Abstract

A display device includes a window including a front area and a corner area, and a display panel coupled to the window. The display panel includes a first area and a second area corresponding to the front area and the corner area, respectively. The second area includes a plurality of unit areas, a plurality of stretchable areas disposed between the plurality of unit areas, where a plurality of opening areas are defined through the display panel to be adjacent to the plurality of unit areas . A light emitting area of the second area has an area greater than an area of a corresponding light emitting area of the first area.

First claim

What is claimed is:

1 . A display device comprising:
a window comprising a front area, a first side area bent from a first side of the front area and having a first curvature, a second side area bent from a second side of the front area and having a second curvature, and a corner area disposed between the first side area and the second side area; and a display panel coupled to the window, wherein the display panel comprises: a first area corresponding to the front area, the first side area, and the second side area of the window, wherein first, second, and third light emitting areas are disposed in the first area; and a second area corresponding to the corner area of the window, wherein at least a partial area of the second area comprises:
a plurality of first unit areas, wherein the first, second, and third light emitting areas are disposed in each of the plurality of first unit areas; and
a plurality of stretchable areas disposed between the plurality of first unit areas,
wherein a plurality of opening areas are defined through the display panel to be adjacent to the plurality of first unit areas and the plurality of stretchable areas, and
wherein each of the first, second, and third light emitting areas of the second area has an area greater than an area of a corresponding light emitting area of the first, second, and third light emitting areas of the first area.

2 . The display device of claim 1 , wherein
the first area includes a plurality of second unit areas, the first, second, and third light emitting areas are disposed in each of the plurality of second unit areas, and the first, second, and third light emitting areas in each of the plurality of first unit areas have a same arrangement as the first, second, and third light emitting areas in each of the plurality of second unit areas.

3 . The display device of claim 1 , wherein
the plurality of first unit areas and the plurality of opening areas are alternately disposed in a first direction, and the plurality of first unit areas and the plurality of opening areas are alternately disposed in a second direction crossing the first direction.

4 . The display device of claim 1 , wherein
the plurality of first unit areas defines a plurality of stripe areas, each of the plurality of stripe areas comprises corresponding first unit areas of the plurality of first unit areas, each of the plurality of stripe areas expends along a first direction, and the plurality of stripe areas and the plurality of opening areas are alternately disposed in a second direction crossing the first direction.

5 . The display device of claim 1 , wherein the corner area has a plurality of curvatures.

6 . The display device of claim 5 , wherein a minimum curvature of the plurality of curvatures of the corner area is less than each of the first curvature and the second curvature.

7 . The display device of claim 1 , wherein each of the plurality of first unit areas further comprises a fourth light emitting area.

8 . The display device of claim 7 , wherein
the first area further comprises a fourth light emitting area, the first area includes a plurality of second unit areas, the first, second, third, and fourth light emitting areas are disposed in each of the plurality of second unit areas, and the first, second, third, and fourth light emitting areas in each of the plurality of first unit areas have a same arrangement as the first, second, third, and fourth light emitting areas in each of the plurality of second unit areas.

9 . The display device of claim 7 , wherein two light emitting areas of the first, second, third, and fourth light emitting areas of each of the plurality of first unit areas generate light having a same color as each other.

10 . The display device of claim 1 , wherein at least a portion of each of the stretchable areas has a curved line shape.

11 . The display device of claim 1 , wherein
the partial area of the second area is defined as an outside area, and the second area further comprises an inside area disposed adjacent to the outside area, wherein the inside area comprises: a plurality of third unit areas, wherein the first, second, and third light emitting areas are disposed in each of the plurality of third unit areas; and a plurality of fourth unit areas disposed adjacent to the plurality of third unit areas, wherein the first, second, and third light emitting areas are not disposed in each of the plurality of fourth unit areas, each of the fourth unit areas has an area corresponding to each of the third unit areas.

12 . A display device comprising:
a window comprising a front area, a first side area bent from a first side of the front area and having a first curvature, a second side area bent from a second side of the front area and having a second curvature, and a corner area disposed between the first side area and the second side area; and a display panel coupled to the window, wherein the display panel comprises: a first area corresponding to the front area, the first side area, and the second side area, wherein first, second, and third light emitting areas are disposed in the first area; and a second area corresponding to the corner area, wherein the first, second, and third light emitting areas are disposed in the second area, wherein a number of the first, second, and third light emitting areas per a unit area in the first area is greater than a number of the first, second, and third light emitting areas per the unit area in the second area, and each of the first, second, and third light emitting areas of the second area has an area greater than an area of a corresponding light emitting area of the first, second, and third light emitting areas of the first area.

13 . The display device of claim 12 , wherein a plurality of opening areas is defined through the display panel in the second area.

14 . The display device of claim 13 , wherein the second area comprises:
a plurality of first unit areas, wherein the first, second, and third light emitting areas are disposed in each of the plurality of first unit areas; and a plurality of stretchable areas disposed between the plurality of first unit areas and disposed adjacent to the plurality of opening areas.

15 . The display device of claim 13 , wherein
the second area comprises a plurality of first unit areas, wherein the first, second, and third light emitting areas are disposed in each of the plurality of first unit areas, the plurality of first unit areas defines a plurality of stripe areas, each of the plurality of stripe areas comprise corresponding first unit areas of the plurality of first unit areas, each of the plurality of stripe areas expends along a first direction, and the plurality of stripe areas and the plurality of opening areas are alternately disposed in a second direction crossing the first direction.

16 . A display panel comprising:
