Abstract

A display module includes a window member including a display area and a bezel area, a display panel including a display part corresponding to the display area, and an edge part corresponding to the bezel area and bent from the display part to extend away from the window member, and a protective frame accommodating the display panel and coupled to the window member.

First claim

What is claimed is:

1 . A display module comprising:
a window member comprising a display area and a bezel area; a display panel comprising a display part corresponding to the display area, and an edge part corresponding to the bezel area and bent from the display part to extend away from the window member; and a protective frame accommodating the display panel and coupled to the window member.

2 . The display module of claim 1 , wherein the edge part comprises:
a first edge part bent from a first side of the display part; and a second edge part opposite the first edge part and bent from a second side of the display part.

3 . The display module of claim 2 , further comprising a dummy member attached to the display panel and comprising a flat part corresponding to the display part, a first bending part corresponding to the first edge part, and a second bending part corresponding to the second edge part.

4 . The display module of claim 3 , wherein the display panel comprises:
a base layer; a circuit layer on the base layer; a display element layer on the circuit layer; and an encapsulation layer on the display element layer.

5 . The display module of claim 4 , wherein each of the first and second edge parts comprises a neutral plane, and
wherein the circuit layer at the first and second edge parts is applied with a compressive stress.

6 . The display module of claim 5 , wherein each of the first and second bending parts is applied with a tensile stress.

7 . The display module of claim 4 , wherein each of the first and second bending parts comprises a neutral plane, and
wherein the circuit layer of the first and second edge parts is applied with a compressive stress.

8 . The display module of claim 4 , wherein the circuit layer comprises a thin film transistor.

9 . The display module of claim 4 , wherein the display element layer comprises an organic light emitting diode.

10 . The display module of claim 1 , further comprising a touch panel between the display panel and the window member.

11 . The display module of claim 1 , further comprising a support member between the display panel and the protective frame.

12 . A display module comprising:
a first window member comprising a display area and a bezel area; a display panel comprising a display part corresponding to the display area, and an edge part corresponding to the bezel area and bent from the display part to extend away from the first window member; and a second window member facing the first window member such that the display panel is between the first and second window members.

13 . The display module of claim 12 , wherein the edge part comprises:
a first edge part bent from a first side of the display part; and a second edge part opposite the first edge part and bent from a second side of the display part.

14 . The display module of claim 13 , further comprising a dummy member attached to the display panel and comprising a flat part corresponding to the display part, a first bending part corresponding to the first edge part, and a second bending part corresponding to the second edge part.

15 . The display module of claim 14 , wherein the display panel comprises:
a base layer; a circuit layer on the base layer and comprising a thin film transistor; a display element layer on the circuit layer and comprising an organic light emitting diode; and an encapsulation layer on the display element layer.

16 . The display module of claim 15 , wherein each of the first and second edge parts comprises a neutral plane, and
wherein the circuit layer of the first and second edge parts is applied with a compressive stress.

17 . The display module of claim 15 , wherein each of the first and second bending parts comprises a neutral plane, and
wherein the circuit layer of the first and second edge parts is applied with a compressive stress.

18 . The display module of claim 15 , wherein the organic light emitting diode provides light to the first and second window members.

19 . The display module of claim 12 , further comprising a first touch panel between the display panel and the first window member.

20 . The display module of claim 12 , further comprising a second touch panel between the display panel and the second window member.
