Abstract

A display panel includes an opposite substrate and an array substrate, the array substrate includes a first base substrate, a plurality of pixels and a color filter. The opposite substrate includes a second base substrate, a first black matrix and a second black matrix. The first black matrix maintains an interval between the second base substrate and the array substrate, and the first black matrix is formed to correspond to a display area to block light. The second black matrix includes a first area and a second area. The first area surrounds the color filter and the second area surrounds the first area. The second area includes a height different from a height of the first area when viewed in a plan view.

Claims (30)

1. A display panel comprising:

an opposite substrate; and

an array substrate;

wherein, the opposite substrate and the array substrate having a display area and a peripheral area surrounding the display area;

a first black matrix interposed between the opposite substrate and the array substrate, the first black matrix maintains an interval between the opposite substrate and the array substrate, and the first black matrix is disposed to correspond to the display area to block a light; and

a second black matrix disposed to correspond to the peripheral area to block the light, the second black matrix comprising a first area and a second area, the second area surrounds the first area, the second area including a height different from a height of the first area when viewed in a plan view, the first area and the second area are defined on the second black matrix.

2. The display panel of claim 1 , wherein the first area of the second black matrix includes a first height, the second area of the second black matrix includes a second height larger than the first height.

3. The display panel of claim 2 , wherein the first height is smaller than a distance between the array substrate and the opposite substrate.

4. The display panel of claim 3 , wherein the first black matrix includes the second height of the second black matrix, and the first black matrix makes contact with the array substrate.

5. The display panel of claim 1 , wherein the opposite substrate further comprises a common electrode which is disposed in an upper portion of the opposite substrate except for an area where the first black matrix is disposed to output a common voltage.

6. The display panel of claim 1 , wherein the first area of the second black matrix partially overlaps with the color filter when viewed in a plan view.

7. The display panel of claim 6 , wherein the color filter is disposed to correspond to the display area, and the second black matrix is spaced apart from the array substrate.

8. The display panel of claim 1 , wherein the array substrate further comprises a color filter and a pixel electrode.

9. The display panel of claim 8 , wherein the array substrate further comprises an insulating layer is disposed between the pixel electrode and the color filter.

10. The display panel of claim 8 , wherein the first black matrix partially overlap a source electrode of the thin film transistor and a drain electrode of the thin film transistor when viewed in a plan view.

11. The display panel of claim 8 , wherein the array substrate further comprises a thin film transistor including a gate electrode, a source electrode, and a drain electrode, and the first black matrix is disposed to correspond to an area including the thin film transistor.

12. The display panel of claim 1 , further comprising:

a liquid crystal layer interposed between the array substrate and the opposite substrate, the liquid crystal layer adjusts a transmittance of light according to an intensity of an electric field generated between the array substrate and the opposite substrate; and

a coupling member interposed between the array substrate and the opposite substrate while surrounding the liquid crystal layer, the coupling member seals the liquid crystal layer.

13. The display panel of claim 12 , wherein the coupling member is disposed in the peripheral area to surround the second black matrix and the coupling member is spaced apart from the second black matrix.

14. The display panel of claim 1 , wherein the first and second black matrices comprise a photoresist organic material including a black color, and the first and second black matrices are formed substantially simultaneously through a same process.

16. A display panel comprising:

an opposite substrate; and

an array substrate;

wherein the opposite substrate and the array substrate having a display area and a peripheral area surrounding the display area;

a black matrix disposed to correspond to the peripheral area to block the light, the black matrix surrounds the color filter, and the black matrix having a staircase shape.

17. The display panel of claim 16 , wherein the black matrix comprises a first area and a second area, the first area surrounds the color filter and the second area surrounds the first area when viewed in a plan view, the first area includes a first height, the second area includes a second height larger than the first height, and the first height is smaller than a distance between the array substrate and the opposite substrate.

18. The display panel of claim 17 , wherein the opposite substrate further comprises a spacer interposed between the opposite substrate and the array substrate, the spacer maintains an interval between the opposite substrate and the array substrate, and the spacer is disposed to correspond to the display area to block a light.

19. The display panel of claim 18 , wherein the spacer and the black matrix comprise a photoresist organic material including a black color, and the spacer and the black matrix are formed substantially simultaneously through a same process.
