Abstract

The present disclosure relates to a display panel including a display area that can be stretched by including a plurality of stretching units and a peripheral area positioned at an edge of the display area. Each of the stretching units includes: a plurality of islands separately disposed to include a plurality of pixels disposed therein; a plurality of bridges extended from the islands to connect adjacent islands or to connect the islands with the peripheral area; and a plurality of openings disposed adjacent to the bridges, between the bridges, and between the bridges and the islands, wherein areas of the islands are gradually increased toward the peripheral area.

First claim

What is claimed is:

1. A display panel comprising:
a display area which can be stretched by including a plurality of stretching units; and
a peripheral area at an edge of the display area,
wherein each of the stretching units includes:
a plurality of islands separately disposed to include a plurality of pixels disposed therein;
a plurality of bridges extended from the islands to connect adjacent islands or to connect the islands with the peripheral area; and
a plurality of openings disposed adjacent to the bridges, between the bridges, and between the bridges and the islands,
wherein areas of the islands are gradually increased toward the peripheral area.

2. The display panel of claim 1 , wherein widths of the bridges are gradually increased toward the peripheral area.

3. The display panel of claim 1 , wherein areas of the openings are gradually reduced toward the peripheral area.

4. The display panel of claim 1 , wherein areas of the islands are gradually increased toward the peripheral area, throughout the stretching units from the peripheral area to an area which corresponds from one of the stretching units to 1% of a length of the display panel.

5. The display panel of claim 1 , wherein the display panel includes:
a substrate configured to include the display area and the peripheral area; and
a plurality of insulating layers stacked on the substrate,
wherein the openings are in areas through which the insulating layers and the substrate are extended.

6. A display panel comprising
a display area which can be stretched by including a plurality of stretching units; and
a peripheral area positioned at an edge of the display area,
wherein each of the stretching units includes:
a plurality of islands separately disposed to include a plurality of pixels disposed therein;
a plurality of bridges extended from the islands to connect adjacent islands or to connect the islands with the peripheral area; and
a plurality of openings disposed adjacent to the bridges, between the bridges, and between the bridges and the islands,
wherein widths of the bridges that connect the islands with the edge are wider than those of the bridges that connect the islands.

7. The display panel of claim 6 , wherein an area of the island that is most adjacent to the edge is wider than that of the island that is surrounded by the islands adjacent thereto.

8. The display panel of claim 6 , wherein an area of the opening that is most adjacent to the edge is narrower than that of another of the openings.

9. The display panel of claim 6 , wherein areas of the islands are gradually increased toward the edge, throughout the stretching units from the peripheral area to an area which corresponds from one of the stretching units to 1% of a length of the display panel.

10. The display panel of claim 6 , wherein the display panel includes a substrate and a plurality of insulating layers stacked on the substrate, and
the openings are in areas through which the insulating layers and the substrate are extended.

11. A display panel comprising:
an insulating layer, which comprises a first edge, a second edge, and a set of openings, wherein the set of openings is positioned between the first edge and the second edge and includes a first opening and a second opening, wherein a minimum distance between the first opening and the first edge is less than a minimum distance between the second opening and the first edge and is less than a minimum distance between the second opening and the second edge, wherein the first opening is narrower than the second opening in a direction parallel to the first edge, wherein the first opening is narrower than the second opening in a direction perpendicular to the first edge, and wherein the first opening is smaller than the second opening; and
a first pixel, which comprises a first transistor, wherein the first transistor is positioned between the first opening and the second opening.

12. The display panel of claim 11 , wherein the insulating layer comprises a third opening and a fourth opening, wherein the third opening immediately neighbors the first opening with no intervening opening, wherein the fourth opening immediately neighbors the second opening without any intervening opening, and wherein a minimum distance between the first opening and the third opening is greater than a minimum distance between the second opening and the fourth opening.

13. The display panel of claim 11 , wherein the insulating layer comprises a third edge and a fourth edge, wherein the set of openings is positioned between the third edge and the fourth edge and includes a third opening, wherein a minimum distance between the third opening and the third edge is less than a minimum distance between the second opening and the third edge and is less than a minimum distance between the second opening and the fourth edge, and wherein the third opening is smaller than the second opening.

14. The display panel of claim 13 , wherein the set of openings includes a fourth opening, wherein the fourth opening is positioned between the first opening the third edge, is positioned between the third opening and the first edge, and is smaller than the second opening.

15. The display panel of claim 14 , wherein the fourth opening extends perpendicular to the first opening.

16. The display panel of claim 11 , wherein the set of openings includes a third opening, wherein the third opening is positioned between the second opening and the second edge and is larger than the second opening.

17. The display panel of claim 11 , wherein the first opening immediately neighbors the first edge with no intervening opening, wherein the set of openings includes a third opening, wherein the third opening immediately neighbors the second opening without any intervening opening, wherein a minimum distance between the first opening and the first edge is greater than a minimum distance between the second opening and the third opening.

18. The display panel of claim 11 , wherein the set of openings includes a third opening, wherein the third opening is positioned between the first opening and the second opening, immediately neighbors each of the first opening and the second opening with no intervening openings, is larger than the first opening, and is smaller than the second opening.

19. The display panel of claim 11 , wherein the insulating layer comprises a third edge and a fourth edge, wherein the set of openings is positioned between the third edge and the fourth edge, wherein a minimum distance between the first opening and the third edge is greater than a minimum distance between the second opening and the third edge, and wherein a minimum distance between the first opening and the fourth edge is greater than a minimum distance between the second opening and the fourth edge.

20. The display panel of claim 11 , wherein the set of openings includes a first plurality of openings and a second plurality of openings, wherein the first plurality of openings includes the first opening and is positioned between the second plurality of openings and the first edge, wherein the second plurality of openings includes the second opening, and wherein each opening of the second plurality of openings is larger than each opening of the first plurality of openings.

21. The display panel of claim 11 , wherein the set of openings includes a first plurality of openings and a second plurality of openings, wherein the first plurality of openings includes the first opening an
