Abstract

According to an aspect, a display apparatus includes: a substrate; a plurality of pixels disposed on the substrate; a plurality of inorganic light emitting elements that are provided in the pixels, respectively; an electrode that is translucent and provided on one surface side of the substrate and that is coupled to one of the inorganic light emitting elements; a first conductive layer that is translucent and provided on the one surface side of the substrate and that covers the electrode; and a cover member that is translucent and provided on the one surface side of the substrate and that covers the first conductive layer. A sheet resistance value of the first conductive layer is higher than a sheet resistance value of the electrode.

Claims (31)

1. A display apparatus comprising:

a substrate;

a plurality of pixels disposed on the substrate;

a plurality of inorganic light emitting elements that are provided in the pixels, respectively;

an electrode that is translucent and provided on one surface side of the substrate and that is coupled to one of the inorganic light emitting elements;

a first conductive layer that is translucent and provided on the one surface side of the substrate and that covers the electrode; and

a cover member that is translucent and provided on the one surface side of the substrate and that covers the first conductive layer, wherein

a sheet resistance value of the first conductive layer is higher than a sheet resistance value of the electrode.

2. The display apparatus according to claim 1 , wherein the first conductive layer bonds the cover member to the one surface side of the substrate.

3. The display apparatus according to claim 1 , further comprising:

a light-shielding second conductive layer that is provided on the one surface side of the substrate and that is coupled to the first conductive layer, wherein

the substrate includes

a display region in which the pixels are arranged, and

a peripheral region located outside the display region, and

the second conductive layer is arranged in the peripheral region.

4. The display apparatus according to claim 1 , further comprising a circularly polarizing plate provided between the substrate and the cover member.

5. The display apparatus according to claim 1 , further comprising:

a circularly polarizing plate provided between the substrate and the cover member, and

an adhesion layer, wherein

the adhesion layer is provided between the substrate and the circularly polarizing plate and bonds the circularly polarizing plate to the one surface side of the substrate, and

a sheet resistance value of the adhesion layer is higher than the sheet resistance value of the electrode.

6. The display apparatus according to claim 1 , further comprising a third conductive layer provided on another surface side of the substrate that is located on an opposite side from the one surface.

7. The display apparatus according to claim 6 , further comprising a light-shielding fourth conductive layer that is arranged on a side surface of the substrate and that is coupled to the third conductive layer.

8. The display apparatus according to claim 1 , further comprising a light-shielding conductive layer provided between the electrode and the cover member,

an opening located in a region that overlaps with the one of the inorganic light emitting elements in a plan view is provided in the first conductive layer, and

a sheet resistance value of the light-shielding conductive layer is higher than the sheet resistance value of the electrode.

9. The display apparatus according to claim 1 , further comprising:

a transistor that is provided on the one surface side of the substrate and that is coupled to the one of the inorganic light emitting elements; and

wiring provided on the one surface side of the substrate, wherein

a first capacitor is formed between the transistor and the one of the inorganic light emitting elements, and

a second capacitor is formed between the wiring and the one of the inorganic light emitting elements.
