Abstract

A display panel includes first display regions, and a second display region between the two first display regions. Each of the first display regions includes first pixels. The second display region includes second pixels disposed in a second direction intersecting a first direction. Each of the second pixels include a first color light-emitting element, a second color light-emitting element, and a third color light-emitting element which are disposed in the first direction. An arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the first pixels may be different from an arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the second pixels.

Claims (32)

1. A display panel comprising:

two first display regions spaced apart in a first direction; and

a second display region between the two first display regions, wherein

each of the two first display regions includes first pixels,

the second display region includes second pixels disposed in a second direction intersecting the first direction, each second pixel having positioned on each side in the first direction an adjacent first pixel directly facing said each second pixel,

the first pixels and the second pixels each include:

a first color light-emitting element;

a second color light-emitting element; and

a third color light-emitting element,

the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the second pixels are disposed in the first direction,

an arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the first pixels is different from an arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the second pixels.

2. The display panel of claim 1 , wherein a minimum distance between two adjacent light-emitting elements among the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the first pixels is greater than a minimum distance between two adjacent light-emitting elements among the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the second pixels.

3. The display panel of claim 1 , wherein

the second color light-emitting element of each of the first pixels is spaced apart from the first color light-emitting element in the second direction, and

the third color light-emitting element of each of the first pixels is spaced apart from the first color light-emitting element in the first direction.

4. The display panel of claim 3 , wherein a center in the second direction of the first color light-emitting element of each of the second pixels is spaced apart from a center in the second direction of the second color light-emitting element of each of the second pixels.

5. The display panel of claim 4 , wherein a center in the second direction of the first color light-emitting element of each of the first pixels is aligned, in the first direction, with the center in the second direction of the first color light-emitting element of each of the second pixels.

6. The display panel of claim 1 , wherein light-emitting regions of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element have different areas relative to each other.

7. The display panel of claim 1 , wherein light-emitting regions of the first color light-emitting element of each of the first pixels and the first color light-emitting element of each of the second pixels have different shapes.

8. The display panel of claim 7 , wherein the light-emitting regions of the first color light-emitting element of each of the first pixels and the first color light-emitting element of each of the second pixels have substantially a same area.

9. The display panel of claim 1 , wherein

the first pixels define n×m pixel rows and pixel columns, where n and m are each a natural number equal to or greater than 2, and

a light-emitting layer of the third color light-emitting element of the first pixel disposed on an i-th pixel row, where i is a natural number equal to or greater than 1, and less than n, and a j-th pixel column, where j is a natural number equal to or greater than 1, and less than m, and a light-emitting layer of the third color light-emitting element of the first pixel disposed on an (i+1)-th pixel row and the j-th pixel column are integral with each other.

10. The display panel of claim 9 , wherein a center in the second direction of the third color light-emitting element of the first pixel disposed on the i-th pixel row and the j-th pixel column, and a center in the second direction of the third color light-emitting element of a first pixel disposed on the i-th pixel row and the (j+1)-th pixel column are spaced apart from each other in the second direction.

11. The display panel of claim 9 , wherein

a light-emitting layer of the third color light-emitting element of the first pixel disposed on an (i−1)-th pixel row and the j-th pixel column, and the light-emitting layer of the third color light-emitting element of the first pixel disposed on the i-th pixel row and the j-th pixel column are spaced apart from each other in the second direction, and

a distance between the third color light-emitting element of the first pixel disposed on the i-th pixel row and the j-th pixel column, and the third color light-emitting element of the first pixel disposed on the (i+1)-th pixel row and the j-th pixel column is less than a distance between the third color light-emitting element of the first pixel disposed on the (i−1)-th pixel row and the j-th pixel column, and the third color light-emitting element of the first pixel disposed on the i-th pixel row and the j-th pixel column.

12. The display panel of claim 1 , wherein

the first pixels define n×m pixel rows and pixel columns, where n and m are each a natural number equal to or greater than 2, and less than n, and

a light-emitting layer of the third color light-emitting element of a first pixel disposed on an i-th pixel row, where i is a natural number equal to or greater than 1, and less than n, and a j-th pixel column, where j is a natural number equal to or greater than one, and less than m, to a light-emitting layer of the third color light-emitting element of a first pixel disposed on an (i+3)-th pixel row and the j-th pixel column are integral with each other.

13. The display panel of claim 1 , wherein among the second pixels, a light-emitting layer of the first color light-emitting element of a second pixel, and a light-emitting layer of the first color light-emitting element of another second pixel are integral with each other.

14. The display panel of claim 1 , wherein a width of each of the two first display regions in the first direction is greater than a width of the second display region.
