Abstract

The present application describes a display panel and a display device. The display panel according to the present application includes: an array substrate; and a plurality of pixels, the pixels including light-emitting elements; wherein the light-emitting element is located at a side of the array substrate and includes a light-emitting region and a non-light-emitting region; and wherein at least two of the light-emitting elements are arranged in different manners.

Claims (35)

1 . A display panel, comprising:

an array substrate; and

a plurality of pixels, one of the plurality of pixels comprising a light-emitting element;

wherein the light-emitting element is located at a side of the array substrate and comprises a light-emitting region and a non-light-emitting region; and

wherein at least two of the light-emitting elements are arranged in such different manners that an arrangement direction in which the light-emitting region is arranged with respect to the non-light-emitting region in one of the at least two light-emitting elements is different from an arrangement direction in which the light-emitting region is arranged with respect to the non-light-emitting region in another of the at least two light-emitting elements.

2 . The display panel according to claim 1 , wherein the display panel further comprises a color conversion layer, which is located at a side of the light-emitting element away from the array substrate.

3 . The display panel according to claim 2 , wherein the light-emitting elements are light-emitting elements for emitting light of first color, and the color conversion layer corresponding to one pixel of the plurality of pixel is configured to convert the light of first color into light of a color corresponding to the pixel.

4 . The display panel according to claim 1 , wherein a space between two light-emitting elements of the at least two light-emitting elements in a first direction is larger or smaller than a space between the light-emitting regions of the two light-emitting elements in the first direction.

5 . The display panel according to claim 1 , wherein the light-emitting elements include a first light-emitting element and a second light-emitting element;

a distance from the light-emitting region of the first light-emitting element to the second light-emitting element is D 1 ; and

a distance from the non-light-emitting region of the first light-emitting element to the second light-emitting element is D 2 ;

where D 1 >D 2 .

6 . The display panel according to claim 1 , wherein the display panel further includes a light-shielding part which is located between the light-emitting element and the array substrate,

the light-emitting elements include a first light-emitting element and a second light-emitting element;

the light-shielding part is located at a side of the light-emitting region of the first light-emitting element close to the second light-emitting element.

7 . The display panel according to claim 1 , wherein the light-emitting elements include a first light-emitting element and a second light-emitting element, and

the light-shielding part includes a first light-shielding part and a second light-shielding part, and in the light-shielding part corresponding to the first light-emitting element, the first light-shielding part is located at a side of the second light-shielding part close to the second light-emitting element, and the first light-shielding part has a size larger than that of the second light-shielding part.

8 . The display panel according to claim 1 , wherein the light-emitting elements include a first light-emitting element and a second light-emitting element, a color of the first light-emitting element is different from a color of a first pixel of the plurality of pixels corresponding the first light-emitting element, and a color of the second light-emitting element is the same as a color of a second pixel of the plurality of pixels corresponding the second light-emitting element.

9 . The display panel according to claim 1 , wherein the first light-emitting element and the second light-emitting element are arranged along a first direction, the barrier walls include a first barrier wall located between the first light-emitting element and the second light-emitting element, and the first barrier wall extends along a second direction,

along the first direction: a distance from the light-emitting region of the first light-emitting element to the light-shielding part is L 1 , and a distance from the light-emitting region of the first light-emitting element to the first barrier wall is L 2 , and

along the second direction: a distance from the light-emitting region of the first light-emitting element to one of ends the light-shielding part in the second direction is H 1 , and a distance from the light-emitting region of the first light-emitting element to one of ends of the first barrier wall in the second direction is H 2 ,

where H 1 > (L 1 *H 2 )/L 2 .

10 . The display panel according to claim 1 , wherein the light-emitting elements comprise a first light-emitting element, a third light-emitting element, and a second light-emitting element located between the first light-emitting element and the third light-emitting element;

a distance from the light-emitting region of the second light-emitting element to the third light-emitting element is smaller than a distance from the light-emitting region of the second light-emitting element to the first light-emitting element;

a wavelength of light of a first pixel of the plurality of pixels corresponding to the first light-emitting element is between a wavelength of light of a second pixel of the plurality of pixels corresponding to the second light-emitting element and a wavelength of light of a third pixel of the plurality of pixels corresponding to the third light-emitting element.

11 . The display panel according to claim 1 , wherein the display panel further includes an opposite substrate which is provided opposite to the array substrate, and includes a plurality of barriers walls;

wherein the barrier walls are located at a side of the opposite substrate facing the array substrate, and disposed corresponding to respective intervals among the light-emitting elements.

12 . The display panel according to claim 1 , wherein the display panel further includes a color filter layer,

wherein the color filter layer is disposed corresponding to the light-emitting elements.

13 . A display device, comprising a display panel,

wherein the display panel comprises an array substrate and a plurality of pixels, one of the plurality of pixels comprising a light-emitting element;

the light-emitting element is located at a side of the array substrate and comprises a light-emitting region and a non-light-emitting region; and
