Abstract

A liquid crystal display includes a pixel electrode, a common electrode facing the pixel electrode, and a thin film transistor including a gate electrode connected to a gate line, a source electrode connected to a data line, and a drain electrode connected to the pixel electrode. First and second domain defining members defining domains are provided at the liquid crystal display and the drain electrode is disposed near a corner of one of the domains. The drain electrode has an edge extending perpendicular to major edges of the domains and located closest to a center of the one of the domains.

Claims (17)

1. A liquid crystal display comprising:

a first substrate;

a gate line formed on the first substrate;

a data line formed on the first substrate and intersecting the gate line;

a pixel electrode disposed substantially in an area defined by the gate line and the data line;

a thin film transistor including a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode;

a second substrate facing the second substrate;

a common electrode formed on the second substrate;

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

first and second domain defining members defining a plurality of domains in the liquid crystal layer,

wherein the drain electrode is disposed near a corner of one of the domains;

wherein each domain has a pair of major edges extending parallel to each other; and

wherein the drain electrode has a plurality of edges and the edges of the drain electrode include a first edge extending perpendicular to the major edges of the domains and located closest to a center of the one of the domains.

2. The liquid crystal display of claim 1 , wherein the major edges of the domains make an angle of about 45 degrees with the gate line.

3. The liquid crystal display of claim 1 , wherein the drain electrode has a first edge perpendicular to the major edges of the one of the domains.

4. The liquid crystal display of claim 1 , wherein the first and the second domain defining members include cutouts provided in the pixel electrode and the common electrode.

5. The liquid crystal display of claim 1 , further comprising a storage electrode overlapping the first domain defining member.
