Abstract

A display apparatus disposed on an object including a first surface having a first shape and a second surface having a second shape different from the first shape, the display apparatus includes a display panel arranged on the object, including a first display area extending along the first surface, a second display area extending along the second surface, a plurality of first pixels arranged with a preset interval in the first display area and a plurality of second pixels arranged with the preset interval in the second display area, where when tensile force is applied, a first elongation rate of the display panel in the first display area is different from a second elongation rate of the display panel in the second display area.

First claim

What is claimed is:

1 . A display apparatus disposed on an object comprising a first surface having a first shape and a second surface having a second shape different from the first shape, the display apparatus comprising:
a display panel arranged on the object and comprising:
a first display area extending along the first surface and comprising a plurality of first pixel areas and a plurality of first connection areas, a plurality of first pixels being respectively arranged in the plurality of first pixel areas, and the plurality of first connection areas extending between the plurality of first pixel areas adjacent to each other; and
a second display area extending along the second surface and comprising a plurality of second pixel areas and a plurality of second connection areas, a plurality of second pixels being respectively arranged in the plurality of second pixel areas, and the plurality of second connection areas extending between the plurality of second pixel areas adjacent to each other,
wherein the plurality of first pixels are arranged with a preset interval in the first display area, and the plurality of second pixels are arranged with the preset interval in the second display area.

2 . The display apparatus of claim 1 , wherein the plurality of first pixel areas are spaced apart from each other, and the plurality of first connection areas extend between the plurality of first pixel areas adjacent to each other, and
the plurality of second pixel areas are spaced apart from each other, and the plurality of second connection areas extend between the plurality of first pixel areas adjacent to each other.

3 . The display apparatus of claim 1 , wherein the plurality of first pixel areas ach extend to four first connection areas, and
the plurality of second pixel areas each extend to four second connection areas.

4 . The display apparatus of claim 3 , wherein four first connection areas connected to one of the plurality of first pixel areas extend in different directions, and
four second connection areas connected to one of the plurality of second pixel areas extend in different directions.

5 . The display apparatus of claim 3 , wherein four first connection areas connected to one of the plurality of first pixel areas and four second connection areas connected to one of the plurality of second pixel areas each extend in a curved shape.

6 . The display apparatus of claim 1 , wherein at least one of the plurality of first connection areas and at least one of the plurality of second connection areas each extend in a curved shape.

7 . The display apparatus of claim 1 , wherein at least one of the plurality of first connection areas and at least one of the plurality of second connection areas each comprise a curved portion.

8 . The display apparatus of claim 1 , wherein a first area of one of the plurality of first pixel areas is different from a second area of one of the plurality of second pixel area.

9 . The display apparatus of claim 1 , an area of the plurality of first pixels arranged in the one of the plurality of first pixel areas is same as an area of the plurality of second pixels arranged in the one of the plurality of second pixel area.

10 . The display apparatus of claim 1 , wherein a first width of one of the plurality of first connection areas is different from a second width of one of the plurality of second connection areas.

11 . The display apparatus of claim 1 , further comprising a film layer arranged at least one of a first surface of the display panel and a second surface of the display panel opposite to the first surface of the display panel in a thickness direction,
wherein the film layer comprises a polymer.

12 . The display apparatus of claim 11 , wherein a groove or hole is defined in the film layer.

13 . A display apparatus comprising:
a substrate comprising a first area and a second area, the first area having a first curvature, and the second area having a second curvature different from the first curvature; first pixels arranged on the first area of the substrate; second pixels arranged on the second area of the substrate; first pixel areas, in which the first pixels are respectively arranged, are spaced apart from each other; second pixel areas, in which the second pixels are respectively arranged, are spaced apart from each other; first connection areas connecting first pixel areas; and second connection areas connecting second pixel areas, wherein the first pixels are arranged with a preset interval in the first area, and the second pixels are arranged with the preset interval in the second area.

14 . The display apparatus of claim 13 , wherein at least one of the first connection areas and at least one of the second connection areas each comprise a curved portion.

15 . The display apparatus of claim 13 , wherein the first connection areas and the second connection areas each comprise a curved portion.

16 . The display apparatus of claim 13 , wherein at least one of the first pixel areas is connected to four first connection areas, and
at least one the plurality of second pixel areas is connected to four second connection areas.

17 . The display apparatus of claim 16 , wherein at least one of the first pixel areas is connected to four first connection areas comprising a curved portion, and
at least one the plurality of second pixel areas is connected to four second connection areas comprising a curved portion.

18 . The display apparatus of claim 13 , wherein the first pixel areas are each connected to four first connection areas, and
the second pixel areas are each connected to four second connection areas.

19 . The display apparatus of claim 18 , wherein the first pixel areas are each connected to four first connection areas comprising a curved portion, and
the second pixel areas are each connected to four second connection areas comprising a curved portion.

20 . The display apparatus of claim 13 , an area of the plurality of first pixels arranged in the one of the plurality of first pixel areas is same as an area of the plurality of second pixels arranged in the one of the plurality of second pixel area.
