Abstract

A display device includes a display layer including a light-emitting element and a pixel-defining layer, a touch sensing layer disposed on the display layer and including a touch insulating layer and a reflective pattern, and a light-blocking pattern disposed on the touch sensing layer and including a first pattern overlapping the pixel-defining layer and a second pattern overlapping the reflective pattern, where the reflective pattern and the second pattern each have a vertical length and a horizontal length different from each other in a plan view.

Claims (58)

1 . A display device comprising:

a display layer comprising a light-emitting element and a pixel-defining layer;

a touch sensing layer disposed on the display layer and comprising a touch insulating layer and a reflective pattern; and

a light-blocking pattern disposed on the touch sensing layer and comprising a first pattern overlapping the pixel-defining layer and a second pattern overlapping the reflective pattern,

wherein the reflective pattern and the second pattern each overlap the light-emitting element in a plan view,

wherein the reflective pattern and the second pattern each have a vertical length and a horizontal length different from each other in the plan view, and

wherein the pixel-defining layer defines an emission area and a non-emission area, a planar shape of the emission area is circular, elliptical, or polygonal having four or more sides, and a planar shape of each of the reflective pattern and the second pattern is elliptical or polygonal having four or more sides.

2 . The display device of claim 1 , wherein

the reflective pattern and the second pattern overlap the emission area.

3 . The display device of claim 2 , wherein the first pattern does not overlap the emission area, and the first pattern overlaps the non-emission area.

4 . The display device of claim 1 , wherein

the touch sensing layer comprises a driving electrode disposed on the touch insulating layer, and

the driving electrode and the reflective pattern are disposed in a same layer as each other.

5 . The display device of claim 1 , wherein

the touch sensing layer comprises a driving electrode, a sensing electrode and a bridge electrode, and

the reflective pattern is spaced apart from the driving electrode, the sensing electrode and the bridge electrode in the plan view.

6 . The display device of claim 1 , wherein an area of the reflective pattern is equal to an area of the second pattern.

7 . The display device of claim 1 , wherein a shape of the reflective pattern is identical to a shape of the second pattern in the plan view.

8 . The display device of claim 1 , wherein the vertical length is greater than the horizontal length in the plan view.

9 . The display device of claim 1 , wherein a width of the reflective pattern in a direction is less than a width of the second pattern in the direction.

10 . The display device of claim 1 , wherein an area of the reflective pattern is less than an area of the second pattern.

11 . The display device of claim 1 , wherein

the touch insulating layer comprises a trench formed in an upper surface, and

the reflective pattern is disposed on the trench.

12 . The display device of claim 1 , wherein

the display layer comprises a thin-film encapsulation layer disposed between the light-emitting element and the touch sensing layer,

the touch sensing layer comprises a bridge electrode disposed between the thin-film encapsulation layer and the touch insulating layer, and

the bridge electrode and the reflective pattern are disposed in a same layer as each other.

13 . The display device of claim 1 , wherein the second pattern is spaced apart from the first pattern and is surrounded by the first pattern in the plan view.

14 . The display device of claim 1 , wherein

the light-emitting element comprises a pixel electrode,

the pixel-defining layer is provided with an opening exposing the pixel electrode, and

the reflective pattern is disposed in a central area of the opening of the pixel-defining layer in the plan view.

15 . The display device of claim 1 , wherein the vertical length of the reflective pattern is less than or equal to a distance between opposing sides of the pixel-defining layer, which are opposite to each other in an extension direction of the vertical length.

16 . A display device comprising:

a display layer comprising an emission area and a non-emission area;

a touch sensing layer disposed on the display layer and comprising a driving electrode overlapping the non-emission area and a reflective pattern overlapping the emission area in a plan view; and

a light-blocking pattern disposed on the touch sensing layer and comprising a first pattern overlapping the non-emission area and a second pattern overlapping the emission area in the plan view,

wherein the reflective pattern and the second pattern each have a vertical length greater than a horizontal length in the plan view, and

wherein the pixel-defining layer defines an emission area and a non-emission area, a planar shape of the emission area is circular, elliptical, or polygonal having four or more sides, and a planar shape of each of the reflective pattern and the second pattern is elliptical or polygonal having four or more sides.

17 . The display device of claim 16 , wherein an area of the reflective pattern is equal to an area of the second pattern.

18 . The display device of claim 16 , wherein an area of the reflective pattern is less than an area of the second pattern.

19 . The display device of claim 16 , wherein a shape of the reflective pattern is identical to a shape of the second pattern in the plan view.

20 . The display device of claim 16 , wherein

the touch sensing layer comprises a touch insulating layer disposed on the display layer, and

the driving electrode and the reflective pattern are disposed directly on the touch insulating layer.

21 . An electronic device, comprising:

a display device configured to provide an image;

a processor configured to provide an image data signal to the display device;

a memory configured to store a data information for operation; and

a power module configured to generate power,

wherein the display device comprises:

a display layer comprising a light-emitting element and a pixel-defining layer;

a touch sensing layer disposed on the display layer and comprising a touch insulating layer and a reflective pattern; and

a light-blocking pattern disposed on the touch sensing layer and comprising a first pattern overlapping the pixel-defining layer and a second pattern overlapping the reflective pattern,

wherein the reflective pattern and the second pattern each overlap the light-emitting element in a plan view,

wherein the reflective pattern and the second pattern each have a vertical length and a horizontal length different from each other in the plan view, and

wherein the pixel-defining layer defines an emission area and a non-emission area, a planar shape of the emission area is circular, elliptical, or polygonal having four or more sides, and a planar shape of each of the reflective pattern and the second pattern is elliptical or polygonal having four or more sides.
