the switching transistor 131 is turned off, the potential of the gate of the driving transistor 132 is held by the holding capacitor 133. Therefore, the light emission of the light-emitting element 120 can be maintained even after the switching transistor 131 is turned off.

[0026] Note that the configuration of the pixel circuit 130 described above is not limited to the illustrated configuration. For example, the pixel circuit 130 may further include a transistor that controls the conduction between the pixel electrode 226 and the driving transistor 132.

[0027] 1A-2. Details of the Element Substrate FIG. 3 is a plan view showing a part of the element substrate 200 in the first embodiment. FIG. 4 is a cross-sectional view taken along line A-A in FIG. 3. FIG. 5 is a cross-sectional view taken along line B-B in FIG. 3. FIG. 6 is a cross-sectional view taken along line C-C in FIG. 3. In FIG. 3, among the elements constituting the element substrate 200, the elements in one pixel P are typically illustrated. Also, in FIG. 3, for ease of viewing, the illustration of the overcoat layer 250 described later is omitted.

[0028] As shown in FIG. 3, the element substrate 200 has a set of light-emitting elements 120R, 120G1, 120G2, and 120B for each pixel P. The light-emitting element 120R is a light-emitting element 120 provided in the sub-pixel PR. Each of the light-emitting elements 120G1 and 120G2 is a light-emitting element 120 provided in the sub-pixel PG. The light-emitting element 120B is a light-emitting element 120 provided in the sub-pixel PB.

[0029] Here, the light-emitting element 120R is an example of the "first light-emitting element", the light-emitting element 120B is an example of the "second light-emitting element", the light-emitting element 120G1 is an example of the "third light-emitting element", and the light-emitting element 120G2 is an example of the "fourth light-emitting element".

[0030] However, the light-emitting elements 120G1 and 120G2 share one pixel circuit 130 for each sub-pixel PG. Therefore, the light-emitting elements 120G1 and 120G2 may be regarded as one light-emitting element 120 for each sub-pixel PG. In this case, the light-emitting element 120G for each sub-pixel PG is an example of the "third light-emitting element". Note that individual pixel circuits 130 may be provided for the light-emitting elements 120G1 and 120G2.

[0031] In the present embodiment, the light-emitting elements 120R, 120G1, 120G2, and 120B are arranged in a matrix in the directions along the X-axis and the Y-axis. Here, with respect to the light-emitting element 120R, the light-emitting element 120G1 is arranged at a position in the X1 direction, and the light-emitting element 120B is arranged at a position in the Y2 direction. The light-emitting element 120G2 is arranged at a position in the Y2 direction with respect to the light-emitting element 120G1 and in the X1 direction with respect to the light-emitting element 120B.

[0032] The light-emitting element 120R has a light-emitting region RR that emits light LLR for the sub-pixel PR. The light-emitting element 120G1 has a light-emitting region RG1 that emits light LLG1 for the sub-pixel PG. The light-emitting element 120G2 has a light-emitting region RG2 that emits light LLG2 for the sub-pixel PG. The light-emitting element 120B has a light-emitting region RB that emits light LLB for the sub-pixel PB.

[0033] Here, the optical LLR is light in a wavelength range including the "first wavelength range", the optical LLB is light in a wavelength range including the "second wavelength range", and each of the optical LLG1 and LLG2 is light in a wavelength range including the "third wavelength range". Further, the light-emitting region RR is an example of the "first light-emitting region", the light-emitting region RB is an example of the "second light-emitting region", the light-emitting region RG1 is an example of the "third light-emitting region", and the light-emitting region RG2 is an example of the "fourth light-emitting region". Note that the light-emitting regions RG1 and RG2 may be regarded as one light-emitting region RG for each sub-pixel PG. In this case, the light-emitting regions RG1 and RG2 for each sub-pixel PG are an example of the "third light-emitting region".

[0034] In the example shown in FIG. 3, each of the light-emitting regions RR, RG1, RG2, and RB forms an octagon in plan view. The area of the light-emitting region RR is smaller than the areas of the light-emitting regions RB and RG, respectively. Also, the area of the light-emitting region RR is equal to the area of the light-emitting region RG1. Further, the area of the light-emitting region RB is equal to the area of the light-emitting region RG2. Here, the area of the light-emitting region RR is smaller than the sum of the areas of the light-emitting regions RG1 and RG2. That is, the area of the light-emitting region RR is smaller than the area of the light-emitting region RG. Here, the "area" of each of these regions refers to the area in plan view. Note that the area of the light-emitting region RR may be different from the area of the light-emitting region RG1. Also, the shape of each of the light-emitting regions RR, RG1, RG2, and RB is not limited to an octagon and may be other shapes. Further, the shapes of the light-emitting regions RR, RG1, RG2, and RB in plan view may be different from each other.

[0035] As shown in FIGS. 4 and 5, the element substrate 200 includes a substrate 210, a light-emitting element layer 220, a sealing layer 230, a color filter 240, and an overcoat layer 250. These layers are laminated in this order in the Z1 direction. Note that each layer constituting the element substrate 200 is formed by appropriately using a known film-forming method.

[0036] The substrate 210 is, for example, a silicon substrate. Although not shown, the pixel circuit 130 and various wirings connected thereto are formed on the substrate 210. Note that the substrate 210 is not limited to a silicon substrate, and may be, for example, a glass substrate, a resin substrate, or a ceramic substrate. In this embodiment, since the electro-optical device 100 is a top emission type, the substrate 210 does not necessarily have to be light transmissive. Each of the transistors included in the pixel circuit 130 may be any of a MOS transistor, a thin film transistor, or a field effect transistor. When the transistor included in the pixel circuit 130 is a MOS transistor having an active layer, the active layer may be formed of a silicon substrate. In addition, examples of materials for each part and various wirings constituting the pixel circuit 130 include conductive materials such as polysilicon, metal, metal silicide, and metal compound.

[0037] The light emitting element layer 220 is a layer in which the light emitting elements 120R, 120G1, 120G2, and 120B are provided. Specifically, the light emitting element layer 220 includes an insulating layer 221, a reflective layer 222, a reflective enhancing layer 223, an insulating layer 224, a distance adjusting layer 225, a plurality of pixel electrodes 226R, 226G1, 226G2, and 226B, an element isolation layer 227, an organic layer 228, and a common electrode 229. These layers are laminated in this order in the Z1 direction.

[0038] The insulating layer 221 is an interlayer insulating film disposed between the substrate 210 and the reflective layer 222. The insulating layer 221 is formed of an insulating material such as silicon oxide (SiO 2 ) or the like.

[0039] The reflective layer 222 is a layer having light reflectivity that reflects the light generated in the organic layer 228 in the Z1 direction. Although not shown, the reflective layer 222 is divided into a plurality of portions that are arranged in a matrix corresponding to a plurality of sub-pixels P0 in a plan view. Examples of the constituent material of the reflective layer 222 include metals such as Al (aluminum), Ag (silver), Cu (copper), Ti (titanium), or alloys of any of these metals. For example, the reflective layer 222 is composed of a laminate of a film made of Ti and a film made of an alloy containing Al and Cu. In the examples shown in FIGS. 4 and 5, the reflective layer 222 also functions as a wiring. Although not shown, the wiring is electrically connected to, for example, the aforementioned pixel circuit 130. Note that the reflective layer 222 does not necessarily have to function as the wiring. In this case, wiring is provided separately from the reflective layer 222. Further, the light reflectivity means reflectivity with respect to visible light, and preferably means that the reflectivity of visible light is 50% or more.

[0040] The anti-reflection layer 223 is a layer having light transmissivity and insulating properties for enhancing the light reflectivity of the reflective layer 222. The anti-reflection layer 223 is arranged in a range covering the entire area of the reflective layer 222 in a plan view. The anti-reflection layer 223 is composed of, for example, a silicon oxide film.

[0041] The insulating layer 224 has a first insulating layer 224a and a second insulating layer 224b. The first insulating layer 224a fills the spaces between the divided portions of the reflective layer 222 and the anti-reflection layer 223 and is arranged over the entire area on the anti-reflection layer 223. The second insulating layer 224b is arranged over the entire area on the first insulating layer 224a. Each of the first insulating layer 224a and the second insulating layer 224b is composed of, for example, a silicon nitride (SiN) film.

[0042] The distance adjustment layer 225 is a layer having light transmissivity and insulating properties for adjusting the distance between the reflective layer 222 and the common electrode 229 for each sub-pixel P0. The distance adjustment layer 225 has a first distance adjustment layer 225a and a second distance adjustment layer 225b. Each of the first distance adjustment layer 225a and the second distance adjustment layer 225b is, for example,

[0043] The first distance adjustment layer 225a is disposed on the sub-pixel PR among the sub-pixels PR, PG, and PB, and is not disposed on the sub-pixels PG and PB. The second distance adjustment layer 225b is disposed on the sub-pixels PR and PG among the sub-pixels PR, PG, and PB, and is not disposed on the sub-pixel PB. Therefore, the first distance adjustment layer 225a and the second distance adjustment layer 225b are disposed on the sub-pixel PR. The second distance adjustment layer 225b among the first distance adjustment layer 225a and the second distance adjustment layer 225b is disposed on the sub-pixel PG. Neither the first distance adjustment layer 225a nor the second distance adjustment layer 225b is disposed on the sub-pixel PB.

[0044] Each of the pixel electrodes 226R, 226G1, 226G2, and 226B is a layer provided for each sub-pixel P0 and having conductivity and light transmissivity. However, the pixel electrodes 226G1 and 226G2 are shared by the sub-pixel PG. Examples of the constituent materials of each of the pixel electrodes 226R, 226G1, 226G2, and 226B include transparent conductive materials such as ITO (Indium Tin Oxide) and IZO (Indium Zinc Oxide).

[0045] The pixel electrode 226R is the pixel electrode 226 provided for the sub-pixel PR. The pixel electrodes 226G1 and 226G2 are the pixel electrodes 226 provided for the sub-pixel PG. The pixel electrode 226B is the pixel electrode 226 provided for the sub-pixel PB. Note that the pixel electrode 226R is an example of the "first pixel electrode". The pixel electrode 226B is an example of the "second pixel electrode". The pixel electrode 226G1 is an example of the "third pixel electrode". The pixel electrode 226G 2 is an example of the "fourth pixel electrode".

[0046] The element isolation layer 227 is an insulating layer that covers the outer edges of the pixel electrodes 226R, 226G1, 226G2, and 226B. The element isolation layer 227 is made of an insulating material such as silicon oxide, for example. The element isolation layer 227 is provided with a plurality of openings for bringing predetermined regions of the pixel electrodes 226R, 226G1, 226G2, and 226B into contact with the organic layer 228. The light-emitting regions RR, RG1, RG2, and RB are defined by the plurality of openings.

[0047] Here, the region where the pixel electrode 226R contacts the organic layer 228 is equal to the light-emitting region RR in plan view. Similarly, the region where the pixel electrode 226G1 contacts the organic layer 228 is equal to the light-emitting region RG1 in plan view. The region where the pixel electrode 226G2 contacts the organic layer 228 is equal to the light-emitting region RG2 in plan view. The region where the pixel electrode 226B contacts the organic layer 228 is equal to the light-emitting region RB in plan view.

[0048] The organic layer 228 is a layer composed mainly of an organic compound. Specifically, the organic layer 228 includes a light-emitting layer that emits light when energized. In the present embodiment, the light-emitting layer has, for example, a light-emitting layer that provides a red emission color, a light-emitting layer that provides a green emission color, and a light-emitting layer that provides a blue emission color, and these are laminated as appropriate. For this reason, light emission of white or a color close thereto is realized in the organic layer 228. Note that known configurations and materials can be applied to the organic layer 228. Although not shown, the organic layer 228 may appropriately include a hole injection layer, a hole transport layer, an electron transport layer, an electron injection layer, etc., in addition to the light-emitting layer. Further, the organic layer 228 may include a layer made of an inorganic material such as metal as necessary.

[0049] The common electrode 229 is provided in common to the sub-pixels PR, PG, and PB, and is a layer having light reflectivity, light transmissivity, and conductivity. Examples of the constituent material of the common electrode 229 include an alloy such as MgAg containing Ag.

[0050] In the above light-emitting element layer 220, the light-emitting element 120R includes an insulating layer 221, a reflective layer 222, an anti-reflection layer 223, an insulating layer 224, a first distance adjustment layer 225a, a second distance adjustment layer 225b, a pixel electrode 226R, an element isolation layer 227, an organic layer 228, and a common electrode 229. The light-emitting element 120G1 has the same layer structure as the light-emitting element 120R except that the first distance adjustment layer 225a is omitted and a pixel electrode 226G1 is provided instead of the pixel electrode 226R. The light-emitting element 120G2 has the same layer structure as the light-emitting element 120R except that the first distance adjustment layer 225a is omitted and a pixel electrode 226G2 is provided instead of the pixel electrode 226R. The light-emitting element 120B has the same layer structure as the light-emitting element 120R except that the first distance adjustment layer 225a and the second distance adjustment layer 225b are omitted and a pixel electrode 226B is provided instead of the pixel electrode 226R.

[0051] Here, the distance between the reflective layer 222 and the common electrode 229 is different for each sub-pixel P0. Specifically, the distance in the sub-pixel PR is set corresponding to the red wavelength range. The distance in the sub-pixel PG is set corresponding to the green wavelength range. The distance in the sub-pixel PB is set corresponding to the blue wavelength range.

[0052] Therefore, in the sub-pixel PR, an optical resonance structure that resonates light of the red wavelength between the reflective layer 222 and the common electrode 229 is realized. In the sub-pixel PG, an optical resonance structure that resonates light of the green wavelength between the reflective layer 222 and the common electrode 229 is realized. In the sub-pixel PB, an optical resonance structure that resonates light of the blue wavelength between the reflective layer 222 and the common electrode 229 is realized.

[0053] The resonance wavelength in the above-described optical resonance structure is determined by the distance between the reflective layer 222 and the common electrode 229. When the distance is L0 and the resonance wavelength is λ0, the following relational expression [1] holds. Note that Φ (radian) in the relational expression [1] represents the total phase shift that occurs during transmission and reflection between the reflective layer 222 and the common electrode 229. {(2×L0) / λ0 + Φ} / (2π) = m0 (m0 is an integer) ····· [1]

[0054] The distance L0 is set such that the peak wavelength of the light in the wavelength range to be extracted becomes the wavelength λ0. With this setting, the light in the predetermined wavelength range to be extracted is enhanced, and the intensity of the light can be increased and the spectrum can be narrowed down.

[0055] As described above, in the present embodiment, the distance L0 is adjusted by varying the thickness of the distance adjustment layer 225 for each sub-pixel P0. Note that the method for adjusting the distance L0 is not limited to the method of adjusting by the thickness of the distance adjustment layer 225. For example, the distance L0 may be adjusted by varying the thickness of the pixel electrode 226 for each of the sub-pixels PB, PG, and PR.

[0056] The sealing layer 230 is a layer having gas barrier properties and light transmissivity for sealing the light-emitting element layer 220 to protect it from external moisture, oxygen, etc. Specifically, the sealing layer 230 includes a first layer 231, a second layer 232, and a third layer 233. These layers are laminated in the Z1 direction in this order. Each of the first layer 231 and the third layer 233 is a layer having light transmissivity for enhancing gas barrier properties. Each of the first layer 231 and the third layer 233 is formed of, for example, a silicon oxynitride (SiON) film. The second layer 232 is a layer having light transmissivity for providing a flat surface to the third layer 233. The second layer 232 is formed of, for example, a resin material such as an epoxy resin.

[0057] The color filter 240 is a layer that selectively transmits light in a predetermined wavelength range among the light from the light-emitting element 120. By using the color filter 240, the color purity of the light emitted from each sub-pixel P0 in the desired color can be increased as compared with the case where the color filter 240 is not used.

[0058] Specifically, the color filter 240 includes colored layers 241R, 241G, and 241B, a light-shielding portion 242, and an adhesion layer 243. Here, the colored layer 241R is an example of the "first colored layer", the colored layer 241B is an example of the "second colored layer", and the colored layer 241G is an example of the "third colored layer".

[0059] The color layer 241R is provided in the sub-pixel PR and is a filter that selectively transmits light in the red wavelength range among the light from the light-emitting element 120R. The color layer 241G is provided in the sub-pixel PG and is a filter that selectively transmits light in the green wavelength range among the light from the light-emitting elements 120G1 and 120G2. The color layer 241B is provided in the sub-pixel PB and is a filter that selectively transmits light in the blue wavelength range among the light from the light-emitting element 120B. The color layers 241R, 241G, and 241B are composed of a resin material such as an acrylic photosensitive resin material containing a colorant such as a pigment or dye of the corresponding color.

[0060] As shown in FIG. 3, the color layers 241R, 241G, and 241B are provided so as to overlap the light-emitting regions of the light-emitting elements 120 that emit light in the corresponding wavelength ranges in a plan view. Therefore, the color layer 241R and the color layer 241B are arranged side by side in the direction along the Y axis. The color layer 241R and the color layer 241G are arranged side by side in the direction along the X axis. The color layer 241B and the color layer 241G are arranged side by side in the direction along the X axis. Here, the color layer 241R forms a rectangle having a long side along the X axis in a plan view. The color layer 241B forms a rectangle having a long side along the Y axis in a plan view. The color layer 241G has a shape extending in the direction along the Y axis in a plan view. More specifically, the color layer 241G has color layers 241G1 and 241G2 having different lengths along the X axis, and these are arranged side by side in the direction along the Y axis. Here, the color layer 241G1 is located in the X1 direction with respect to the color layer 241R. The color layer 241G2 is located in the X1 direction with respect to the color layer 241B.

[0061] In the present embodiment, the thicknesses of the color layers 241R and 241B are equal to each other. Also, the thickness of the color layer 241G is thinner than the thickness of the color layer 241R or 241B.

[0062] Note that the shapes, sizes, etc. of the colored layers 241R, 241G, and 241B are not limited to the examples shown in FIG. 3. For example, the planar shapes or sizes of the colored layers 241R and 241B may be equal to each other. Also, the planar shape of the colored layer 241G may be a simple rectangle. Further, the thicknesses of the colored layers 241R, 241G, and 241B are not limited to the examples shown in FIGS. 4 and 5 and are arbitrary. For example, as shown in FIGS. 15 or 19 described later, the thicknesses of the colored layers 241R and 241G may be different from each other.

[0063] The light-shielding portion 242 is a light-shielding layer provided in an island shape so as to divide the colored layer 241G into a plurality of portions arranged in a direction along the Y-axis in a plan view. The light-shielding portion 242 is made of a resin material such as an acrylic photosensitive resin material containing a coloring material such as a pigment or a dye. The coloring material may be any color as long as the color of the light-shielding portion 242 is different from the color of the colored layer 241G. However, from the viewpoint of enhancing the light-shielding property of the light from the light-emitting element 120G, it is preferable that the coloring material of the light-shielding portion 242 is a coloring material that is black or a dark color close to black. Examples of the coloring material that makes the light-shielding portion 242 black or a dark color close to black include a black coloring material such as carbon black, and a coloring material obtained by mixing a plurality of coloring materials such as red, blue, and green.

[0064] The light-shielding portion 242 may be made of a material different from the above-described colored layers 241R, 241G, and 241B, but from the viewpoint of cost reduction, etc., it may be made of the same material as the colored layers 241R, 241G, and 241B. In this case, the light-shielding portion 242 may be made of a mixed material of the constituent materials of the colored layers 241R, 241G, and 241B, or may be constituted by the lamination of the colored layer 241R, the colored layer 241B, and the colored layer 241G. When the light-shielding portion 242 is constituted by the lamination, for example, it is formed together with these layers by using the formation process of the colored layers 241R, 241G, and 241B. Note that in the present embodiment, as shown in FIG. 5, the thickness of the light-shielding portion 242 is equal to the thickness of the colored layer 241R or 241B, but it is not limited thereto. For example, as shown in FIGS. 15 or 19 described later, the thickness of the light-shielding portion 242 may be different from the thickness of the colored layer 241R or 241B.

[0065] In this embodiment, the light-shielding portion 242 includes a plurality of first light-shielding portions 242a and a plurality of second light-shielding portions 242b.

[0066] As shown in FIG. 3, in a plan view, the first light-shielding portion 242a overlaps with the region between the light-emitting regions RG1 and RG2 adjacent to each other within the same pixel P, and with the contact portions 226a (to be described later) of the light-emitting elements 120B and 120G2, respectively. Here, in a plan view, the region divides the colored layer 241G into two portions adjacent to each other in the direction along the Y axis. In the example shown in FIG. 3, the two portions are the aforementioned colored layers 241G1 and 241G2.

[0067] Here, the contact portion 226a will be described with reference to FIG. 6. As shown in FIG. 6, a relay electrode 260 is disposed between the first insulating layer 224a and the second insulating layer 224b of the insulating layer 224, and the pixel electrode 226 has a contact portion 226a that penetrates the distance adjustment layer 225 and is connected to the relay electrode 260. The relay electrode 260 is an electrode for electrically connecting the pixel electrode 226 to the pixel circuit 130, and is electrically connected to the reflective layer 222. The relay electrode 260 is provided for each light-emitting element 120, and is disposed at a position that does not overlap with the light-emitting regions RR, RG1, RG2, and RB in a plan view. Examples of the constituent material of the relay electrode 260 include conductive materials such as tungsten (W), titanium (Ti), and titanium nitride (TiN).

[0068] In the example shown in FIG. 6, an insulating layer 261 is disposed between the relay electrode 260 and the first insulating layer 224a, and the relay electrode 260 penetrates the insulating layer 261 and the first insulating layer 224a and is connected to the reflective layer 222. The insulating layer 261 is formed of, for example, a silicon oxide film. In FIG. 6, the pixel electrode 226 and the relay electrode 260 of the light-emitting element 120G1 are typically illustrated, but the pixel electrodes 226 and the relay electrodes 260 of the light-emitting elements 120R, 120G2, and 120B are configured in the same manner as the pixel electrode 226 and the relay electrode 260 of the light-emitting element 120G1.

[0069] Here, the relay electrode 260 corresponding to the light-emitting element 120R is an example of the "first relay electrode". The relay electrode 260 corresponding to the light-emitting element 120B is an example of the "second relay electrode". The relay electrode 260 corresponding to the light-emitting element 120G1 is an example of the "third relay electrode". The relay electrode 260 corresponding to the light-emitting element 120G2 is an example of the "fourth relay electrode". The contact portion 226a provided on the pixel electrode 226 of the light-emitting element 120R is an example of the "first contact portion". The contact portion 226a provided on the pixel electrode 226 of the light-emitting element 120B is an example of the "second contact portion". The contact portion 226a provided on the pixel electrode 226 of the light-emitting element 120G1 is an example of the "third contact portion". The contact portion 226a provided on the pixel electrode 226 of the light-emitting element 120G2 is an example of the "fourth contact portion".

[0070] In the configuration in which the relay electrode 260 is provided as described above, the thickness of the organic layer 228 tends to be reduced in the vicinity of the contact portion 226a. Therefore, when the light-emitting element 120 is driven at a low current, each light-emitting region tends to emit light preferentially in the portion near the contact portion 226a compared to the central portion. Such light emission in the vicinity of the contact portion 226a resonates at a frequency different from the intended resonance frequency in the above-described optical resonance structure, which causes color deviation. Therefore, it is desirable to block such light emission with the light-blocking portion 242.

[0071] In the present embodiment, as shown in FIG. 3, the width W1 of the first light-blocking portion 242a in the direction along the Y axis is constant over the entire region in the direction along the X axis. Here, the width W1 is larger than the overlapping width W0 between the coloring layer 241R and the coloring layer 241B, and smaller than the distance L1 between the light-emitting region RG1 and the light-emitting region RG2.

[0072] In addition, in the present embodiment, as shown in FIG. 5, when viewed in a cross-section orthogonal to the Y-axis, the first light-shielding portion 242a has a trapezoidal shape such that its width decreases in the Z2 direction. Therefore, while preferably shielding the light emission near the contact portion 226a described above with the first light-shielding portion 242a, the viewing angle of the sub-pixel PG can be increased. The first light-shielding portion 242a having such a cross-sectional shape is formed, for example, by using a negative-type photosensitive resin material as a constituent material. Note that the cross-sectional shape of the first light-shielding portion 242a is not limited to the example shown in FIG. 5, and may be, for example, rectangular, or may be trapezoidal such that its width decreases in the Z1 direction as shown in FIGS. 18 to 21 described later.

[0073] On the other hand, the second light-shielding portion 242b is configured in the same manner as the first light-shielding portion 242a except for the difference in arrangement. Here, the second light-shielding portion 242b overlaps, in plan view, the region between the light-emitting regions RG1 and RG2 adjacent to each other between different pixels P and the contact portions 226a of the light-emitting elements 120R and 120G1, respectively.

[0074] In the example shown in FIG. 3, the planar shapes and sizes of the first light-shielding portion 242a and the second light-shielding portion 242b are the same as each other. Note that the planar shapes and sizes of the first light-shielding portion 242a and the second light-shielding portion 242b may be different from each other.

[0075] The above-described color layers 241R, 241G, 241B and the light-shielding portion 242 are joined to the above-described sealing layer 230 via an adhesion layer 243. The adhesion layer 243 is a light-transmissive layer for enhancing the adhesion between the color filter 240 and the sealing layer 230. The adhesion layer 243 is formed of, for example, a resin material such as an epoxy resin. Note that the thickness of the adhesion layer 243 is not particularly limited and is arbitrary.

[0076] An overcoat layer 250 is partially disposed on the color filter 240 described above. The overcoat layer 250 is provided so as to overlap the color layers 241R and 241G1 so as not to overlap the color layers 241B and 241G2 in a plan view, and is a light-transmissive layer having a plurality of strip shapes extending in a direction along the X-axis. However, the overcoat layer 250 overlaps the boundary between the color layers 241B and 241G2 and the color layers 241R and 241G1 or the vicinity thereof in a plan view. The overcoat layer 250 is substantially colorless and transparent and is made of a resin material such as an acrylic photosensitive resin material containing no coloring material, for example.

[0077] By providing such an overcoat layer 250, a plurality of grooves formed by the overcoat layer 250 extend in a direction along the X-axis on the surface of the color filter 240 facing the Z1 direction. When the element substrate 200 and the translucent substrate 300 are joined with an adhesive, the plurality of grooves have an effect of smoothly spreading the adhesive in a direction along the X-axis. By this effect, the mixing of air bubbles into the layer due to the adhesive can be reduced, and the adhesion of these substrates can be suitably performed.

[0078] Note that the overcoat layer 250 may be provided so as to overlap the color layers 241B and 241G2 so as not to overlap the color layers 241R and 241G1 in a plan view. Further, the overcoat layer 250 is not limited to an aspect extending in a direction along the Y-axis, and may be in an aspect extending in a direction along the X-axis. In this case, the overcoat layer 250 is provided so as to overlap the color layers 241G1 and 241G2 so as not to overlap the color layers 241R and 241B, for example, or is provided so as to overlap the color layers 241R and 241B so as not to overlap the color layers 241G1 and 241G2.

[0079] 1A-3. Function of Light-Shielding Portion 242 FIG. 7 is a graph showing the relationship between the tristimulus values of light from pixel P and the viewing angle when the light-shielding portion 242 is omitted. FIG. 8 is a graph showing the relationship between the tristimulus values of light from pixel P and the viewing angle when the light-shielding portion 242 is provided. The horizontal axis in FIGS. 7 and 8 indicates the viewing angle, which is the angle formed between the normal direction of the display surface of the electro-optical device 100 and the observation direction when the viewing point is changed around the X axis. The vertical axis in FIGS. 7 and 8 indicates the values normalized such that the value when the angle is 0 Deg. is 1 for each of the X value, Y value, and Z value of the tristimulus values. In FIGS. 7 and 8, the X value is indicated by a broken line, the Y value is indicated by a solid line, and the Z value is indicated by a one-dot chain line.

[0080] As shown in FIG. 7, when the light-shielding portion 242 is omitted, as the viewing angle increases, the difference between the Y value and the X value or the Z value, particularly the difference between the Y value and the Z value, increases. Therefore, when the light-shielding portion 242 is omitted, the color shift with respect to the change in the viewing angle becomes large. This is because one of the adjacent color layers 241R and 241B affects the light distribution characteristics of the light from the light-emitting region corresponding to the other, while one of the adjacent color layers 241G1 and 241G2 does not affect the light distribution characteristics of the light from the light-emitting region corresponding to the other. Such a difference in the light distribution characteristics between the sub-pixels PR and PB and the sub-pixel PG becomes more prominent as the ratio of the thickness t of the sealing layer 230 to the distance between the light-emitting regions increases.

[0081] On the other hand, as shown in FIG. 8, when the light-shielding portion 242 is provided, even when the viewing angle increases, the difference between the Y value and the X value or the Z value can be made smaller than when the light-shielding portion 242 is omitted. In the example shown in FIG. 8, even when the viewing angle increases, the difference between the Y value and the Z value hardly changes. This is because when the viewing angle is increased, the light-shielding portion 242 shields the light from the light-emitting region RG1 or RG2, similar to the case where one of the color layers 241R and 241B shields the light from the light-emitting region corresponding to the other. Therefore, when the light-shielding portion 242 is provided, the color shift with respect to the change in the viewing angle can be reduced.

[0082] FIG. 9 is a graph showing the relationship between the color difference of light from pixel P and the viewing angle. The horizontal axis in FIG. 9 represents the viewing angle, similar to the horizontal axes in FIGS. 7 and 8 described above. The vertical axis in FIG. 9 represents the color difference from the display color in the reference viewing direction when the electro-optical device 100 emits white light. In FIG. 9, the case where the light-shielding portion 242 is omitted is indicated by a dashed-dotted line, and the case where the light-shielding portion 242 is provided is indicated by a solid line.

[0083] As shown in FIG. 9, when the light-shielding portion 242 is provided, even when the viewing angle increases, the color difference can be made smaller than in the case where the light-shielding portion 242 is omitted. This is because when the viewing angle is increased, the light-shielding portion 242 shields the light from the light-emitting region RG1 or RG2, similar to the case where one of the coloring layers 241R and 241B shields the light from the corresponding light-emitting region of the other. Therefore, when the light-shielding portion 242 is provided, the viewing angle characteristics can be improved.

[0084] FIG. 10 is a chromaticity diagram showing the color gamut of light from pixel P in the CIE color system. In FIG. 10, the color gamut of the CIE color system is indicated by a solid line, the color gamut defined by the NTSC (National Television System Committee) standard is indicated by a dashed line, the color gamut in the case where the light-shielding portion 242 is omitted is indicated by a two-dot chain line, and the color gamut in the case where the light-shielding portion 242 is provided is indicated by a dashed-dotted line.

[0085] As shown in FIG. 10, when the light-shielding portion 242 is provided, even when the viewing angle increases, the color gamut can be made wider than in the case where the light-shielding portion 242 is omitted. This is because the light-shielding portion 242 shields the unintended light emission near the contact portion 226a.

[0086] 1A-4. Summary of the First Embodiment As described above, the electro-optical device 100 includes a light-emitting element 120R which is an example of the "first light-emitting element", a light-emitting element 120B which is an example of the "second light-emitting element", a light-emitting element 120G1 which is an example of the "third light-emitting element", a light-emitting element 120G2 which is an example of the "fourth light-emitting element", a coloring layer 241R which is an example of the "first coloring layer", a coloring layer 241B which is an example of the "second coloring layer", a coloring layer 241G which is an example of the "third coloring layer", and a light-shielding portion 242.

[0087] Here, the light-emitting element 120R has a light-emitting region RR which is an example of the "first light-emitting region". The light-emitting region RR emits light LLR in the first wavelength range. The light-emitting element 120B has a light-emitting region RB which is an example of the "second light-emitting region". The light-emitting region RB is arranged at a position adjacent to the light-emitting region RR in the Y2 direction which is an example of the "first direction", and emits light LLB in a second wavelength range different from the first wavelength range. The light-emitting element 120G1 has a light-emitting region RG1 which is an example of the "third light-emitting region". The light-emitting region RG1 is arranged at a position adjacent to the light-emitting region RR in the X1 direction which is an example of the "second direction intersecting the first direction", and emits light LLG in a third wavelength range different from each of the first wavelength range and the second wavelength range. The light-emitting element 120G2 has a light-emitting region RG2 which is an example of the "fourth light-emitting region". The light-emitting region RG2 is arranged at a position adjacent to the light-emitting region RB in the X1 direction, and emits light LLG in the third wavelength range.

[0088] The coloring layer 241R is provided so as to overlap the light-emitting region RR in plan view, and transmits the light LLR in the first wavelength range. The coloring layer 241B is provided so as to overlap the light-emitting region RB in plan view, and transmits the light LLB in the second wavelength range. The coloring layer 241G is provided so as to overlap the light-emitting region RG1 and the light-emitting region RG2 in plan view, and transmits the light LLG in the third wavelength range.

[0089] Furthermore, the light-shielding portion 242 includes a first light-shielding portion 242a. The first light-shielding portion 242a is provided in an island shape so as to overlap with the region between the light-emitting region RG1 and the light-emitting region RG2 in a plan view, and shields at least the light LLG in the third wavelength range. Here, the first light-shielding portion 242a is provided in an island shape so as to divide the colored layer 241G into two portions arranged in the Y2 direction in a plan view. Note that the aggregate of the light-emitting region RG1 and the light-emitting region RG2 may be regarded as one light-emitting region RG, and the aggregate of the light-emitting elements 120G1 and 120G2 may be regarded as one light-emitting element 120G. In this case, the light-emitting element 120G is an example of the "third light-emitting element", and the light-emitting region RG is an example of the "third light-emitting region". Here, the first light-shielding portion 242a is provided in an island shape so as to divide the light-emitting region RG into two portions arranged in the Y2 direction in a plan view.

[0090] In the above-described electro-optical device 100, since the first light-shielding portion 242a overlaps with the region between the light-emitting region RG1 and the light-emitting region RG2 in a plan view, it is possible to reduce the difference in the light distribution characteristics of the light emitted from the light-emitting region RG1 and the light-emitting region RG2 and the light distribution characteristics of the light emitted from the light-emitting region RR and the light-emitting region RB.

[0091] Also, as described above, the electro-optical device 100 includes a relay electrode 260 included in the light-emitting element 120R as the "first relay electrode", a relay electrode 260 included in the light-emitting element 120B as the "second relay electrode", a relay electrode 260 included in the light-emitting element 120G1 as the "third relay electrode", a relay electrode 260 included in the light-emitting element 120G2 as the "fourth relay electrode", and an insulating layer 261.

[0092] Here, the light-emitting element 120R has a pixel electrode 226R which is an example of a "first pixel electrode", and a relay electrode 260 as a "first relay electrode" is electrically connected to the pixel electrode 226R. The light-emitting element 120B has a pixel electrode 226B which is an example of a "second pixel electrode", and a relay electrode 260 as a "second relay electrode" is electrically connected to the pixel electrode 226B. The light-emitting element 120G1 has a pixel electrode 226G1 which is an example of a "third pixel electrode", and a relay electrode 260 as a "third relay electrode" is electrically connected to the pixel electrode 226G1. The light-emitting element 120G2 has a pixel electrode 226G2 which is an example of a "fourth pixel electrode", and a relay electrode 260 as a "fourth relay electrode" is electrically connected to the pixel electrode 226G2. The insulating layer 261 is provided between the pixel electrode 226R and the relay electrode 260 as the first relay electrode, between the pixel electrode 226B and the relay electrode 260 as the second relay electrode, between the pixel electrode 226G1 and the relay electrode 260 as the third relay electrode, and between the pixel electrode 226G2 and the relay electrode 260 as the fourth relay electrode.

[0093] Further, the pixel electrode 226R has a contact portion 226a as a first contact portion that penetrates the insulating layer 261 and is electrically connected to the relay electrode 260 as the first relay electrode. The pixel electrode 226B has a contact portion 226a as a second contact portion that penetrates the insulating layer 261 and is electrically connected to the relay electrode 260 as the second relay electrode. The pixel electrode 226G1 has a contact portion 226a as a third contact portion that penetrates the insulating layer 261 and is electrically connected to the relay electrode 260 as the third relay electrode. The pixel electrode 226G2 has a contact portion 226a as a fourth contact portion that penetrates the insulating layer 261 and is electrically connected to the relay electrode 260 as the fourth relay electrode.

[0094] Furthermore, the first light-shielding portion 242a overlaps, in plan view, the contact portion 226a serving as the first contact portion or the second contact portion and the contact portion 226a serving as the third contact portion or the fourth contact portion. For this reason, light emission in the vicinity of each contact portion 226a of the light-emitting element 120B and the light-emitting element 120G2 can be shielded by the first light-shielding portion 242a. As a result, a decrease in the color gamut due to the light emission can be suppressed.

[0095] Depending on the arrangement of the contact portions 226a, the first light-shielding portion 242a may overlap, in plan view, each of the contact portion 226a of the light-emitting element 120R and the contact portion 226a of the light-emitting element 120G1. In this case, light emission in the vicinity of each contact portion 226a of the light-emitting element 120R and the light-emitting element 120G1 can be shielded by the first light-shielding portion 242a.

[0096] Also, as described above, the light-shielding portion 242 overlaps, in plan view, each contact portion 226a of the light-emitting element 120R, the light-emitting element 120B, the light-emitting element 120G1, and the light-emitting element 120G2. For this reason, light emission in the vicinity of each contact portion 226a of the light-emitting element 120R, the light-emitting element 120B, the light-emitting element 120G1, and the light-emitting element 120G2 can be shielded by the light-shielding portion 242. As a result, a decrease in the color gamut due to the light emission can be preferably suppressed.

[0097] Specifically, as described above, the light-shielding portion 242 further includes a second light-shielding portion 242b that overlaps, in plan view, each contact portion 226a of the light-emitting element 120R and the light-emitting element 120G1.

[0098] Here, the first light-shielding portion 242a has a first portion 242a1, a second portion 242a2, and a third portion 242a3. The first portion 242a1 overlaps with the contact portion 226a of the light-emitting element 120B in plan view. Therefore, the light emission in the vicinity of the contact portion 226a of the light-emitting element 120B can be shielded by the first portion 242a1 of the first light-shielding portion 242a. The second portion 242a2 overlaps with the contact portion 226a of the light-emitting element 120G2 in plan view. Therefore, the light emission in the vicinity of the contact portion 226a of the light-emitting element 120G2 can be shielded by the second portion 242a2 of the first light-shielding portion 242a. The third portion 242a3 is provided between the first portion 242a1 and the second portion 242a2 in plan view and is connected to each of the first portion 242a1 and the second portion 242a2. Therefore, the colored layer 241G within the same pixel can be divided into two portions arranged in the Y2 direction by the third portion 242a3 of the first light-shielding portion 242a in plan view.

[0099] The second light-shielding portion 242b has a fourth portion 242b1, a fifth portion 242b2, and a sixth portion 242b3. The fourth portion 242b1 overlaps with the contact portion 226a of the light-emitting element 120R in plan view. Therefore, the light emission in the vicinity of the contact portion 226a of the light-emitting element 120R can be shielded by the fourth portion 242b1 of the second light-shielding portion 242b. The fifth portion 242b2 overlaps with the contact portion 226a of the light-emitting element 120G1 in plan view. Therefore, the light emission in the vicinity of the contact portion 226a of the light-emitting element 120G1 can be shielded by the fifth portion 242b2 of the second light-shielding portion 242b. The sixth portion 242b3 is provided between the fourth portion 242b1 and the fifth portion 242b2 in plan view and is connected to each of the fourth portion 242b1 and the fifth portion 242b2. Therefore, the colored layer 241G between different pixels can be divided into two portions arranged in the Y2 direction by the sixth portion 242b3 of the second light-shielding portion 242b in plan view.

[0100] Such a light-shielding portion 242 may be formed by laminating the color layers 241R, 241B, and 241G as described above. In this case, a black light-shielding portion 242 can be formed without separately preparing a material different from the materials constituting the color layers 241R, 241B, and 241G. Also, in this case, the light-shielding portion 242 can be formed without performing a process separate from the formation of these color layers.

[0101] Also, as described above, the electro-optical device 100 further includes a sealing layer 230 and an adhesion layer 243. The sealing layer 230 is disposed between the light-emitting elements 120R, 120B, 120G1, and 120G2 and the light-shielding portion 242. The adhesion layer 243 is disposed in contact with the light-shielding portion 242 between the sealing layer 230 and the light-shielding portion 242 and contains a resin. Therefore, the bonding strength between the light-shielding portion 242 and the sealing layer 230 can be increased.

[0102] 1B. Second Embodiment The second embodiment will be described. In the following examples, for elements whose functions are the same as those in the first embodiment, the reference numerals used in the description of the first embodiment are reused, and the detailed description of each is appropriately omitted.

[0103] FIG. 11 is a plan view showing a part of the element substrate 200A in the second embodiment. The element substrate 200A is the same as the element substrate 200 of the first embodiment described above, except that it has a light-shielding portion 242A instead of the light-shielding portion 242. The light-shielding portion 242A is the same as the light-shielding portion 242, except that its planar shape is different. In FIG. 11, among the elements constituting the element substrate 200A, the elements in one pixel P are typically illustrated. Also, in FIG. 11, for ease of viewing, the illustration of an overcoat layer 250 described later is omitted.

[0104] As shown in FIG. 11, the light-shielding portion 242A has a plurality of first light-shielding portions 242c and a plurality of second light-shielding portions 242d.

[0105] The first light-shielding portion 242c has a first portion 242c1, a second portion 242c2, and a third portion 242c3. The first portion 242c1 overlaps with the contact portion 226a of the light-emitting element 120B in plan view. The second portion 242c2 overlaps with the contact portion 226a of the light-emitting element 120G2 in plan view. The third portion 242c3 is provided between the first portion 242c1 and the second portion 242c2 in plan view and is connected to each of the first portion 242c1 and the second portion 242c2.

[0106] Here, the third portion 242c3 overlaps with the region between the light-emitting region RG1 and the light-emitting region RG2 in plan view and does not overlap with the contact portion 226a. The width W1a of the third portion 242c3 in the direction along the Y-axis is larger than the overlapping width W0 between the coloring layer 241R and the coloring layer 241B, and smaller than the distance L1 between the light-emitting region RG1 and the light-emitting region RG2, similar to the width W1 of the first embodiment.

[0107] On the other hand, each of the first portion 242c1 and the second portion 242c2 does not overlap with the region between the light-emitting region RG1 and the light-emitting region RG2 in plan view and overlaps with the contact portion 226a. The width W1b of each of the first portion 242c1 and the second portion 242c2 in the direction along the Y-axis is larger than the width W1a of the third portion 242c3 in the direction along the Y-axis. The width W1b only needs not to overlap with each light-emitting region in plan view and is appropriately determined according to the shape, size, etc. of each light-emitting region.

[0108] Similarly, the second light-shielding portion 242d has a fourth portion 242d1, a fifth portion 242d2, and a sixth portion 242d3. The fourth portion 242d1 overlaps with the contact portion 226a of the light-emitting element 120R in plan view. The fifth portion 242d2 overlaps with the contact portion 226a of the light-emitting element 120G1 in plan view. The sixth portion 242d3 is provided between the fourth portion 242d1 and the fifth portion 242d2 in plan view and is connected to each of the fourth portion 242d1 and the fifth portion 242d2. Here, the width W2b of each of the fourth portion 242d1 and the fifth portion 242d2 in the direction along the Y-axis is larger than the width W2a of the sixth portion 242d3 in the direction along the Y-axis.

[0109] In the example shown in FIG. 11, the planar shapes of each of the first portion 242c1, the second portion 242c2, the fourth portion 242d1, and the fifth portion 242d2 are quadrilaterals formed by four sides along the X-axis and the Y-axis. Further, in the example shown in FIG. 11, the planar shapes and sizes of the first light-shielding portion 242c and the second light-shielding portion 242d are the same as each other. Note that the planar shapes and sizes of the first light-shielding portion 242c and the second light-shielding portion 242d may be different from each other.

[0110] Also according to the above-described second embodiment, similar to the aforementioned first embodiment, it is possible to reduce the difference between the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB. In the present embodiment, as described above, the width W1b of each of the first portion 242c1 and the second portion 242c2 in the direction along the Y-axis is larger than the width W1a of the third portion 242c3 in the direction along the Y-axis. Therefore, while reducing the excessive light shielding of the light from the light-emitting regions RB and RG2 by the third portion 242c3 of the first light-shielding portion 242c, it is possible to shield the light emission in the vicinity of each contact portion 226a of the light-emitting element 120B and the light-emitting element 120G2 by the first portion 242c1 and the second portion 242c2 of the first light-shielding portion 242c. Also, the width W2b of each of the fourth portion 242d1 and the fifth portion 242d2 in the direction along the Y-axis is larger than the width W2a of the sixth portion 242d3 in the direction along the Y-axis. Therefore, while reducing the excessive light shielding of the light from the light-emitting regions RR and RG1 by the sixth portion 242d3 of the second light-shielding portion 242d, it is possible to shield the light emission in the vicinity of each contact portion 226a of the light-emitting element 120R and the light-emitting element 120G1 by the fourth portion 242d1 and the fifth portion 242d2 of the second light-shielding portion 242d.

[0111] 1C. Third Embodiment The third embodiment will be described. Note that, for elements whose functions are the same as those in the first embodiment in the following respective examples, the reference numerals used in the description of the first embodiment are reused and the detailed description of each is appropriately omitted.

[0112] FIG. 12 is a plan view showing a part of the element substrate 200B in the third embodiment. The element substrate 200B is the same as the element substrate 200 of the first embodiment described above, except that it has a light-shielding portion 242B instead of the light-shielding portion 242. The light-shielding portion 242B is the same as the light-shielding portion 242, except that the planar shape is different. In FIG. 12, among the elements constituting the element substrate 200B, the elements in one pixel P are typically illustrated. Further, in FIG. 12, for the sake of clarity, the illustration of the overcoat layer 250 described later is omitted.

[0113] As shown in FIG. 12, the light-shielding portion 242B has a plurality of first light-shielding portions 242a, a plurality of second light-shielding portions 242b, a plurality of third light-shielding portions 242e, and a plurality of fourth light-shielding portions 242f, and has a ladder shape in plan view.

[0114] The third light-shielding portion 242e is disposed at a position overlapping the region between the light-emitting regions RR and RB and the light-emitting regions RG1 and RG2 within the same pixel P in plan view, extends in the direction along the Y axis, and is connected to each of the first light-shielding portion 242a and the second light-shielding portion 242b. Further, the third light-shielding portion 242e overlaps the overlapping portion of the coloring layers 241R and 241B and the coloring layer 241G within the same pixel P in plan view.

[0115] In the present embodiment, the width W3 of the third light-shielding portion 242e in the direction along the X axis is constant over the entire region in the direction along the Y axis. Here, the width W3 is smaller than the distance L2 between the light-emitting region RR and the light-emitting region RG1, or between the light-emitting region RB and the light-emitting region RG2.

[0116] On the other hand, the fourth light-shielding portion 242f is configured in the same manner as the third light-shielding portion 242e, except that the arrangement is different. Here, the fourth light-shielding portion 242f is disposed at a position overlapping the region between the light-emitting regions RR and RB and the light-emitting regions RG1 and RG2 between different pixels P in plan view, extends in the direction along the Y axis, and is connected to each of the first light-shielding portion 242a and the second light-shielding portion 242b. Further, the fourth light-shielding portion 242f overlaps the overlapping portion of the coloring layers 241R and 241B and the coloring layer 241G between different pixels P in plan view.

[0117] Also according to the third embodiment above, similar to the first embodiment described above, the difference in the light distribution characteristics of the light emitted from the light emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light emitting regions RR and RB can be reduced. In the present embodiment, as described above, the light shielding portion 242B includes the third light shielding portion 242e and the fourth light shielding portion 242f. The third light shielding portion 242e is provided between the first portion 242a1 and the fourth portion 242b1 in a plan view, and is connected to each of the first portion 242a1 and the fourth portion 242b1. The fourth light shielding portion 242f is provided between the second portion 242a2 and the fifth portion 242b2 in a plan view, and is connected to each of the second portion 242a2 and the fifth portion 242b2. By using such a ladder-shaped light shielding portion 242B, even when unintended light emission occurs over the entire outer peripheral edge of each light emitting region, the light emission can be shielded by the light shielding portion 242B.

[0118] 1D. Fourth Embodiment The fourth embodiment will be described. In the following examples, for elements whose functions are the same as those in the first embodiment, the reference numerals used in the description of the first embodiment are reused, and the detailed description of each is appropriately omitted.

[0119] FIG. 13 is a plan view showing a part of the element substrate 200C in the fourth embodiment. The element substrate 200C is the same as the element substrate 200 of the first embodiment described above, except that it has a light shielding portion 242C instead of the light shielding portion 242. The light shielding portion 242C is the same as the light shielding portion 242, except that the shape in a plan view is different. In FIG. 13, among the elements constituting the element substrate 200C, the elements in one pixel P are typically shown. Also in FIG. 13, for the sake of clarity, the illustration of the overcoat layer 250 described later is omitted.

[0120] As shown in FIG. 13, the light shielding portion 242C has a plurality of first light shielding portions 242g and a plurality of second light shielding portions 242h.

[0121] The first light-shielding portion 242g has a first portion 242g1, a second portion 242g2, and a third portion 242g3. Here, the third portion 242g3 is the same as the third portion 242c3 of the second embodiment described above. The first portion 242g1 and the second portion 242g2 are the same as the first portion 242c1 and the second portion 242c2 of the second embodiment described above, except that their planar shapes are different.

[0122] Similarly, the second light-shielding portion 242h has a fourth portion 242h1, a fifth portion 242h2, and a sixth portion 242h3. Here, the sixth portion 242h3 is the same as the sixth portion 242d3 of the second embodiment described above. The fourth portion 242h1 and the fifth portion 242h2 are the same as the fourth portion 242d1 and the fifth portion 242d2 of the second embodiment described above, except that their planar shapes are different.

[0123] In the example shown in FIG. 13, the planar shapes of the first portion 242g1, the second portion 242g2, the fourth portion 242h1, and the fifth portion 242h2 each include four sides inclined with respect to the X-axis and the Y-axis. Also, in the example shown in FIG. 13, the planar shapes and sizes of the first light-shielding portion 242g and the second light-shielding portion 242h are the same as each other. Note that the planar shapes and sizes of the first light-shielding portion 242g and the second light-shielding portion 242h may be different from each other. For example, the planar shapes of the first portion 242g1, the second portion 242g2, the fourth portion 242h1, and the fifth portion 242h2 may each have a rounded portion.

[0124] Also according to the above-described fourth embodiment, similar to the first embodiment described above, it is possible to reduce the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB. In the present embodiment, as described above, the shapes of the first portion 242g1 and the second portion 242g2 are each a shape along the shape between the light-emitting regions. For this reason, it is possible to efficiently block the light emission in the vicinity of each contact portion 226a of the light-emitting element 120B and the light-emitting element 120G2. Similarly, the shapes of the fourth portion 242h1 and the fifth portion 242h2 are each a shape along the shape between the light-emitting regions. For this reason, it is possible to efficiently block the light emission in the vicinity of each contact portion 226a of the light-emitting element 120R and the light-emitting element 120G1.

[0125] 1E. Fifth Embodiment The fifth embodiment will be described. In each of the following examples, for elements whose functions are the same as those in the first embodiment, the reference numerals used in the description of the first embodiment are reused, and the detailed description of each is appropriately omitted.

[0126] FIG. 14 is a plan view showing a part of the element substrate 200D in the fifth embodiment. The element substrate 200D is the same as the element substrate 200 of the first embodiment described above, except that it has a light-shielding portion 242D instead of the light-shielding portion 242. The light-shielding portion 242D is the same as the light-shielding portion 242, except that the planar shape is different. In FIG. 14, among the elements constituting the element substrate 200D, the elements in one pixel P are typically illustrated. Also in FIG. 14, for ease of viewing, the illustration of the overcoat layer 250 described later is omitted.

[0127] As shown in FIG. 14, the light-shielding portion 242D has a plurality of first light-shielding portions 242g, a plurality of second light-shielding portions 242h, a plurality of third light-shielding portions 242e, and a plurality of fourth light-shielding portions 242f, and has a ladder shape in plan view. Here, the respective widths W5 of the first portion 242g1 and the fourth portion 242h1 in the direction along the X-axis are larger than the width W3 of the third light-shielding portion 242e in the direction along the X-axis. Similarly, the respective widths W6 of the second portion 242g2 and the fifth portion 242h2 in the direction along the X-axis are larger than the width of the fourth light-shielding portion 242f in the direction along the X-axis.

[0128] Also according to the above-described fifth embodiment, similar to the aforementioned first embodiment, it is possible to reduce the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB. In this embodiment, as described above, the width W5 is larger than the width W3, and the width W6 is larger than the width W4. For this reason, while reducing the light from each light-emitting region from being shielded more than necessary by the third light-shielding portion 242e and the fourth light-shielding portion 242f, it is possible to shield the light emission in the vicinity of the contact portion 226a by the first light-shielding portion 242g and the second light-shielding portion 242h.

[0129] 1F. Modification Each of the embodiments illustrated above can be variously modified. Specific modification modes applicable to the above-described embodiments are illustrated below. Two or more modes arbitrarily selected from the following illustrations can be appropriately combined within a range that does not conflict with each other. In addition, each modification mode of the first embodiment shown below is appropriately applied to the second embodiment within a range that does not conflict with each other.

[0130] 1F-1. Modification 1 FIG. 15 is a cross-sectional view showing the color layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification 1. Modification 1 is the same as the aforementioned first embodiment except that the thicknesses of the color layers 241R and 241B are different. In Modification 1, the thicknesses of the color layers 241R and 241B are each thicker than the thickness of the light-shielding portion 242, and the thickness of the color layer 241R is thicker than the thickness of the color layer 241B. Also in the above Modification 1, similar to the aforementioned first embodiment, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0131] 1F-2. Modification 2 FIG. 16 is a cross-sectional view showing the color layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification 2. Modification 2 is the same as the aforementioned first embodiment except that the arrangement of the light-shielding portion 242 is different. In Modification 2, the light-shielding portion 242 is arranged on the color layer 241G. Here, the overcoat layer 250 is arranged so as to fill the step formed by the light-shielding portion 242. Also in the above Modification 2, similar to the aforementioned first embodiment, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0132] 1F-3. Modification 3 FIG. 17 is a cross-sectional view showing the color layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification 3. Modification 3 is the same as Modification 2 described above except that the thicknesses of the color layers 241R, 241G, and 241B are different. In Modification 3 , wear the thicknesses of the color layers 241R and 241B are each thicker than the thickness of the light-shielding portion 242 without and the thickness of the color layer 241R is thicker than the thickness of the color layer 241B. Also in the above Modification 3, similar to the aforementioned first embodiment, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0133] 1F-4. Modification Example 4 FIG. 18 is a cross-sectional view showing the colored layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification Example 4. Modification Example 4 is the same as the aforementioned first embodiment except that the cross-sectional shape of the light-shielding portion 242 is different. In Modification Example 4, when viewed in a cross-section orthogonal to the Y-axis, each of the first light-shielding portion 242a and the second light-shielding portion 242b forms a trapezoid such that the width increases in the Z2 direction. Such a light-shielding portion 242 has an advantage that it is difficult for air bubbles to remain between the colored layer 241G and the light-shielding portion 242 when the colored layer 241G is formed after the formation of the light-shielding portion 242. The light-shielding portion 242 having such a cross-sectional shape is formed, for example, by using a positive photosensitive resin material as a constituent material. Also by the above Modification Example 4, similarly to the aforementioned first embodiment, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0134] 1F-5. Modification Example 5 FIG. 19 is a cross-sectional view showing the colored layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification Example 5. Modification Example 5 is the same as the aforementioned Modification Example 4 except that the thicknesses of the colored layers 241R and 241B are different. In Modification Example 5, the thicknesses of the colored layers 241R and 241B are each thicker than the thickness of the light-shielding portion 242, and the thickness of the colored layer 241R is thicker than the thickness of the colored layer 241B. Also by the above Modification Example 5, similarly to the aforementioned first embodiment, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0135] 1F-6. Modification Example 6 FIG. 20 is a cross-sectional view showing the color layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification 6. Modification 6 is the same as the aforementioned Modification 4 except that the arrangement of the light-shielding portion 242 is different. In Modification 6, the light-shielding portion 242 is disposed on the color layer 241G. Here, the overcoat layer 250 is disposed so as to fill the step formed by the light-shielding portion 242. Also in the above Modification 6, similar to the first embodiment described above, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0136] 1F-7. Modification 7 FIG. 21 is a cross-sectional view showing the color layers 241R, 241G, 241B, the light-shielding portion 242, and the overcoat layer 250 of Modification 7. Modification 7 is the same as the aforementioned Modification 6 except that the thicknesses of the color layers 241R, 241G, and 241B are different. In Modification 7 , wear the thicknesses of each of the color layers 241R and 241B are thicker than the thickness of the light-shielding portion 242 without and the thickness of the color layer 241R is thicker than the thickness of the color layer 241B. Also in the above Modification 7, similar to the first embodiment described above, the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB can be reduced.

[0137] 1F-8. Modification 8 FIG. 22 is a plan view showing a part of the element substrate 200E in Modification 8. The element substrate 200E is the same as the element substrate 200 of the first embodiment described above except that it has a light-shielding portion 242E instead of the light-shielding portion 242. The light-shielding portion 242E is the same as the light-shielding portion 242 except that the planar shape is different. In FIG. 22, among the elements constituting the element substrate 200E, the elements in one pixel P are typically illustrated. Also in FIG. 22, for ease of viewing, the illustration of the overcoat layer 250 described later is omitted.

[0138] As shown in FIG. 22, the light-shielding portion 242E has a plurality of first light-shielding portions 242g, a plurality of second light-shielding portions 242h, a plurality of third light-shielding portions 242e, a plurality of fourth light-shielding portions 242f, a plurality of fifth light-shielding portions 242i, and a plurality of sixth light-shielding portions 242j, and forms a lattice pattern in plan view.

[0139] Here, the fifth light-shielding portion 242i is arranged at a position overlapping a region between the light-emitting region RR and the light-emitting region RB within the same pixel P in plan view, X extends in a direction along the axis, and is connected to each of two adjacent first light-shielding portions 242g along the X-axis direction. Further, the fifth light-shielding portion 242i overlaps a overlapping portion between the coloring layer 241R and the coloring layer 241B within the same pixel P in plan view. Note that the fifth light-shielding portion 242i is configured in the same manner as the third portion 242g3 of the first light-shielding portion 242g, except for the different arrangement.

[0140] On the other hand, the sixth light-shielding portion 242j is configured in the same manner as the fifth light-shielding portion 242i, except for the different arrangement. Here, the sixth light-shielding portion 242j is arranged at a position overlapping a region between the light-emitting region RR and the light-emitting region RB between different pixels P in plan view, X extends in a direction along the axis, and is connected to each of two adjacent second light-shielding portions 242h along the X-axis direction. Further, the sixth light-shielding portion 242j overlaps a overlapping portion between the coloring layer 241R and the coloring layer 241B between different pixels P in plan view. Note that the sixth light-shielding portion 242j is configured in the same manner as the sixth portion 242h3 of the second light-shielding portion 242h, except for the different arrangement.

[0141] Also according to the above Modification 8, similar to the aforementioned first embodiment, it is possible to reduce the difference in the light distribution characteristics of the light emitted from the light-emitting regions RG1 and RG2 and the light distribution characteristics of the light emitted from the light-emitting regions RR and RB.

[0142] 1F-9. Modification 9 In the foregoing embodiment, the light-emitting element 120 includes an optical resonance structure having different resonance wavelengths for each color, but it may not include an optical resonance structure. Further, the light-emitting element layer 220 may include, for example, a partition wall that partitions the organic layer 228 for each light-emitting element 120. Further, the light-emitting element 120 may include a different light-emitting material for each sub-pixel P0. Further, the pixel electrode 226 may have light reflectivity. In that case, the reflective layer 222 may be omitted. Further, although the common electrode 229 is common to the plurality of light-emitting elements 120, an individual cathode may be provided for each light-emitting element 120.

[0143] Further, in the foregoing embodiment, a configuration for improving the light distribution characteristics when the viewpoint changes around the X axis is exemplified, but the present invention is not limited to this exemplification. For example, when it is desired to improve the light distribution characteristics when the viewpoint changes around the Y axis, the foregoing configuration may be rotated 90° around the Z axis.

[0144] Further, in the foregoing embodiment, a configuration in which the sub-pixel PG has two light-emitting elements 120G1 and 120G2 is exemplified, but the present invention is not limited to this configuration, and the light-emitting elements 120G1 and 120G2 may be integrated into one light-emitting element. In this case, the light-emitting element is the "third light-emitting element".

[0145] 2. Electronic device The electro-optical device 100 of the foregoing embodiment can be applied to various electronic devices.

[0146] 2-1. Head-mounted display FIG. 23 is a diagram schematically showing an example of an electronic device, a virtual image display device 700. The virtual image display device 700 shown in FIG. 23 is a head-mounted display (HMD) that is mounted on an observer's head and displays an image. The virtual image display device 700 includes the electro-optical device 100 described above, a collimator 71, a light guide 72, a first reflection-type volume hologram 73, a second reflection-type volume hologram 74, and a control unit 79. Note that the light emitted from the electro-optical device 100 is emitted as video light LL. Further, the electro-optical device 100 can apply the configuration of each of the foregoing embodiments or modified examples.

[0147] The control unit 79 includes, for example, a processor and a memory, and controls the operation of the electro-optical device 100. The collimator 71 is disposed between the electro-optical device 100 and the light guide 72. The collimator 71 makes the light emitted from the electro-optical device 100 into parallel light. The collimator 71 is composed of a collimator lens or the like. The light converted into parallel light by the collimator 71 enters the light guide 72.

[0148] The light guide 72 has a flat plate shape and is disposed to extend in a direction intersecting the direction of the light incident through the collimator 71. The light guide 72 reflects and guides light inside thereof. On the surface 721 of the light guide 72 facing the collimator 71, a light incident port for light to enter and a light exit port for light to exit are provided. On the surface 722 of the light guide 72 opposite to the surface 721, a first reflection type volume hologram 73 as a diffractive optical element and a second reflection type volume hologram 74 as a diffractive optical element are disposed. The first reflection type volume hologram 73 is provided closer to the light exit port side than the second reflection type volume hologram 74. The first reflection type volume hologram 73 and the second reflection type volume hologram 74 have interference fringes corresponding to a predetermined wavelength range and diffractively reflect light in the predetermined wavelength range.

[0149] In the virtual image display device 700 having such a configuration, the video light LL incident into the light guide 72 from the light incident port repeats reflections and travels, and is guided from the light exit port to the pupil EY of the observer, so that the observer can observe an image composed of a virtual image formed by the video light LL.

[0150] The above virtual image display device 700 includes the electro-optical device 100 and the control unit 79 that controls the operation of the electro-optical device 100. Therefore, a virtual image display device 700 with light distribution characteristics superior to those of the prior art can be provided.

[0151] Note that the virtual image display device 700 may include a combining element such as a dichroic prism that combines the light emitted from the electro-optical device 100. In this case, the virtual image display device 700 can include, for example, the electro-optical device 100 that emits light in the blue wavelength range, the electro-optical device 100 that emits light in the green wavelength range, and the electro-optical device 100 that emits light in the red wavelength range.

[0152] 2-2. Personal Computer FIG. 24 is a perspective view showing a personal computer 400 which is an example of an electronic device. The personal computer 400 shown in FIG. 24 includes the electro-optical device 100, a main body portion 403 provided with a power switch 401 and a keyboard 402, and a control unit 409. The control unit 409 includes, for example, a processor and a memory, and controls the operation of the electro-optical device 100. Since the personal computer 400 includes the electro-optical device 100 described above, it has excellent quality. Note that the electro-optical device 100 can adopt the configurations of the above-described embodiments or modifications.

[0153] Note that examples of the “electronic device” including the electro-optical device 100 include devices that are arranged close to the eyes, such as a digital scope, digital binoculars, digital still camera, and video camera, in addition to the virtual image display device 700 illustrated in FIG. 23 and the personal computer 400 illustrated in FIG. 24. Further, the “electronic device” including the electro-optical device 100 is applied to a mobile phone, a smartphone, a PDA (Personal Digital Assistants), a car navigation device, and a display unit for vehicle use. Furthermore, the “electronic device” including the electro-optical device 100 is applied as illumination for illuminating light.

[0154] As described above, the present invention has been described based on the illustrated embodiments, but the present invention is not limited to these. In addition, the configuration of each part of the present invention can be replaced with any configuration that exhibits the same function as that of the above-described embodiments, and any configuration can also be added.
