Claims (50)

1 . A display device comprising:

a display module, the display module comprising:

a cover spacer,

a display panel comprising a first portion and a second portion located on opposite sides of the cover spacer, the first portion including a display area, and

a step compensation portion disposed on the second portion of the display panel and an edge portion of the cover spacer; and

an outer structure surrounding an outer part of the display module, wherein

an edge portion of the second portion of the display panel extends inward from the outer part of the display module and protrudes beyond the edge portion of the cover spacer,

a recessed portion is disposed at the edge portion of the cover spacer and under the edge portion of the second portion of the display panel, and

the step compensation portion overlaps the recessed portion.

2 . The display device of claim 1 , wherein the step compensation portion is disposed at an inner side of the outer structure.

3 . The display device of claim 1 , wherein the step compensation portion is spaced apart from the outer structure.

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

a cover window, disposed on

the first portion of the display panel, wherein

the step compensation portion overlaps the edge portion of the second portion.

5 . The display device of claim 1 , wherein the step compensation portion is filled in the recessed portion.

6 . The display device of claim 5 , wherein the step compensation portion is in contact with at least one of a bottom surface, a side surface, or a top surface of a first end portion of the display panel disposed at the edge portion of the second portion of the display panel.

7 . The display device of claim 1 , wherein the step compensation portion is in contact with a side surface of the edge portion of the cover spacer defining an end of the recessed portion.

8 . The display device of claim 1 , wherein

the display panel comprises a through hole at the edge portion of the second portion of the display panel penetrating entirely through the display panel and exposing at least a portion of the recessed portion.

9 . The display device of claim 8 , wherein the through hole is disposed at the edge portion of the second portion of the display panel and has a combed shape or a saw-toothed shape.

10 . The display device of claim 8 , wherein the through hole is spaced apart from the edge portion of the second portion of the display device and is disposed at a first end portion of the display panel.

11 . The display device of claim 10 , wherein the first end portion of the display device has a ladder shape that extends inward, away from the outer structure.

12 . The display device of claim 8 , wherein the through hole comprises a plurality of holes spaced apart from each other and disposed adjacent to the edge portion of the display panel to extend inward, away from the outer structure.

13 . The display device of claim 8 , wherein the through hole comprises a single hole extending inward, away from the outer structure and adjacent to the edge portion of the display panel.

14 . A display device comprising:

a display panel comprising a main region, a bending area disposed on a side of the main region and bent to a bottom side of the main region, and a sub-region disposed on a side of the bending area and at the bottom side of the main region, and comprising a first portion disposed in the main region and a second portion disposed in the sub-region;

a cover spacer disposed between the first portion and the second portion;

a step compensation portion disposed on the second portion of the display panel; and

an outer structure disposed to surround the display panel, the cover spacer, and the step compensation portion, wherein

an edge portion of the second portion extending inward, away from the outer structure and protruding beyond an edge portion of the cover spacer, forming a recessed portion disposed between the first portion and the edge portion of the second portion and at the edge portion of the cover spacer, and

the step compensation portion overlaps the recessed portion.

15 . The display device of claim 14 , wherein the step compensation portion is disposed in the recessed portion and below at least a portion of the first portion.

16 . The display device of claim 15 , wherein the outer structure comprises:

an outer portion disposed at an outer side of the bending area, and

an inner portion disposed at an inner side of the bending area.

17 . The display device of claim 16 , further comprising a bending protection layer disposed at an outer side of the display panel in the bending area,

wherein the outer portion is in contact with the bending protection layer.

18 . The display device of claim 14 , wherein the display panel comprises a through hole edge portion of the second portion penetrating entirely through the display panel and exposing at least a portion of the recessed portion.

19 . A display module comprising:

a cover panel;

a cover spacer disposed on the cover panel;

a display panel comprising a first portion and a second portion located on opposite sides of the cover panel, the first portion including a display area; and

a step compensation portion disposed on the cover panel, the second portion of the display panel, and an edge portion of the cover spacer, wherein

an edge portion of the second portion of the display panel extends inward from an outer part of the display module and protrudes beyond the edge portion of the cover spacer,

a recessed portion is disposed at the edge portion of the cover spacer and between the cover panel and the edge portion of the second portion of the display panel, and

the step compensation portion overlaps the recessed portion.

20 . The display module of claim 19 , further comprising:
