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. A display device comprising:

a first pixel having a first light-emitting element and a first color filter through which light from the first light-emitting element passes; and

a second pixel having a second light-emitting element and a second color filter through which the light from the second light-emitting element passes,

wherein a relative positional relationship between a center of the first light-emitting element and a center of the first color filter in plane view is different from a relative positional relationship between a center of the second light-emitting element and a center of the second color filter in plane view,

an optical axis of a first video light from the first pixel is set by the relative positional relationship between the center of the first light-emitting element and the center of the first color filter in plane view, and

an optical axis of a second video light from the second pixel is set by the relative positional relationship between the center of the second light-emitting element and the center of the second color filter in plane view.

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,

an optical axis of the first light-emitting element 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 plane view is deviated to the center side of the display region further than the center of the first light-emitting element in plane view.

3. The display device according to claim 2 , wherein

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

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

4. The display device according to claim 3 , further comprising:

a separation portion that separates the first color filter and the second color filter,

wherein a difference between the first deviation amount and the second deviation amount is made by a width of the separation portion.

5. The display device according to claim 3 , wherein

the first and second color filters each include a red color filter, a green color filter, and a blue color filter, and

the difference between the first deviation amount and the second deviation amount is made by a width of a separation portion which is arranged between the first color filter and the second color filter and separates the red color filter of the first color filter and the blue color filter of the second color filter.

6. The display device according to claim 4 , wherein

a plurality of color filters, including the first and second color filters, is arranged in the display region in a matrix having a first row and a second row adjacent to the first row,

at least one of the separation portion is arranged in each of the first row and the second row, between color filters, and

a position in a row direction of the at least one separation portion in the first row is different from a position in the row direction of the at least one separation portion in the second row.

7. The display device according to claim 3 , wherein the difference between the first deviation amount and the second deviation amount is made by a width of another color filter arranged between the first color filter and the second color filter.

8. The display device according to claim 7 , wherein

the first color filter and second color filter each include a red color filter, a green color filter, and a blue color filter, and

the other color filter is the blue color filter of the second color filter.

9. The display device according to claim 7 , wherein

a plurality of color filters, including the first and second color filters, is arranged in the display region in a matrix having a first row and a second row adjacent to the first row,

at least one of the other color filter, which sets a difference between deviation amounts of color filters and light-emitting elements, is arranged in each of the first row and the second row; and

a position in a row direction of the at least one other color filter in the first row is different from a position in the row direction of the at least one other color filter in the second row.

10. An electronic apparatus comprising:

the display device according to claim 1 .
