Abstract

A liquid crystal display is provided, which includes: a substrate; a field-generating electrode formed on the substrate; and a slope member formed on the substrate and having an inclination angle smaller than about 45 degrees.

Claims (26)

1. A thin film transistor array panel comprising:

a first signal line;

a second signal line intersecting the first signal line;

a thin film transistor connected to the first signal line and the second signal line;

a pixel electrode connected to the thin film transistor; and

an aligning member extending substantially parallel to the second signal line, overlapping the second signal line, and having an edge closer to the pixel electrode than the second signal line,

wherein the aligning member is electrically floating.

2. The thin film transistor array panel of claim 1 , wherein the aligning member and the pixel electrode are disposed on the same layer.

3. A thin film transistor array panel comprising:

a first signal line;

a second signal line intersecting the first signal line;

a thin film transistor connected to the first signal line and the second signal line;

a pixel electrode connected to the thin film transistor; and

an aligning member extending substantially parallel to the second signal line, overlapping the second signal line, and having an edge closer to the pixel electrode than the second signal line,

wherein the aligning member has substantially the same voltage as the second signal line.

4. A liquid crystal display comprising:

a first panel including a first signal line, a second signal line intersecting the first signal line, a thin film transistor connected to the first signal line and the second signal line, a pixel electrode connected to the thin film transistor, and an aligning member extending substantially parallel to the second signal line and having an edge closer to the pixel electrode than the second signal line;

a second panel facing the first panel and including a common electrode formed thereon; and

a liquid crystal layer disposed between the first panel and the second panel,

wherein the aligning member is electrically floating or has substantially the same voltage as the second signal line.

5. The liquid crystal display of claim 4 , further comprising a tilt direction determining member disposed on at least one of the first and the second panels and determining tilt directions of liquid crystal molecules of the liquid crystal layer.

6. The liquid crystal display of claim 5 , wherein the liquid crystal layer has negative dielectric anisotropy and is subjected to vertical alignment.

7. The liquid crystal display of claim 5 , wherein the tilt direction determining member comprises a cutout formed at the pixel electrode or the common electrode.

8. The liquid crystal display of claim 7 , wherein the tilt direction determining member has a width ranging about 9-12 microns.

9. The liquid crystal display of claim 5 , wherein the tilt direction determining member makes an angle of about 45 degrees with the first signal line.

10. The liquid crystal display of claim 5 , wherein the tilt direction determining member comprises a protrusion formed on the pixel electrode or the common electrode.
