Abstract

Disclosed is a liquid crystal display comprising a first substrate including wiring, which intersects to define unit pixels, and a first electrode formed in each unit pixel; a second substrate provided opposing the first substrate at a predetermined distance and including a second electrode formed over an entire surface of the second substrate, the second electrode generating an electric field with the first electrode; and a liquid crystal layer injected between the first substrate and the second substrate and including liquid crystal molecules that are horizontally oriented in one direction, the liquid crystal molecules, as a result of the electric field generated between the first and second substrates, having a symmetrically bent alignment about an imaginary center plane parallel to the first and second substrates at a center position therebetween, wherein the first electrode is protruded in a direction toward the second substrate at edges where orientation for the liquid crystal molecules starts.

Claims (16)

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

a first substrate;

a second substrate facing the first substrate;

a pixel region formed between the first substrate and the second substrate;

a liquid crystal layer disposed between the first substrate and the second substrate;

an alignment layer formed over at least one of the first substrate and the second substrate and applying an orientation force to the liquid crystal layer; and

an insulating projection having a slant region, the projection formed on at least one of the first substrate and the second substrate, and disposed only near a first edge of the pixel region and influencing the liquid crystal layer to exhibit a stable bent alignment within the pixel region,

wherein the slant region has a portion extending obliquely from at least one of the surface of the first substrate and the surface of the second substrate

wherein a thickness of the insulating projection varies along with the slant region.

2. The LCD of claim 1 , wherein a direction from the first edge to a second edge of the pixel region facing the first edge is substantially the same with a direction of the orientation force.

3. The LCD of claim 2 , wherein the projection is formed on the first substrate.

4. The LCD of claim 1 , wherein a direction from the first edge to a second edge of the pixel region facing the first edge is substantially opposite to a direction of the orientation force.

5. The LCD of claim 4 , wherein the projection is formed on the second substrate.

6. The LCD of claim 1 , wherein the projection is formed by an insulating pattern formed on the first substrate or the second substrate.

7. The LCD of claim 6 , wherein the insulating pattern has a slanted edge portion.

8. The LCD of claim 6 , wherein the insulating pattern is formed of an organic insulating material.
