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 (19)

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

a first substrate;

a gate line formed on the first substrate;

a second substrate facing the first substrate and opposite thereto;

a data line formed on the first substrate and intersecting the gate line, wherein the intersection of the gate line and the data line defines the pixel region;

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;

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

an electrode formed on at least one of the first and second substrates comprises a pixel electrode formed at the pixel region on the first substrate;

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

a protrusion formed on at least one of the first substrate and the second substrate, the protrusion extending obliquely from the at least one of the first substrate and the second substrate and influencing the liquid crystal layer to exhibit a stable bent alignment within the pixel region; and

a slant region formed on at least one of the first substrate and the second substrate near a first edge of the pixel region,

wherein a base of the protrusion formed on at least one of the first substrate and the second substrate is located equidistant to or further from the opposing substrate than a base defining the electrode extending from one of the first and second substrates.

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 slant region 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 slant region is formed on the second substrate.

6. The LCD of claim 1 , wherein the slant region 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.
