Abstract

Disclosed is a liquid crystal display comprising a first substrate made of an insulating material; pixel electrodes formed on the first substrate, the pixel electrodes having a first aperture pattern; a second substrate made of an insulating material and provided opposing the first substrate at a predetermined distance; a common electrode formed on the second substrate, the common electrode having a second aperture pattern; and a liquid crystal layer made of liquid crystal material that is injected between the first and second substrates, wherein either or both of the pixel electrodes and the common electrode include stepped portions that protrude a predetermined distance away from the substrates, between apertures of the first and/or second aperture patterns.

Claims (14)

1. A liquid crystal display (LCD), comprising:

a first substrate;

a pixel electrode formed on the first substrate and having a first aperture pattern;

a second substrate;

a common electrode formed on the second substrate and having a second aperture pattern,

wherein a gap between the pixel electrode and the common electrode is decreased at a portion between the first aperture pattern and the second aperture pattern.

2. The LCD of claim 1 , further comprising a first insulating layer formed on the first substrate.

3. The LCD of claim 2 , wherein the first insulating layer forms a plateau protruding from the first substrate.

4. The LCD of claim 2 , wherein the pixel electrode is formed on the first insulating layer.

5. The LCD of claim 4 , wherein the pixel electrode has a stepped portion.

6. The LCD of claim 2 , further comprising a second insulating layer formed on the second substrate.

7. The LCD of claim 6 , wherein the common electrode is formed on the second insulating layer.

8. The LCD of claim 6 , wherein the second insulating layer forms a plateau protruding from the second substrate.

9. The LCD of claim 5 , wherein the stepped portion of the pixel electrode is arranged between the first aperture pattern and the second aperture pattern.
