Abstract

The present invention relates to a display panel that includes a substrate; a first partition arranged on the substrate, defining a first region, and having an undercut; a second partition arranged outside the first partition; a color filter arranged on the substrate and positioned in the first region; and a common electrode arranged on the color filter.

Claims (69)

1. A display panel, comprising:

a substrate;

a first partition arranged on the substrate, defining a first region, and comprising an undercut;

a second partition arranged outside the first partition;

a color filter arranged on the substrate and positioned in the first region; and

a common electrode arranged on the color filter,

wherein the first partition further comprises a hydrophilic material, and the second partition comprises a hydrophobic material.

2. The display panel of claim 1 , wherein

the first partition further comprises an opening exposing the substrate, and the second partition further comprises a transverse portion and a longitudinal portion,

wherein the longitudinal portion is positioned in the opening, and the transverse portion is positioned on the first partition.

3. The display panel of claim 2 , further comprising:

a first interface arranged by the color filter and the first partition; and

a second interface arranged by the color filter and the transverse portion,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

4. The display panel of claim 3 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.

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

a first interface formed by the color filter and the first partition; and

a second interface formed by the color filter and the second partition,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

6. The display panel of claim 5 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.

7. A display panel comprising:

a substrate;

a gate line and a data line arranged on the substrate and intersecting each other;

a thin film transistor connected to the gate line and the data line;

a passivation layer arranged on the thin film transistor;

a first partition arranged on the passivation layer, defining a pixel, and comprising an undercut;

a second partition arranged outside the first partition;

a color filter arranged on the passivation layer and in the pixel; and

a pixel electrode arranged on the color filter and connected to the thin film transistor.

8. The display panel of claim 7 , wherein

the first partition further comprises a hydrophilic material, and the second partition comprises a hydrophobic material.

9. The display panel of claim 8 , wherein

the first partition further comprises an opening exposing the substrate, and the second partition comprises a transverse portion and a longitudinal portion,

wherein the longitudinal portion is positioned in the opening, and the transverse portion is positioned on the first partition.

10. The display panel of claim 9 , further comprising:

a first interface formed by the color filter and the first partition; and

a second interface formed by the color filter and the transverse portion,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

11. The display panel of claim 10 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.

12. The display panel of claim 8 , further comprising:

a first interface formed by the color filter and the first partition; and

a second interface formed by the color filter and the second partition,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

13. The display panel of claim 12 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.

14. The display panel of claim 7 , wherein

the first partition further comprises an opening exposing the substrate, and the second partition comprises a transverse portion and a longitudinal portion,

wherein the longitudinal portion is positioned in the opening, and the transverse portion is positioned on the first partition.

15. The display panel of claim 14 , further comprising:

a first interface formed by the color filter and the first partition; and

a second interface formed by the color filter and the transverse portion,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

16. The display panel of claim 15 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.

17. The display panel of claim 7 , further comprising:

a first interface formed by the color filter and the first partition; and

a second interface formed by the color filter and the second partition,

wherein the second interface is disposed inside the first interface, and the color filter is formed to the second interface.

18. The display panel of claim 17 , wherein

the ratio of the thickness of the transverse portion to the thickness of the first partition is 1:3, and

the ratio of the distance between the second interface and the first interface to the width of the transverse portion is 1:5.
