## Abstract

There is provided an electro-optical device including a first pixel, a second pixel, a third pixel, a first light shielding portion provided between the first pixel and the second pixel, a second light shielding portion provided between the second pixel and the third pixel, in which a width of the first light shielding portion and a width of the second light shielding portion are different.

## Claims

### Claim 1

An electro-optical device comprising:
a first pixel;
a second pixel;
a third pixel;
a first color filter covering a light emitting region of the first pixel;
a second color filter covering a light emitting region of the second pixel;
a third color filter covering a light emitting region of the third pixel, the second color filter having a projection portion that projects toward the light emitting region of the first pixel;
a first light shielding portion provided between the first pixel and the second pixel, the first light shielding portion being the projection portion; and
a second light shielding portion provided between the second pixel and the third pixel,
wherein the second light shielding portion does not project toward the light emitting region of the second pixel, and
wherein a width of the first light shielding portion and a width of the second light shielding portion are different.

### Claim 2 (depends on 1)

The electro-optical device according to claim 1,
wherein each of the first pixel, the second pixel and the third pixel includes a light emitting element,
wherein a current value of a current supplied to the light emitting element of the first pixel is the lowest among the current values of the currents supplied to each light emitting element when displaying a white color, and
wherein the width of the first light shielding portion is larger than the width of second light shielding portion.

### Claim 3 (depends on 2)
