Abstract

A display module includes a display part and a protection part disposed under the display part. The display part may include a display panel including a bending area bent about a bending axis extending in a direction, a first area disposed at a side of the bending area and displaying an image, and a second area disposed at another side of the bending area and overlapping the first area in a plan view; and a circuit board disposed on the display panel in the second area. The protection part may include a protective film including a top surface facing the second area and the circuit board and an opening overlapping the bending area in a plan view; and a cushion layer disposed on the top surface of the protective film.

Claims (78)

1 . A display module comprising:

a display part including:

a display panel including:

a bending area bent about a bending axis extending in a direction;

a first area disposed at a side of the bending area and displaying an image; and

a second area disposed at another side of the bending area and overlapping the first area in a plan view; and

a circuit board disposed on the display panel in the second area; and

a protection part disposed under the display part, the protection part including:

a protective film including:

a top surface facing the second area and the circuit board; and

an opening overlapping the bending area in a plan view; and

a cushion layer disposed directly on the top surface of the protective film, the cushion layer comprising a synthetic resin layer comprising a plurality of pores to protect the bending area of the display panel from external impact, wherein the display part further comprises:

a cover layer disposed on a rear surface of the display panel and including a first side surface adjacent to the bending area; and

a spacer disposed on a bottom surface of the cover layer and including a second side surface adjacent to the bending area, and

the second side surface is closer to the bending area than the first side surface.

2 . The display module of claim 1 , wherein the protective film includes a polyethylene terephthalate film.

3 . The display module of claim 1 , wherein the cushion layer covers the opening.

4 . The display module of claim 1 , wherein

an end of the cushion layer is disposed on the display panel in the second area, and

the protective film overlaps the end of the cushion layer and the circuit board in a plan view.

5 . The display module of claim 1 , wherein a thickness of the protective film is greater than a thickness of the cushion layer.

6 . The display module of claim 1 , wherein

the circuit board comprises:

a board; and

an electronic component disposed on the board, and

the electronic component is exposed from the cushion layer and the protective film.

7 . The display module of claim 1 , wherein

the display part further comprises:

a driving chip mounted on the display panel in the second area; and

a cover film covering the driving chip,

an end of the cover film is aligned with a boundary between the bending area and the second area.

8 . The display module of claim 1 , wherein

the opening penetrates the protective film,

the cushion layer comprises foam, and

the cushion layer covers an entirety of the opening in a plan view.

9 . The display module of claim 1 , wherein a modulus of the spacer is less than a modulus of the cover layer.

10 . The display module of claim 1 , wherein the display part further comprises:

a first film disposed between the first area of the display panel and the cover layer; and

a second film disposed between the second area of the display panel and the spacer and spaced apart from the first film.

11 . The display module of claim 10 , wherein the first film and the second film include a same material.

12 . The display module of claim 10 , wherein

the first film includes a third side surface adjacent to the bending area, and

the third side surface is closer to the bending area than the first side surface.

13 . A display module comprising:

a display part including:

a display panel having a front surface opposite a rear surface, the display panel including:

a first area including a display area, wherein an image is displayed on the front surface of the display panel in the first area;

a bending area extending from a side of the first area; and

a second area extending from a side of the bending area;

a cover layer disposed on a rear surface of the display panel;

a spacer disposed on a bottom surface of the cover layer;

a circuit board disposed on the second area; and

a cover film disposed on the front surface of the second area of the display panel and directly on the circuit board; and

a protection part disposed under the display part, wherein;

an end of the cover film is aligned with a boundary between the bending area and the second area, and

the cover film and the circuit board are disposed on a same side of the second area of the display panel.

14 . The display module of claim 13 , wherein the cover layer includes a first side surface adjacent to the bending area; and

the spacer includes a second side surface adjacent to the bending area and protruding from the first side surface of the cover layer toward the bending area.

15 . The display module of claim 13 , wherein a modulus of the spacer is less than a modulus of the cover layer.

16 . The display module of claim 14 , wherein

the display part further comprises:

a first film overlapping the first area in a plan view and disposed between the display panel and the cover layer; and

a second film overlapping the second area in a plan view and spaced apart from the first film,

the bending area is disposed between the first film and the second film, and

the first film and the second film are disposed on a same side of the display panel.

17 . The display module of claim 16 , wherein

the first film includes a third side surface adjacent to the bending area, and

the third side surface protrudes from the first side surface toward the bending area.

18 . The display module of claim 13 , wherein the display part further comprises:

a window disposed on the display panel;

an anti-reflection layer disposed between the window and the display panel, and

the anti-reflection layer is disposed between the window and the first film in a thickness direction of the display panel.

19 . The display module of claim 13 , wherein

the bending area is bent about a bending axis extending in a direction, and

the second area and the circuit board are located between the first area and the protection part in a cross-sectional view.

20 . The display module of claim 13 , wherein the protection part comprises:

a cushion layer; and

a protective film disposed on a rear surface of the cushion layer and exposing a portion of the rear surface of the cushion layer the portion of the rear surface of the cushion layer overlapping the bending area in a plan view.
