Abstract

A liquid crystal display according to an exemplary embodiment of the present invention includes: a first substrate; a first signal line disposed on the first substrate; a thin film transistor connected to the first signal line; a color filter and a light blocking member disposed on the first substrate; a pixel electrode disposed on the color filter and the light blocking member; and a colored member formed on the pixel electrode and disposed on the light blocking member, the colored member having an upper surface that is generally planar with an upper surface of the color filter.

Claims (46)

1. A liquid crystal display comprising:

a first substrate;

a gate line disposed on the first substrate, the gate line extending along a first direction;

a data line disposed on the first substrate, the data line extending along a second direction perpendicular to the first direction;

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

a storage electrode disposed on the first substrate;

a color filter disposed on the first substrate;

a light blocking member disposed on the gate line, the data line and the thin film transistor;

a pixel electrode disposed on the color filter and the light blocking member; and

a colored member formed on the pixel electrode and disposed on the light blocking member,

wherein the light blocking member includes a first light blocking portion,

wherein the colored member includes a first colored portion, and

wherein each of the first light blocking portion and the first colored portion extends generally along the gate line and generally covers the gate line and the thin film transistor.

2. The liquid crystal display of claim 1 , further comprising:

wherein the light blocking member further includes a second light blocking portion and the colored member further includes a second colored portion, and

wherein the second light blocking portion and the second color portion extend generally along a data line and at least partially overlap the data line.

3. The liquid crystal display of claim 1 , wherein

the liquid crystal display further includes a spacer to maintain a cell interval, and

the colored member has a height lower than the spacer.

4. The liquid crystal display of claim 3 , wherein

the spacer is formed in the same layer as the colored member.

5. The liquid crystal display of claim 1 , wherein

the light blocking member has a height lower than the color filter in a region where the light blocking member is proximate to the color filter.

6. The liquid crystal display of claim 5 , wherein

the cell interval is substantially uniform at the region where the colored member is disposed and the region where the color filter is disposed throughout the region where the light blocking member is proximate to the color filter.

7. The liquid crystal display of claim 1 , further comprising:

a second substrate facing the first substrate; and

a liquid crystal layer interposed between the first substrate and the second substrate and including a plurality of liquid crystal molecules,

wherein, for a boundary region where the color filter is proximate to the light blocking member, the liquid crystal molecules disposed in the boundary region are pre-tilted in substantially the same direction as the liquid crystal molecules outside the boundary region and disposed on the color filter.

8. The liquid crystal display of claim 7 ,

wherein the liquid crystal molecules disposed in the boundary region are pre-tilted according to branch electrodes.

9. The liquid crystal display of claim 8 , further comprising

a first polarizer and a second polarizer disposed on outer surfaces of, respectively, the first substrate and the second substrate,

wherein the transmissive axes of the first polarizer and the second polarizer are crossed, and

wherein the liquid crystal molecules are oriented parallel to the first substrate and the second substrate when an electric field is applied thereto.

10. The liquid crystal display of claim 1 , wherein the first colored portion completely covers the gate line.

11. The liquid crystal display of claim 1 , wherein the first colored portion completely covers the thin film transistor.

12. The liquid crystal display of claim 1 , further comprising a second thin film transistor, wherein the first colored portion further covers the second thin film transistor.

13. The liquid crystal display of claim 12 , further comprising a third thin film transistor, wherein the first colored portion further covers the third thin film transistor.

14. The liquid crystal display of claim 2 , wherein the colored member comprising a spacer to maintain a cell interval.

15. The liquid crystal display of claim 14 , wherein an upper surface of the colored member is substantially planar with an upper surface of adjacent color filter.

16. The liquid crystal display of claim 15 , further comprising a passivation layer formed between the colored member and the light blocking member.

17. The liquid crystal display of claim 14 , further comprising a passivation layer formed between the colored member and the light blocking member.

18. The liquid crystal display of claim 2 , wherein an upper surface of the colored member is substantially planar with an upper surface of adjacent color filter.

19. The liquid crystal display of claim 18 , further comprising a passivation layer formed between the colored member and the light blocking member.

20. The liquid crystal display of claim 2 , further comprising a passivation layer formed between the colored member and the light blocking member.
