Abstract

A display device including a base substrate, a display element disposed on the base substrate, a thin film encapsulation layer covering the display element, a first organic layer disposed on the thin film encapsulation layer, an inorganic layer disposed on the first organic layer, touch electrodes disposed on the inorganic layer, and a second organic layer disposed on the inorganic layer, the second organic layer covering the touch electrodes.

Claims (48)

1. A display device comprising:

a base substrate;

a display element disposed on the base substrate;

a thin film encapsulation layer covering the display element;

a first organic layer disposed on the thin film encapsulation layer;

an inorganic layer disposed on the first organic layer;

touch electrodes disposed on the inorganic layer; and

a second organic layer disposed on the inorganic layer, the second organic layer covering the touch electrodes,

wherein the second organic layer is in contact with the inorganic layer.

2. The display device of claim 1 , further comprising a color filter disposed on the second organic layer.

3. The display device of claim 2 , wherein the color filter is disposed to overlap with an organic light emitting layer of the display element.

4. The display device of claim 1 , further comprising a black matrix disposed on the second organic layer.

5. The display device of claim 1 , wherein the base substrate has flexibility.

6. The display device of claim 1 , wherein the display element comprises:

a thin film transistor disposed on the base substrate;

an insulating layer disposed on the thin film transistor, the insulating layer comprising a contact hole through which a portion of a drain electrode of the thin film transistor; and

an organic light emitting element disposed on the insulating layer.

7. The display device of claim 6 , wherein the thin film transistor comprises:

a semiconductor layer disposed on the base substrate;

a gate electrode disposed on the semiconductor layer; and

source and drain electrodes each connected to the semiconductor layer.

8. The display device of claim 6 , wherein the organic light emitting element comprises:

a first electrode disposed on the insulating layer;

a pixel defining layer disposed on the insulating layer, the pixel defining layer defining pixel regions;

an organic light emitting layer disposed on the first electrode; and

a second electrode disposed on the organic light emitting layer.

9. The display device of claim 1 , wherein the first organic layer comprises multiple layers or a multi-layered structure.

10. A display device comprising:

a base substrate;

a display element disposed on the base substrate;

a thin film encapsulation layer covering the display element;

a first organic layer disposed on the thin film encapsulation layer;

an inorganic layer disposed on the first organic layer;

touch electrodes disposed on the inorganic layer; and

a second organic layer disposed on the inorganic layer, the second organic layer covering the touch electrodes,

wherein the second organic layer and the inorganic layer comprise a through-hole through which the first organic layer is exposed.

11. The display device of claim 10 , wherein the color filter is disposed on the first organic layer through the through-hole.

12. A method of manufacturing a display device, the method comprising:

forming a display element on a base substrate;

forming a thin film encapsulation layer covering the display element;

forming a first organic layer on the thin film encapsulation layer;

forming an inorganic layer on the first organic layer; and

forming a touch sensing part on the inorganic layer,

wherein the forming of the touch sensing part comprises:

forming touch electrodes on the inorganic layer;

forming a second organic layer on the inorganic layer to cover the touch electrodes;

forming a through-hole through which the second organic layer and the inorganic layer expose the first organic layer; and

forming a color filter on the second organic layer.
