Abstract

Disclosed are display panels and display devices. The display panel comprises a base layer which includes a first region and a second region having a first sub-region and a second sub-region, first pixels in the first region, and second pixels in the first sub-region. Each of the first and second pixels includes a pixel electrode, an emission layer on the pixel electrode, and a common electrode on the emission layer. The pixel electrode is shifted relative to the emission layer in a direction away from the second sub-region.

Claims (55)

1. A display panel, comprising:

a base layer that includes a first region and a second region, the second region including a first sub-region and a second sub-region, wherein the second sub-region corresponds to a transmission region;

a plurality of first pixels on the first region; and

a plurality of second pixels on the first sub-region, wherein

each of the plurality of first pixels includes a first pixel electrode, a first emission layer on the first pixel electrode, and a first common electrode on the first emission layer,

each of the plurality of second pixels includes a second pixel electrode, a second emission layer on the second pixel electrode, and a second common electrode on the second emission layer, and

the second pixel electrode is shifted relative to the second emission layer in a direction away from the second sub-region such that the second pixel electrode does not overlap an edge of the second emission layer closest among all edges of the second emission layer to the second sub-region.

2. The display panel of claim 1 , wherein

each of the first and second sub-regions is provided in plural,

the plurality of first sub-regions and the plurality of second sub-regions are defined alternately in a first direction, and

the plurality of first sub-regions and the plurality of second sub-regions are defined alternately in a second direction intersecting the first direction.

3. The display panel of claim 1 , wherein

the first sub-region and the second sub-region are adjacent to each other in a first direction, and

when viewed on a plane, a center of an overlapping region where the second emission layer overlaps the second pixel electrode is spaced apart in the first direction from a center of the second emission layer.

4. The display panel of claim 3 , wherein, when viewed on a plane, a center of an overlapping region where the first emission layer overlaps the first pixel electrode is spaced apart from a center of the first emission layer in a direction opposite to the first direction.

5. The display panel of claim 1 , wherein each of the first emission layer, the first pixel electrode, the second emission layer, and the second pixel electrode has a quadrangular shape when viewed on a plane.

6. The display panel of claim 1 , wherein

when viewed on a plane, an area of the first emission layer is greater than an area of the first pixel electrode, and

when viewed on a plane, an area of the second emission layer is greater than an area of the second pixel electrode.

7. The display panel of claim 1 , wherein

the first sub-region and the second sub-region are adjacent to each other in a first direction,

a first overlapping region is defined where the first pixel electrode overlaps the first emission layer,

a second overlapping region is defined where the second pixel electrode overlaps the second emission layer,

the first overlapping region is spaced apart from the second overlapping region in a second direction intersecting the first direction, and

an imaginary line dose not overlap a center of the first overlapping region, the imaginary line penetrating a center of the second overlapping region and extending in the second direction.

8. The display panel of claim 1 , wherein no pixel is disposed on the second sub-region.

9. The display panel of claim 1 , wherein

the first emission layer is provided in plural,

the second emission layer is provided in plural, and

the plurality of first emission layers and the plurality of second emission layers are arranged in the same way.

10. The display panel of claim 1 , wherein

the first pixel electrode is provided in plural,

the second pixel electrode is provided in plural,

the plurality of first pixel electrodes are arranged in a first way, and

the plurality of second pixel electrodes are arranged in a second way different from the first way.

11. The display panel of claim 1 , wherein

the first sub-region and the second sub-region are adjacent to each other in a first direction,

each of the first and second pixels includes a plurality of first pixel emission regions, a plurality of second pixel emission regions, and a plurality of third pixel emission regions,

the first pixel emission regions and the second pixel emission regions are alternately arranged along a second direction intersecting the first direction,

the second pixel emission regions and the third pixel emission regions are alternately arranged along the second direction,

the second pixel emission regions are spaced apart in the first direction from the third pixel emission regions, and

the first pixel emission regions are spaced apart in the first direction from the second pixel emission regions.

12. The display panel of claim 11 , wherein

the number of the first pixel emission regions on the first sub-region is two,

the number of the second pixel emission regions on the first sub-region is four,

the number of the third pixel emission regions on the first sub-region is two,

the first pixel emission regions are light emitting regions of a red pixel,

the second pixel emission regions are light emitting regions of a green pixel, and

the third pixel emission regions are light emitting regions of a blue pixel.

13. The display panel of claim 1 , wherein

the first sub-region and the second sub-region are adjacent to each other in a first direction,

the first pixel electrode is provided in plural,

the second pixel electrode is provided in plural, and

a first minimum distance between the plurality of first pixel electrodes that are spaced apart in the first direction is greater than a second minimum distance between the plurality of second pixel electrodes that are spaced apart in the first direction.

14. The display panel of claim 1 , wherein a size of the first pixel electrode is greater than a size of the second pixel electrode.
