Abstract

A thin film transistor array panel is provided, which includes: a substrate; a plurality of first signal lines formed on the substrate; a plurality of second lines formed on the substrate, intersecting the first signal line, and including a plurality of curved portions having at least two curve points and a plurality of intermediate portions, the curved portions and the intermediate portions alternately connected; a plurality of pixel electrodes located substantially in areas defined by the first and the second signal lines; and a plurality of thin film transistors connected to the first and the second signal lines and the pixel electrodes.

Claims (24)

1. A liquid crystal display comprising:

a first substrate;

a gate line disposed on the first substrate and including a gate electrode;

a gate insulating layer disposed on the gate line;

a semiconductor layer disposed on the gate insulating layer;

a data line disposed on first the substrate and including a curved portion having at least two curved points and including a source electrode disposed on the semiconductor layer at least in part;

a drain electrode disposed on the semiconductor layer at least in part and disposed opposite the source electrode;

a passivation layer disposed on the semiconductor layer;

a pixel electrode having an edge curved along the data line,

a second substrate facing the first substrate;

a common electrode formed on the second substrate;

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

at least a domain defining member disposed on at least one of the first and the second substrates and partitioning the liquid crystal layer into a plurality of domains, each domain having two major edges substantially parallel to the curved portion of the data line,

wherein two end portions of the two major edges of the domain defining member are curved, and

wherein one of the two end portions is substantially parallel to the gate line, and the other is substantially parallel to a longitudinal portion of the data line.

2. The liquid crystal display of claim 1 , further comprising a storage electrode line that extends substantially parallel to the gate line and has a storage electrode overlapping a conductor connected to the pixel electrode to form a storage capacitor.

3. The liquid crystal display of claim 1 , wherein the pixel electrode is disposed on the passivation layer.

4. The liquid crystal display of claim 1 , wherein the passivation layer comprises organic or inorganic insulating material.

5. The liquid crystal display of claim 1 , further comprising a color filter formed on the passivation layer.

6. The liquid crystal display of claim 5 , wherein the color filter extends substantially parallel to the data line.

7. The liquid crystal display of claim 1 , wherein the semiconductor layer has substantially the same planar shape as the data line, the source electrode, and the drain electrode except for a first portion.

8. The liquid crystal display of claim 1 , wherein the liquid crystal layer has negative dielectric anisotropy and is vertically aligned.

9. The liquid crystal display of claim 1 , wherein the domain defining member comprises a cutout in the pixel electrode or the common electrode.

10. The liquid crystal display of claim 1 , wherein the curved portion of the data line comprises a plurality of portions making a clockwise angle of about 45 degrees and a counterclockwise angle of about 45 degrees with respect to the gate line.
