Abstract

A display apparatus includes a substrate having an active area and a non-active area adjacent to the active area defined thereon; a first touch line in the non-active area and a second touch line on the first touch line; and a front member on the first and second touch lines, the front member being in at least a part of the non-active area, and including a transmissive part and a blocking part, wherein the first touch line is in an area overlapping the transmissive part, and the first touch lines includes at least two patterns.

Claims (42)

1 . A display apparatus, comprising:

a substrate including an active area and a non-active area adjacent to the active area;

a transistor disposed on the substrate;

a planarization layer disposed on the transistor;

an anode electrode disposed on the planarization layer;

an emission layer disposed on the anode electrode;

a cathode electrode disposed on the emission layer;

a protection layer disposed on the cathode layer, and having a first inclined surface overlapped the non-active area; and

a touch sensor layer disposed on the protection layer,

wherein the touch sensor layer comprises:

a touch buffer layer disposed on the protection layer;

a first touch line disposed on the touch buffer layer;

a touch insulating layer disposed on the first touch line;

a second touch line disposed on the touch insulating layer, and overlapped in the non-active area with the first touch line; and

a touch planarization layer disposed on the second touch line, and overlapped in the non-active area with some of the first touch line and some of the second touch line,

wherein each of the touch buffer layer, the first touch line, the touch insulating layer, and the second touch line include a second inclined surface disposed along the first inclined surface of the protection layer in the non-active area.

2 . The display apparatus according to claim 1 , wherein the inclined surface is disposed on at least three sides of the non-active area.

3 . The display apparatus according to claim 1 , wherein the inclined surface is disposed between a touch driver and the active area.

4 . The display apparatus according to claim 1 , wherein the first touch line and the second touch line overlapped each other on the first inclined surface of the protection layer.

5 . The display apparatus according to claim 1 , wherein the touch planarization layer overlapped at least some of the first touch line and at least some of the second touch line, on the first inclined surface.

6 . The display apparatus according to claim 1 , wherein a one end portion of the touch planarization is disposed on the second inclined surface of the second touch line, in the non-active area.

7 . The display apparatus according to claim 6 , wherein the one end of the touch planarization is formed a step on the second inclined surface.

8 . The display apparatus according to claim 1 , further comprising:

an adhesive layer disposed on the touch sensor layer, and covered the upper surface and side surface of the touch planarization layer in the non-active area.

9 . The display apparatus according to claim 1 , further comprising:

a polarizer disposed on the touch sensor layer.

10 . The display apparatus according to claim 9 , wherein the polarizer overlaps a one end portion of the touch planarization layer in the non-active area.

11 . The display apparatus according to claim 1 , further comprising:

a front member disposed on the touch sensor layer.

12 . The display apparatus according to claim 11 , wherein the front member comprises:

a transmissive part overlapped the active area and at least some of the non-active area; and

a blocking part overlapped the non-active area.

13 . The display apparatus according to claim 12 , wherein the blocking part overlaps a one end portion of the touch planarization layer.

14 . The display apparatus according to claim 12 , wherein the blocking part overlaps at least some of the first touch line and at least some of the second touch line.

15 . The display apparatus according to claim 14 , wherein the blocking part overlaps the second inclined surface of both of the first touch line and the second touch line.

16 . The display apparatus according to claim 12 , wherein the at least some of the first touch line overlaps the transmissive part.

17 . The display apparatus according to claim 16 , wherein a one end portion of the first touch line overlaps the transmissive part.

18 . The display apparatus according to claim 16 , wherein the first touch line comprises at least two patterns in the area overlapping the transmissive part.

19 . The display apparatus according to claim 18 , wherein each of the at least two patterns have a smaller width than the first touch line in the area overlapping the blocking part.

20 . The display apparatus according to claim 1 , wherein the touch sensor layer further comprises:

a touch connection electrode disposed on the touch buffer layer; and

a first touch electrode and a second touch electrode, disposed on the touch insulating layer, and connecting the touch connection electrode.
