Abstract

The display device includes the first light-emitting element, a second light-emitting element, a first color filter through which light from the first light-emitting element passes, and a second color filter through which the light from the second light-emitting element passes. The relative positional relationship between the center of the first light-emitting element and the center of the first color filter is different from the relative positional relationship between the center of the second light-emitting element and the center of the second color filter.

Claims (17)

1. A display device comprising:

a first light-emitting element;

a second light-emitting element;

a light collection optical system;

a first color filter through which light from the first light-emitting element passes, the first color filter being located between the first light-emitting element and the light collection optical system; and

a second color filter through which light from the second light-emitting element passes, the second color filter being located between the second light-emitting element and the light collection optical system, wherein,

a first optical axis passing through a center of the first color filter from a center of the first light-emitting element is inclined to a second optical axis passing through a center of the second color filter from a center of the second light-emitting element, and

light of the first optical axis and light of the second optical axis are collected by the light collection optical system.

2. The display device according to claim 1 , wherein

the first light-emitting element, the first color filter, the second light-emitting element, and the second color filter are arranged in a display region,

the first optical axis is inclined to a center side of the display region from a normal line with respect to the first light-emitting element, and

the center of the first color filter in plan view is deviated to the center side of the display region further than the center of the first light-emitting element in plan view.

3. The display device according to claim 2 , wherein

the second light-emitting element and the second color filter are arranged further inside the display region than the first light-emitting element and the first color filter, and

when a deviation amount of the center of the first light-emitting element and the center of the first color filter in plan view is a first deviation amount, and a deviation amount of the center of the second light-emitting element and the center of the second color filter in plan view is a second deviation amount, the second deviation amount is smaller than the first deviation amount.

4. An electronic apparatus comprising:

a display device according to claim 1 .
