Abstract

A liquid crystal display is provided. The liquid crystal display includes a first display substrate, a second display substrate which faces the first display substrate, and a liquid crystal layer which is disposed between the first display substrate and the second display substrate. The first display substrate comprises a first base substrate, a reflective electrode which is disposed on the first base substrate, and a pixel electrode which is disposed on the reflective electrode. The second display substrate comprises a second base substrate, a color filter layer which comprises a first color filter disposed on a surface of the second base substrate which faces the first base substrate and a second color filter configured to display a different color from the first color filter, a protruding pattern which is formed on a surface of the color filter layer facing the first base substrate and which extends along a boundary between the first color filter and the second color filter, and reflective members which are disposed on sidewalls of the protruding pattern.

Claims (22)

1. An LCD comprising:

a first display substrate:

a second display substrate which faces the first display substrate; and

a liquid crystal layer which is disposed between the first display substrate and the second display substrate,

wherein the first display substrate comprises a first base substrate, a reflective electrode which is disposed on the first base substrate, a pixel electrode which is disposed on the reflective electrode, a protruding pattern which is disposed on the pixel electrode, and reflective members which are disposed on sidewalls of the protruding pattern,

wherein the second display substrate comprises:

a second base substrate, and

a color filter layer which comprises a first color filter disposed on a surface of the second base substrate which faces the first base substrate, and a second color filter configured to display a different color from that of the first color filter, and

wherein the protruding pattern extends along a boundary between the first color filter and the second color filter.

2. The LCD of claim 1 , wherein two of the reflective members are separated from each other.

3. The LCD of claim 1 , wherein the boundary between the first color filter and the second color filter is formed by an overlap between the first color filter and the second color filter.

4. An LCD comprising:

a first display substrate:

a second display substrate which faces the first display substrate; and

a liquid crystal layer which is disposed between the first display substrate and the second display substrate,

wherein the first display substrate comprises a first base substrate, an organic film which is disposed on the first base substrate and which comprises a flat portion having a flat upper surface and a protruding portion protruding from the flat portion toward the second display substrate, a reflective electrode which comprises a first reflective portion disposed on the flat portion and second reflective portions disposed on sidewalls of the protruding portion, and a pixel electrode which is disposed on the reflective electrode, and

wherein the second display substrate comprises a second base substrate, and a color filter layer which comprises a first color filter disposed on a surface of the second base substrate that faces the first base substrate and a second color filter configured to display a different color from that of the first color filter.

5. The LCD of claim 4 , wherein the protruding portion extends along a boundary between the first color filter and the second color filter.

6. The LCD of claim 5 , wherein the boundary between the first color filter and the second color filter is formed by an overlap between the first color filter and the second color filter.

7. The LCD of claim 4 , wherein the pixel electrode is a light transmissive electrode.

8. The LCD of claim 4 , wherein two of the second reflective portions are separated from each other.

9. The LCD of claim 4 , wherein the organic film is formed using a halftone mask.
