Abstract

A display device is provided including a substrate. The substrate includes a pixel area and a light-blocking area. A light-emitting element is arranged in the pixel area of the substrate. An insulating layer is disposed on the substrate. The insulating layer has an opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area. A light control pattern at least partially surrounds the insulating pattern of the insulating layer and is arranged in the opening corresponding to the light-blocking area.

Claims (26)

1. A display device, comprising:

substrate including a pixel area and a light-blocking area;

a light-emitting element arranged the pixel area of the Substrate;

an insulating layer disposed on the substrate, wherein the insulating layer has an opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area; and

a light control pattern least partially surrounding the insulating pattern of the insulating layer and arranged in the opening corresponding to the light-blocking area,

wherein the opening of the insulating layer and the tight control pattern do not overlap the light-emitting element.

2. The display device of claim 1 , wherein the light control pattern includes a reflective pattern and a light-blocking pattern, wherein the reflective pattern and the light-blocking pattern are both arranged on a side and a bottom of the opening, and wherein the light-blocking pattern is arranged on the reflective pattern.

3. The display device of claim 2 , further comprising: a level pattern at least partially covering the light control pattern.

4. The display device of claim 3 , wherein an upper surface of the level pattern is coplanar with an upper surface of the light control pattern.

5. The display device of claim 1 , wherein the light control pattern includes a reflective pattern and a light-blocking pattern, wherein the reflective pattern is arranged on a side and a bottom of the opening, wherein the light-blocking pattern is arranged on the bottom of the opening, and wherein the reflective pattern is arranged on the light-blocking pattern.

6. The display device of claim 5 , further comprising: a level pattern at least partially covering the light control pattern.

7. The display device of claim 1 , further comprising: an encapsulation layer disposed between the light control pattern and the light-emitting element.

8. A display device, comprising:

a substrate including a pixel area and a light-blocking area;

a light-emitting element arranged in the pixel area of the substrate;

an insulating layer disposed on the substrate, wherein the insulating layer has an opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area; and

a light control pattern at least partially surrounding the insulating pattern of the insulating layer and arranged in the opening corresponding to the light-blocking area,

wherein the light control pattern includes a reflective pattern and a light-blocking pattern, wherein the reflective pattern is arranged on a side and a bottom of the opening, wherein the light-blocking pattern is arranged on the bottom of the opening, and wherein the reflective pattern is arranged on the light-blocking pattern,

wherein the display device further comprises a level pattern at least partially covering the light control pattern, and

wherein an upper surface of the level pattern is coplanar with the reflective pattern.

9. A display device, comprising:

a substrate including a pixel area and a light-blocking area;

a light-emitting element arranged in the pixel area of the substrate;

an insulating layer disposed on the substrate, wherein the insulating layer has opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area, and

a light control pattern at least partially surrounding the insulating pattern of the insulating layer and arranged the opening corresponding to the light-blocking area,

wherein the light control pattern includes a reflective pattern, a support pattern, and a light-blocking pattern, wherein the reflective pattern and the support pattern are both arranged on a side and a bottom of the opening, wherein the light-blocking pattern is arranged on the bottom of the opening, wherein the support pattern is arranged under the reflective pattern, and wherein the light-blocking pattern is arranged under the support pattern.
