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 (33)

1. An electronic apparatus comprising:

a first light-emitting element that emits first light;

a second light-emitting element that emits second light;

a first color filter through which the first light passes; and

a second color filter through which the second light passes, wherein

the first light-emitting element and the second light-emitting element are arranged along a first direction, and

in a cross-sectional view along the first direction, a width in the first direction of a portion of the first color filter that overlaps in a second direction perpendicular to the first direction with the first light-emitting element is larger than a width in the first direction of a portion of the second color filter that overlaps in the second direction with the second light-emitting element.

2. The electronic apparatus according to claim 1 , wherein

the first direction is along a direction from a center of a display region toward an outside of the display region in a plan view.

3. The electronic apparatus according to claim 2 , wherein

in the plan view, a center of the first color filter is disposed closer to the center of the display region than a center of the first light-emitting element.

4. The electronic apparatus according to claim 1 , further comprising:

a lens; and

a light guiding member provided on an opposite side of the lens from the first color filter.

5. The electronic apparatus according to claim 2 , further comprising:

a lens; and

a light guiding member provided on an opposite side of the lens from the first color filter.

6. An electronic apparatus comprising:

a first light-emitting element that emits first light;

a second light-emitting element that emits second light;

a first color filter through which the first light passes; and

a second color filter through which the second light passes, wherein

in a cross-sectional view along a first direction, the first color filter is offset in the first direction with respect to the first light-emitting element, and the second color filter is offset in a direction opposite to the first direction with respect to the second light-emitting element.

7. The electronic apparatus according to claim 6 , wherein

the first direction is along a direction from a center of the display region toward an outside of the display region in a plan view.

8. The electronic apparatus according to claim 6 , further comprising:

a lens; and

a light guiding member provided on an opposite side of the lens from the first color filter.

9. The electronic apparatus according to claim 7 , further comprising:

a lens; and

a light guiding member provided on an opposite side of the lens from the first color filter.

10. The electronic apparatus according to claim 6 , wherein

in the cross-sectional view along the first direction, a width in the first direction of a portion of the first color filter that overlaps in a second direction perpendicular to the first direction with the first light-emitting element is larger than a width in the first direction of a portion of the second color filter that overlaps in the second direction with the second light-emitting element.
