Abstract

A liquid crystal display includes: a substrate; a pixel electrode disposed on the substrate and having a first subpixel electrode and a second subpixel electrode; and a common electrode facing the pixel electrode, wherein the first subpixel electrode has a pair of bent edges substantially parallel to each other, the second subpixel electrode has a pair of bent edges substantially parallel to each other, and the second subpixel electrode has a height greater than a height of the first subpixel electrode.

Claims (15)

1. A liquid crystal display comprising:

a substrate;

a pixel electrode disposed on the substrate and including a first subpixel electrode and a second subpixel electrode; and

a common electrode facing the pixel electrode,

wherein the first subpixel electrode has a pair of bent edges substantially parallel to each other,

the second subpixel electrode has a pair of bent edges substantially parallel to each other, and

the second subpixel electrode has a height greater than a height of the first subpixel electrode,

wherein a convexity and a concavity of the bent edges of the first and the second subpixel electrodes are reversed relative to each other.

2. The liquid crystal display of claim 1 , wherein the first subpixel electrode and the second subpixel electrode are adjacent in a length direction.

3. The liquid crystal display of claim 1 , wherein the first subpixel electrode and the second subpixel electrode are adjacent in a height direction.

4. The liquid crystal display of claim 1 , wherein the first subpixel electrode has a length substantially equal to a length of the second subpixel electrode.

5. The liquid crystal display of claim 4 , wherein the height of the second subpixel electrode is about twice the height of the first subpixel electrode.

6. The liquid crystal display of claim 1 , wherein each of the bent edges of the first and second subpixel electrodes has a bent point, and each of the first and the second subpixel electrodes has a symmetry with respect to a straight line connecting the bent points.

7. The liquid crystal display of claim 1 , wherein each of the pairs of bent edges comprise a concave edge and a convex edge, and the convex edge of the first subpixel electrode is adjacent to the concave edge of the second subpixel electrode or the concave edge of the fltst subpixel electrode is adjacent the convex edge of the second subpixel electrode.

8. The liquid crystal display of claim 1 , wherein each of the pairs of bent edges include a concave edge and a convex edge, the concave edge of the first subpixel electrode is connected to the convex edge of the second subpixel electrode, and the convex edge of the first subpixel electrode is connected to the concave edge of the second subpixel electrode.
