Liquid crystal display
View Patent ↗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.
1. A liquid crystal display (LCD), comprising:
a first substrate;
a second substrate facing the first substrate and opposite thereto;
an electrode formed on at least one of the first and second substrates;
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; and
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,
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 , further comprising:
a gate line formed on the first substrate;
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; and
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,
wherein the 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.
3. The LCD of claim 2 , wherein the protrusion is formed at a first edge of the pixel region.
4. The LCD of claim 3 , 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.
5. The LCD of claim 4 , wherein the protrusion is formed on the first substrate.
6. The LCD of claim 3 , 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.
7. The LCD of claim 6 , wherein the protrusion is formed on the second substrate.
8. The LCD of claim 3 , wherein the protrusion is formed by a protrusion pattern formed on the first substrate or the second substrate.
9. The LCD of claim 8 , wherein the protrusion pattern is formed of an organic insulating material.
10. The LCD of claim 1 , wherein the protrusion is formed on a protection layer intermediate the electrode formed on at least one of the first and second substrates and the protrusion.
