Electro-optical device substrate, electro-optical device, and electronic apparatus

1. An electro-optical device substrate comprising:

a first transparent substrate;

a second transparent substrate that faces the first transparent substrate, the second transparent substrate including recesses in non-aperture regions of a surface of the second transparent substrate that faces the first transparent substrate, the recesses causing light that is incident to the non-aperture regions to refract toward aperture regions; and

an adhesive that bonds the first and second transparent substrates together.

2. The electro-optical device substrate according to claim 1 , wherein the adhesive is disposed inside the recesses.

3. The electro-optical device substrate according to claim 1 , wherein the adhesive is disposed at least in the aperture regions and the non-aperture regions between the first and second transparent substrates.

4. The electro-optical device substrate according to claim 1 , wherein a light-shielding film is formed at least in portions of the non-aperture regions of a surface of the second transparent substrate that is opposite the surface of the second transparent substrate facing the first transparent substrate.

5. The electro-optical device substrate according to claim 4 , wherein the recesses are formed at least in light-shielding portions of the non-aperture regions, the light-shielding portions being portions where the light-shielding film is formed.

6. The electro-optical device substrate according to claim 5 ,

wherein the light-shielding film is formed as a grid pattern defining the non-aperture regions, and

wherein the recesses are formed in the light-shielding portions.

7. An electro-optical device comprising the electro-optical device substrate according to claim 1 .

8. An electronic apparatus comprising the electro-optical device according to claim 7 .
