Abstract

A display device includes a substrate including an active area and a non-active area which is disposed at an outer periphery of the active area, the non-active area including a pad unit in which a plurality of pad electrodes are disposed and a non-pad unit excluding the pad unit, an insulating layer on the substrate, a pixel unit on the insulating layer, an encapsulation unit on the pixel unit, a film member below the substrate and protruding outwardly from the substrate, an organic pattern at an edge of the film member protruding outwardly from the substrate, an anisotropic conductive film on the pad electrodes, a side surface of the insulating layer, and a side surface of the substrate and a flexible film that is on the plurality of pad electrodes to be electrically connected to the pad electrodes by the anisotropic conductive film.

Claims (41)

1 . A display device, comprising:

a substrate including an active area in which a plurality of pixels is defined, and a non-active area which is disposed at an outer periphery of the active area, wherein the non-active area includes a pad unit in which a plurality of pad electrodes are disposed and a non-pad unit excluding the pad unit;

an insulating layer on the substrate;

a pixel unit on the insulating layer;

an encapsulation unit on the pixel unit;

a film member which is disposed below the substrate and protrudes outwardly from the substrate;

an organic pattern which is disposed at an edge of the film member protruding outwardly from the substrate;

an anisotropic conductive film which is disposed on the plurality of pad electrodes, a side surface of the insulating layer, and a side surface of the substrate; and

a flexible film which is disposed on the plurality of pad electrodes to be electrically connected to the plurality of pad electrodes by means of the anisotropic conductive film,

wherein the organic pattern is in contact with the anisotropic conductive film in an area corresponding to the pad unit, and

wherein the organic pattern is disposed to enclose the substrate.

2 . The display device according to claim 1 , further comprising:

a seal member disposed in the non-active area,

wherein the seal member is in contact with the organic pattern in an area corresponding to the non-pad unit.

3 . The display device according to claim 2 , wherein the anisotropic conductive film is in contact with a side surface of the insulating layer and an upper surface of the organic pattern and the upper surface of the organic pattern is disposed to be lower than the upper surface of the substrate.

4 . The display device according to claim 2 , wherein the organic pattern is disposed so as to enclose the insulating layer and the substrate and the anisotropic conductive film is disposed so as to enclose a part of the organic pattern.

5 . The display device according to claim 4 , wherein the organic pattern is in contact with the side surface of the insulating layer and the side surface of the substrate and the anisotropic conductive film is in contact with a part of the side surface of the organic pattern.

6 . The display device according to claim 4 , wherein the seal member is disposed so as to enclose the other part of the organic pattern.

7 . The display device according to claim 6 , wherein the seal member is in contact with the other part of the side surface of the organic pattern.

8 . The display device according to claim 1 , wherein the substrate is formed of one of a conductive oxide layer and an oxide semiconductor.

9 . The display device according to claim 8 , further comprising:

a lower planarization seal disposed between the substrate and the film member.

10 . The display device according to claim 9 , wherein the organic pattern is disposed above the lower planarization seal.

11 . The display device according to claim 8 , further comprising:

a protection film disposed above the encapsulation unit so as to overlap the entire substrate.

12 . The display device according to claim 1 , wherein the organic pattern is formed of a material which is capable of being decomposed by laser.

13 . The display device according to claim 12 , wherein

the organic pattern includes at least one from a group consisting of xylene, toluene, ethyl acetate, terpene, and turpentine.

14 . The display device according to claim 12 , wherein the organic pattern includes a pigment.

15 . The display device according to claim 1 , wherein the film member includes at least one of a polarizing plate and a barrier film.

16 . A display device, comprising:

a substrate including an active area in which a plurality of pixels is defined and a non-active area which is disposed at an outer periphery of the active area, wherein the non-active area includes a pad unit in which a plurality of pad electrodes are disposed and a non-pad unit excluding the pad unit;

a pixel unit on the substrate;

an encapsulation unit on the pixel unit;

a seal member disposed in the non-active area and disposed to enclose side surfaces of the pixel unit and the encapsulation unit;

a film member which is disposed below the substrate and protrudes outwardly from the substrate;

an organic pattern which is disposed at an edge of the film member protruding outwardly from the substrate;

an anisotropic conductive film which is disposed on the plurality of pad electrodes and a side surface of the substrate; and

a flexible film which is disposed on the plurality of pad electrodes to be electrically connected to the plurality of pad electrodes by means of the anisotropic conductive film,

wherein the organic pattern is in contact with the anisotropic conductive film in an area corresponding to the pad unit, and

wherein the organic pattern is disposed to enclose the substrate.
