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 with the first signal line, a first color filter and a second color filter disposed on the first substrate; a colored member disposed on the first color filter and the second color filter; and a pixel electrode disposed on the first color filter and the second color filter and the colored member, wherein the first color filter and the second color filter are partially overlapped with each other and the height of the colored member disposed at the overlap between the first color filter and the second color filter is greater than the height of the colored member disposed not at the overlap.

wherein a maximum height on the first substrate of a first portion of the colored member disposed at the overlap between the first color filter and the second color filter is greater than a maximum height on the first substrate of a second portion of the colored member disposed not at the overlap between the first color filter and the second color filter.

2. The liquid crystal display of claim 1 , wherein:

the surface of the overlap where the first color filter and the second color filter are overlapped with each other is flat.

3. The liquid crystal display of claim 2 , wherein:

the width of the overlap of the first color filter and the second color filter is greater than or equal to approximately 7 μm.

4. The liquid crystal display of claim 3 , further comprising:

a spacer for maintaining a cell gap,

wherein the height of the colored member is less than the height of the spacer.

5. The liquid crystal display of claim 4 , wherein:

a difference in height between the colored member and the spacer is less than or equal to approximately 2 μm.

6. The liquid crystal display of claim 5 , wherein:

the difference in height between the colored member and the spacer is less than or equal to approximately 1.4 μm.

7. The liquid crystal display of claim 4 , wherein:

the spacer and the colored member are formed of the same layer.

8. The liquid crystal display of claim 4 , wherein:

the spacer comprises a first spacer and a second spacer that have different heights from each other, and

the colored member has a height less than a height of the first spacer and a height of the second spacer.

9. The liquid crystal display of claim 4 , further comprising:

a first signal line disposed on the first substrate,

wherein the overlap of the first color filter and the second color filter is partially overlapped with the first signal line.

10. The liquid crystal display of claim 9 , wherein:

the first signal line comprises a data line.

11. A liquid crystal display, comprising:

a first substrate;

a first color filter and a second color filter disposed on the first substrate;
