Abstract

A thin film transistor panel for a liquid crystal display includes a substrate, a plurality of data lines formed over the substrate and extending in a first direction, and a plurality of gate lines formed over the substrate and extending in a second direction. The plurality of gate lines cross the plurality of data lines to form a plurality of pixel areas, each of the plurality of pixel areas having a multi-bent band shape. Each of a plurality of pixel electrodes are formed in a corresponding pixel area.

Claims (22)

1. A liquid crystal display comprising:

a thin film transistor panel comprising:

a first substrate;

a plurality of data lines formed over the first substrate and extending in a first direction;

a plurality of gate lines formed over the first substrate and extending in a second direction, the plurality of gate lines crossing the plurality of data lines to form a plurality of pixel areas, each of the plurality of pixel areas having a multi-bent band shape; and

a plurality of pixel electrodes each formed in a corresponding pixel area, and each of the plurality of data lines comprise a first set of oblique portions and a second set of oblique portions, the first set of oblique portions being angled counterclockwise by about 45° from the plurality of gate lines and the second set of oblique portions being angled clockwise by about 45° from the plurality of gate lines;

a common electrode panel, comprising:

a second substrate; and

a common electrode formed over the second substrate; and

a liquid crystal layer formed between the thin film transistor panel and the common electrode panel and comprising liquid crystal molecules aligned vertical to surface of the first substrate when no voltage is applied, the liquid crystal layer having negative dielectric anisotropy.

2. The liquid crystal display of claim 1 , wherein each of the plurality of data lines is curved periodically to form the multi-bent band shaped pixel areas.

3. The liquid crystal display of claim 1 , wherein each of the plurality of pixel electrodes comprises a cutout extending in the second direction that divides each of the plurality of pixel electrodes in to a first portion and a second portion.

4. The liquid crystal display of claim 1 , further comprising:

a plurality of color filters formed over the passivation layer, the plurality of pixel electrodes formed over the plurality of color filters.

5. The thin film transistor panel of claim 1 , further comprising:

a plurality of storage electrode lines formed over the substrate and extending substantially in the second direction.

6. The thin film transistor panel of claim 5 , further comprising:

a plurality of sets of storage electrodes connected to each storage electrode line, each set of storage electrodes comprising a pair of first storage electrodes extending substantially in the first direction and a second storage electrode that connects the first storage electrodes; and

a plurality of connectors that connect the first storage electrodes in neighboring sets of storage electrodes.

7. The thin film transistor panel of claim 6 , wherein each of the first storage electrodes is curved periodically.

8. The liquid crystal display of claim 1 , further comprising:

a black matrix formed on second substrate, the common electrode formed over the black matrix.
