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

For the sake of convenience, the X-axis, Y-axis, and Z-axis that are 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 opposite direction to the X1 direction is the X2 direction. Similarly, one direction along the Y axis is the Y1 direction, and the opposite direction to the Y1 direction is the Y2 direction.

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

As shown in FIG. 1, the electro-optical device 100 has an element substrate 200 and a translucent substrate 300 having optical transparency. The electro-optical device 100 has a so-called top emission structure. The electro-optical device 100 emits light from the translucent substrate 300 . The term "light transmissivity" means transparency to visible light, and preferably the visible light transmittance is 50% or more.

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 .

Although not shown, the external terminals 104 are connected to an FPC (Flexible printed circuits) board or the like for electrical connection with a higher-level circuit. A power supply circuit (not shown) is electrically connected to the element substrate 200 .

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

FIG. 2 is an equivalent circuit diagram of the sub-pixel P0 shown in FIG. FIG. 2 representatively shows one sub-pixel P0 and its corresponding elements. As shown in FIG. 2 , the element substrate 200 is provided with a plurality of scanning lines 111 , a plurality of data lines 112 , a plurality of feeder lines 113 and a plurality of feeder lines 114 .

The scanning lines 111 extend along the X-axis, while the data lines 112 extend 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. 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.

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

The power supply line 113 is electrically connected to the pixel electrode 226 via the pixel circuit 130 . On the other hand, the common electrode 229 is electrically connected to the feed line 114 . Here, the power supply line 113 is supplied with a high power supply potential Vel from a power supply circuit (not shown). The power supply line 114 is supplied with a low power supply potential Vct 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, whereby the organic layer 228 emits light.

One of both electrodes of the storage capacitor 133 is connected to the gate of the driving transistor 132 and the other is connected to the power supply line 113 .

In the pixel circuit 130 described above, when the scanning line driving circuit 102 activates the scanning signal to select the scanning line 111, 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 the light emitting element 120 with a current corresponding to the potential of the supplied data signal, that is, the potential difference between the gate and the source. As a result, the light-emitting element 120 emits light with luminance corresponding to the magnitude of the current supplied from the driving transistor 132 . After that, when the scanning line driver circuit 102 deselects 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 storage capacitor 133 . Therefore, the light emission of the light emitting element 120 can be maintained even after the switching transistor 131 is turned off.

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

In the examples shown in FIGS. 4 and 5, the reflective layer 222 also functions as wiring. Although not shown, the wiring is electrically connected to, for example, the pixel circuit 130 described above. Note that the reflective layer 222 does not have to function as the wiring.

The second distance adjustment layer 225b is arranged in the sub-pixels PR and PG among the sub-pixels PR, PG and PB, and is not arranged in the sub-pixel PB. Therefore, the first distance adjustment layer 225a and the second distance adjustment layer 225b are arranged in the sub-pixel PR. Among the first distance adjustment layer 225a and the second distance adjustment layer 225b, the second distance adjustment layer 225b is arranged in the sub-pixel PG. Neither the first distance adjustment layer 225a nor the second distance adjustment layer 225b is arranged in the sub-pixel PB.

Each of the pixel electrodes 226R, 226G and 226B is a layer provided for each sub-pixel P0 and having electrical conductivity and optical transparency.

The pixel electrode 226R is the pixel electrode 226 provided in the sub-pixel PR. The pixel electrode 226G is the pixel electrode 226 provided in the sub-pixel PG. The pixel electrode 226B is the pixel electrode 226 provided in the sub-pixel PB. Note that the pixel electrode 226R is an example of the "first pixel electrode". The pixel electrode 226G is an example of a "second pixel electrode".

The element isolation layer 227 is an insulating layer covering the outer edge of each of the pixel electrodes 226R, 226G 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, 226G and 226B into contact with the organic layer 228. FIG. The plurality of openings define light emitting regions RR, RG and RB.

Here, the contact area between the pixel electrode 226R and the organic layer 228 is equal to the light emitting area RR in plan view.

A contact area between the pixel electrode 226B and the organic layer 228 is equal to the light emitting area RB in plan view.

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 this embodiment, the light-emitting layer includes, for example, a light-emitting layer that emits red light, a light-emitting layer that emits green light, and a light-emitting layer that emits blue light. are appropriately laminated. Therefore, the organic layer 228 realizes white light or a color similar thereto. In addition, the organic layer 228 can apply a known structure and material.

The light emitting element 120G has the same layer configuration as the light emitting element 120R except that the first distance adjustment layer 225a is omitted and the pixel electrode 226G is provided instead of the pixel electrode 226R. The light emitting element 120B has the same layer configuration as the light emitting element 120R except that the first distance adjusting layer 225a and the second distance adjusting layer 225b are omitted and the pixel electrode 226B is provided instead of the pixel electrode 226R.

Here, the distance between the reflective layer 222 and the common electrode 229 differs for each sub-pixel P0.

The distance in the sub-pixel PG is the distance L0G set corresponding to the green wavelength range. The distance in the sub-pixel PB is the distance L0B set corresponding to the blue wavelength range.

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

The resonant wavelength in the optical resonant structure described above 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 relational expression [1] represents the sum of phase shifts occurring 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]

The optical distance L0 is set so that the peak wavelength of the light in the wavelength band desired to be extracted is 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.

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

The adhesion layer 240 is a light-transmissive layer for enhancing adhesion between the sealing layer 230 and the light shielding portion 250 . The adhesion layer 240 is made of, for example, a resin material such as epoxy resin. Note that the thickness of the adhesion layer 240 is not particularly limited and is arbitrary.

The light shielding part 250 is a light shielding layer for shielding unnecessary light from the light emitting regions RR, RG and RB. Here, the light shielding portion 250 has a first surface F1 facing the Z2 direction and a second surface F2 facing the Z1 direction.

The light shielding part 250 preferably has not only a light shielding property but also a light absorbing property or an antireflection property, and is made of a resin material such as an acrylic photosensitive resin material containing a coloring material such as a pigment or a dye. .

Also, the widths of the third light shielding portion 253 and the fourth light shielding portion 254 in the direction along the X axis are equal to each other. The width of each of the third light shielding portion 253 and the fourth light shielding portion 254 in the direction along the X-axis may not be constant over the entire area in the direction along the Y-axis, and may be partially thickened or thinned. You may Also, the widths of the third light shielding portion 253 and the fourth light shielding portion 254 in the direction along the X axis may be different from each other.

In this embodiment, as shown in FIGS. 4 and 5, each of the third light shielding portion 253 and the fourth light shielding portion 254 has a width that decreases in the Z2 direction when viewed in a cross section perpendicular to the Y axis. form a trapezoid. Similarly, as shown in FIG. 6, the second light shielding portion 252 has a trapezoidal shape such that the width decreases in the Z2 direction when viewed in a cross section perpendicular to the X axis. Although not shown, the first light shielding portion 251 has a trapezoidal shape such that the width decreases in the Z2 direction when viewed in a cross section orthogonal to the X axis.

The cross section, which is a cross section perpendicular to the length direction of each of the first light shielding portion 251, the second light shielding portion 252, the third light shielding portion 253, and the fourth light shielding portion 254 as described above, is the side based on the first surface F1. , a side based on the second face F2. In the cross section, the length of the side based on the first surface F1 is shorter than the length of the side based on the second surface F2. Therefore, it is possible to increase the viewing angle of each sub-pixel P0 while shielding abnormal light emission near the periphery of each light-emitting region. The light shielding portion 250 having such a cross-sectional shape is formed by using, for example, a negative photosensitive resin material as a constituent material.

Note that the cross-sectional shape of the light shielding portion 250 is not limited to a shape in which the width continuously decreases in the Z2 direction, and may be a shape in which the width gradually decreases in the Z2 direction, for example. Also, the cross-sectional shape of the light shielding portion 250 may be rectangular or trapezoidal so that the width decreases in the Z1 direction.

The light shielding portion 250 includes a first opening 255R that overlaps the light emitting region RR in plan view, a second opening 255B that overlaps the light emitting region RB in plan view, and a third opening that overlaps the light emitting region RG in plan view. 255G and are provided. Therefore, light from each corresponding light emitting region can be emitted to the outside of the element substrate 200 through each of these openings.

The resin layer 260 is a light transmissive layer that covers the light shielding section 250 so as to fill the openings of the light shielding section 250 . Here, the resin layer 260 has a third surface F3 facing the Z2 direction and a fourth surface F4 facing the Z1 direction. The resin layer 260 is substantially colorless and transparent, and is made of, for example, a resin material such as an acrylic photosensitive resin material that does not substantially contain a coloring material. The term "substantially colorless and transparent" is a concept that includes not only being completely colorless and transparent, but also being colored and transparent to a degree that is unavoidable in manufacturing. Since the resin layer 260 is substantially transparent, loss of light passing through each opening of the light shielding section 250 can be reduced.

Here, the resin layer 260 is a flattening layer for alleviating unevenness caused by the light shielding portion 250 and flattening. Therefore, the surface of the resin layer 260 facing the Z2 direction has a shape along the light shielding portion 250, whereas the fourth surface F4 of the resin layer 260 facing the Z1 direction is substantially flat. A “substantially flat surface” is a concept that includes not only a flat surface but also a substantially flat surface that is regarded as a flat surface. By providing such a resin layer 260, it is possible to improve the adhesiveness between the element substrate 200 and the translucent substrate 300, and to reduce unwanted reflection at the interface between these substrates.

Here, based on FIG. 6, the contact portion 226a will be described. As shown in FIG. 6, a relay electrode 271 is arranged between the first insulating layer 224a and the second insulating layer 224b of the insulating layer 224, and the pixel electrode 226 extends through the distance adjusting layer 225. It has a contact portion 226 a connected to the relay electrode 271 . The relay electrode 271 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 271 is provided for each light emitting element 120 and arranged at a position not overlapping the light emitting regions RR, RG and RB in plan view. Examples of the constituent material of the relay electrode 271 include conductive materials such as tungsten (W), titanium (Ti), and titanium nitride (TiN).

In the example shown in FIG. 6, an insulating layer 272 is arranged between the relay electrode 271 and the first insulating layer 224a, and the relay electrode 271 passes through the insulating layer 272 and the first insulating layer 224a to reflect the light. connected to layer 222; The insulating layer 272 is composed of, for example, a silicon oxide film. 6 representatively illustrates the pixel electrode 226 and the relay electrode 271 of the light emitting element 120G. It is configured similarly to the electrode 271 .

Here, the relay electrode 271 corresponding to the light emitting element 120R is an example of the "first relay electrode". The relay electrode 271 corresponding to the light emitting element 120G is an example of the "second relay electrode". Also, the contact portion 226a of the pixel electrode 226 of the light emitting element 120R is an example of the "first contact portion". The contact portion 226a of the pixel electrode 226 of the light emitting element 120G is an example of the "second contact portion".

In the configuration in which the relay electrode 271 is provided as described above, the thickness of the organic layer 228 tends to be thin near the periphery of each light-emitting region due to the step due to the contact portion 226a and the isolation layer 227 . Therefore, when the light emitting element 120 is driven with a low current, the peripheral portion of each light emitting region tends to emit light preferentially compared to the central portion. Such light emission near the periphery of each light emitting region resonates at a frequency different from the intended resonance frequency in the above-described optical resonance structure, which causes color shift. Therefore, it is desirable to block such light emission with the light blocking portion 250 . In particular, when the electro-optical device 100 is used as a microdisplay, since the pixels are small, the ratio of the peripheral portion to the original light-emitting region increases, which may cause the above-described color shift with respect to the normal light-emitting amount. Therefore, it is desirable to block the abnormal light emission.

Note that the above-described abnormal light emission resonates at an optical distance that is longer by the thickness of the device isolation layer 227, so it tends to be red. In addition, when the thickness of the organic layer 228 is reduced, the excitation energy is likely to move within the organic layer 228. In this respect as well, it can be said that the above-described abnormal light emission is likely to be red.

1-3. Operation of Light Blocking Section 250 FIG. 7 is a diagram showing a simulation result for explaining the effect of the light blocking section 250. FIG. FIG. 7 shows simulation results of luminance efficiency, color gamut, and luminance viewing angle for the electro-optical devices of Example 1 and Comparative Examples 1 to 3. In FIG. The luminance efficiency indicates efficiency of white luminance with respect to input current. The color gamut indicates an area ratio to the sRGB color gamut. The luminance viewing angle indicates the ratio of luminance at a 20° viewing angle to front luminance.

Here, the electro-optical device of Example 1 is the above-described electro-optical device 100 . The electro-optical device of Comparative Example 1 is the same as the above-described electro-optical device 100 except that the light shielding portion 250 is omitted. The electro-optical device of Comparative Example 2 is the same as the above-described electro-optical device 100 except that the light shielding portion 250 is omitted and color filters are added. The electro-optical device of Comparative Example 3 is the same as the above-described electro-optical device 100 except that a color filter is added.

As shown in FIG. 7, in Example 1, it is possible to achieve a luminance efficiency and a luminance viewing angle close to those of Comparative Example 1 while realizing a color gamut close to those of Comparative Examples 2 and 3.

1-4. Summary of Embodiments As described above, the electro-optical device 100 includes the light emitting element 120R that is an example of the "first light emitting element", the light emitting element 120B that is an example of the "second light emitting element", and the light shielding portion 250. And prepare. The light emitting element 120R includes a common electrode 229 that is an example of a "first electrode" and a reflective layer 222R that is an example of a "first reflective layer". The reflective layer 222R is arranged at a position where the optical distance L0 with respect to the common electrode 229 is the first optical distance. The light emitting element 120B includes a common electrode 229, which is an example of a "second electrode provided integrally with the first electrode," and a reflective layer 222B, which is an example of a "second reflective layer." The reflective layer 222B is arranged at a position where the optical distance L0 to the common electrode 229 is a second optical distance different from the first optical distance. The light shielding part 250 is arranged between the light emitting region RR of the light emitting element 120R and the light emitting region RB of the light emitting element 120B in plan view.

Moreover, the layer in contact with the light shielding portion 250 is substantially colorless and transparent. In particular, in the electro-optical device 100, colored layers such as color filters do not overlap the light emitting regions RR and RB in plan view.

In the electro-optical device 100 described above, the light emitting element 120R emits light in a wavelength range corresponding to the first optical distance due to resonance between the common electrode 229 and the reflective layer 222R. The light emitting element 120B emits light in a wavelength range corresponding to the second optical distance due to resonance between the second electrode and the reflective layer 222B. In addition, the light blocking section 250 can block abnormal light emission near the outer periphery of the light emitting regions of the light emitting elements 120R and 120B. Therefore, even if the layer in contact with the light shielding portion 250 is substantially colorless and transparent, light in a desired wavelength range can be extracted from the light emitting elements 120R and 120B through the layer without providing a color filter. . In this way, since it is not necessary to provide a color filter that causes luminance attenuation when extracting light from each of the light emitting elements 120R and 120B, light in a desired wavelength range can be efficiently extracted from each of the light emitting elements 120R and 120B. be able to.

Here, as described above, the light shielding portion 250 includes the first opening 255R that overlaps the light emitting region RR of the light emitting element 120R in plan view, and the second opening 255B that overlaps the light emitting region RB of the light emitting element 120B in plan view. , has A substantially colorless and transparent resin layer 260 is provided in each of the first opening 255R and the second opening 255B. The resin layer 260 is an example of a layer in contact with the light blocking section 250 .

Further, as described above, the light shielding portion 250 has the first surface F1 and the second surface F2 opposite to the first surface F1. The first surface F1 is positioned between the second surface F2 and the common electrode 229 . The cross section of the light shielding portion 250 has sides based on the first surface F1 and sides based on the second surface F2. Here, the side length W1 based on the first surface F1 is shorter than the side length W2 based on the second surface F2. Therefore, the viewing angle characteristics can be improved compared to a configuration in which the length W1 of the side based on the first surface F1 is longer than the length W2 of the side based on the second surface F2.

Here, as described above, the electro-optical device 100 includes the relay electrodes 271 and the insulating layer 272 of the light emitting elements 120R and 120G. The light emitting element 120R has a pixel electrode 226R as an example of a "first pixel electrode", and a relay electrode 271 as an example of a "first relay electrode" is electrically connected to the pixel electrode 226R. The light emitting element 120G has a pixel electrode 226G as an example of a "second pixel electrode", and a relay electrode 271 as an example of a "second relay electrode" is electrically connected to the pixel electrode 226G. The insulating layer 272 is provided between the pixel electrode 226R and the relay electrode 271 as the first relay electrode and between the pixel electrode 226G and the relay electrode 271 as the second relay electrode. The pixel electrode 226R has a contact portion 226a as a first contact portion that penetrates the insulating layer 272 and is electrically connected to the relay electrode 271 as the first relay electrode. The pixel electrode 226G has a contact portion 226a as a second contact portion that penetrates the insulating layer 272 and is electrically connected to the relay electrode 271 as a second relay electrode. The second surface F2 includes the contact portion 226a as the first contact portion and the contact portion 226a as the second contact portion in plan view. Therefore, the viewing angle characteristics can be improved while the light blocking portion 250 blocks abnormal light emission near the contact portions 226a of the light emitting elements 120R and 120B.

Further, as described above, the resin layer 260 has the third surface F3 and the fourth surface F4 opposite to the third surface F3. The third surface F3 is positioned between the fourth surface F4 and the common electrode 229 . A resin layer 260 covers the light shielding portion 250, and the fourth surface F4 is a flat surface. In this manner, the resin layer 260 is a planarization layer for alleviating unevenness caused by the light shielding portion 250 and planarizing the surface. Therefore, the resin layer 260 and the translucent substrate 300 for the cover can be preferably adhered.

The electro-optical device 100 also includes the sealing layer 230 and the adhesion layer 240 as described above. An encapsulation layer 230 is disposed between the common electrode 229 and the second electrode and the light blocking portion 250 . The adhesion layer 240 is arranged between the sealing layer 230 and the light shielding portion 250 so as to be in contact with the light shielding portion 250 and contains a resin. Therefore, the bonding strength between the light shielding portion 250 and the sealing layer 230 can be increased.

In addition, as described above, the distance between the light emitting region RR of the light emitting element 120R and the light emitting region RB of the light emitting element 120B is smaller than the thickness t of the sealing layer 230 in plan view. The shorter the inter-pixel pitch, the greater the influence of abnormal light emission near the periphery of the light emitting region on normal light emission. In particular, in a configuration where the pitch between pixels is short such that the distance between the light emitting region RR of the light emitting element 120R and the light emitting region RB of the light emitting element 120B is smaller than the thickness of the sealing layer in plan view, normal light emission cannot be obtained. Therefore, the influence of abnormal light emission becomes conspicuous near the periphery of the light emitting region. Therefore, in such a case, it is desired that the abnormal light emission is blocked by the light blocking section 250 .
