Abstract

The present inventive concept relates to a display device. A display device according to an exemplary embodiment of the present inventive concept include: a base layer including a plurality of islands in which a pixel is disposed, a plurality of bridges disposed around each of the plurality of islands, a plurality of first wires disposed in a bridge of the plurality of bridges connected to the pixel is disposed; an inorganic insulating layer disposed on the base layer and having an opening exposing a portion of the bridge; and an organic material layer covering the opening, wherein adjacent islands of the plurality of islands are connected to each other through at least the bridge of the plurality of bridges, and the plurality of first wires are disposed on the organic material layer.

Claims (53)

1. A display device comprising:

a base layer including islands and bridges connecting adjacent islands;

pixels disposed at the islands; and

at least one wire included in one of the bridges,

wherein at least one of the bridges is varied when the base layer is stretched, and

wherein a first portion of the wire in one of the bridges is disposed between a first protection layer and a second protection layer, and a second portion of the wire in one of the islands is disposed under a passivation layer.

2. The display device of claim 1 , wherein the at least one of the bridges is bent in a plan view when the base layer is stretched.

3. The display device of claim 2 , wherein a space between bridges adjacent to each other in a first direction among the bridges is widened, when the base layer is stretched in the first direction.

4. The display device of claim 1 , wherein a distance between the adjacent islands increases when the base layer is stretched.

5. The display device of claim 1 , wherein at least one of the islands rotates by a predetermined angle in a plan view when the base layer is stretched.

6. The display device of claim 1 , wherein at least one of the pixels corresponding to the at least one of the islands rotates by a predetermined angle in a plan view when the base layer is stretched.

7. The display device of claim 1 , wherein the islands comprises:

a first island;

a second island adjacent to the first island in a first direction;

a third island adjacent to the first island in a second direction intersecting the first direction; and

a fourth island adjacent to the second island in the second direction, and

wherein the first to fourth islands constitute a basic unit.

8. The display device of claim 7 , wherein each of the pixels comprises first to fourth pixels disposed on each of the first to fourth islands.

9. The display device of claim 7 , wherein the bridges comprise:

a first bridge connecting the first island and the second island;

a second bridge connecting the first island and the third island;

a third bridge connecting the second island and the fourth island, the third bridge being adjacent to the second bridge; and

a fourth bridge connecting the third island and the fourth island.

10. The display device of claim 9 , wherein the basic unit is repeatedly arranged in the first direction and the second direction, and

wherein, when the base layer is stretched in the first direction, the second bridge and the third bridge are bent so that a space between the second bridge and the third bridge is widened.

11. The display device of claim 9 , wherein:

the basic unit is repeatedly arranged in the first direction and the second direction, and

when the base layer is stretched in the second direction, a space between the fourth bridge of the basic unit and a first bridge of another basic unit adjacent to the basic unit in the second direction is widened.

12. The display device of claim 9 , wherein, when the base layer is stretched in the first direction, the first island rotates clockwise and the second island rotates counterclockwise.

13. The display device of claim 9 , wherein, when the base layer is stretched in the second direction, the first island rotates clockwise and the third island rotates counterclockwise.

14. The display device of claim 1 , wherein a first end of a first bridge of the bridges is directly connected to a first island of the islands and a second end of the first bridge is directly connected to a second island of the islands.

15. The display device of claim 1 , further comprising:

an inorganic insulating layer disposed on the base layer and having an open region exposing a portion of the bridges;

an organic material layer covering the open region;

a conductive pattern disposed on a bridge of the bridges and electrically connected to at least one of the pixels; and

an encapsulation layer disposed on the conductive pattern.

16. The display device of claim 1 , wherein

an island of the islands has a shape with four or more sides, and

a first side of the four or more sides is physically connected to a first bridge of the bridges.

17. The display device of claim 16 , wherein

the first bridge includes a curved portion disposed at a portion physically connected to the island, the curved portion having a curved side.

18. The display device of claim 17 , wherein

the first bridge further includes a straight portion physically connected to the curved portion, the straight portion having a straight line extending from the curved side.

19. The display device of claim 18 , wherein

the curved portion has first widths from the curved side to an opposite side of the first bridge facing the curved side,

the straight portion has second widths from the straight line to an opposite side of the first bridge facing the straight line, and

the first widths are greater than the second widths.

20. A display device comprising:

a base layer including islands and bridges connecting adjacent islands;

pixels disposed at the islands; and

at least one wire included in one of the bridges,

wherein at least one of the bridges is varied when the base layer is stretched, and

wherein a first portion of the wire in one of the bridges is disposed between a first protection layer and a second protection layer, and a second portion of the wire in one of the islands is disposed on an interlayer insulating layer.
