Abstract

A display device includes: a display panel which displays an image; and a frame set disposed on a rear side of the display panel, where the frame set bends the display panel. The frame set includes a frame including a body extending in a longitudinal direction and a head protruding toward the rear side of the display panel from the body, and a wire fixed to the head and extending in a longitudinal direction of the frame.

First claim

What is claimed is:

1. A display device comprising:
a display panel;
a frame set which bends the display panel;
wherein the frame set comprises
a frame including a body and a head protruding toward the display panel from the body,
an intermediate frame facing the frame and disposed between the frame and the display panel, and
a wire extending within the interior of the frame,
wherein the intermediate frame is spaced apart from the body of the frame and connected to the head of the frame,
wherein the wire is in a linear straight shape when the display panel is in an unbent state, and
wherein the wire is in a curved shape when the display panel is in a bent state.

2. The display device of claim 1 , wherein
the frame further includes a protrusion pattern protruding toward the display panel from the body, the protrusion pattern is apart from the head,
a through hole is defined through the protrusion pattern, and the wire extends through the through hole.

3. The display device of claim 1 , wherein
the intermediate frame moves relative to the head.

4. The display device of claim 3 , wherein
one of the head and the intermediate frame comprises a concave portion facing the other one of the head and the intermediate frame, and
the other one of the head and the intermediate frame comprises a convex portion facing the concave portion.

5. The display device of claim 1 ,
wherein the display panel includes a structure and/or material that is stretchable and/or contractible in at least a portion.

6. The display device of claim 5 ,
the display panel comprises
pixel areas spaced apart from one another, and
connection areas connecting the pixel areas.

7. The display device of claim 6 ,
wherein connection areas include a plurality of connection areas extending in different direction from one of pixel areas, each of the plurality of connection areas is connected to another pixel area adjacent to the one pixel area.

8. The display device of claim 7 ,
wherein the display panel further comprises through-portions surrounded and defined by the plurality of connection areas and the pixel areas.

9. The display device of claim 8 ,
wherein the display panel comprises a substrate, a pixel circuit layer, a display element layer, and an encapsulation layer, the substrate, the pixel circuit layer, the display element layer, and the encapsulation layer are separated with the through-portion therebetween.

10. The display device of claim 9 ,
wherein the display panel comprises a first pixel area and a second pixel area separated with the through-portion therebetween,
the first pixel area and the second pixel area comprise a first dam portion and a second dam portion, respectively, disposed adjacent to the through-portion.
