Abstract

A liquid crystal display includes first and second substrates opposed to each other with liquid crystal therebetween, the first substrate having a plurality of drain signal lines and gate signal lines, and a plurality of pixel regions defined by the drain signal lines and the gate signal lines. The pixel region has a first electrode formed of a transparent conducting layer having a plurality of slits, a second electrode formed of a transparent conducting layer, and an insulating layer interposed between the first electrode and the second electrode. The second electrode is overlapped with a plurality of the slits of the first electrode in the pixel region, the first electrode is overlapped with the drain signal line and the gate signal line, and at least one of the first electrode and the second electrode is formed between the first substrate and the liquid crystal layer in the pixel region.

Claims (15)

1. A liquid crystal display comprising:

a first substrate and a second substrate opposed to each other with liquid crystal therebetween, the first substrate having a plurality of drain signal lines and a plurality of gate signal lines; and

a plurality of pixel regions defined by the drain signal lines and the gate signal lines;

the pixel region having:

a first electrode formed of a transparent conducting layer having a plurality of slits;

a second electrode formed of a transparent conducting layer without slits; and

an insulating layer interposed between the first electrode and the second electrode;

wherein the second electrode is overlapped with a plurality of the slits of the first electrode in the pixel region, the first electrode is overlapped with the drain signal line and the gate signal line; and

wherein at least one of the first electrode and the second electrode is formed between the first substrate and the liquid crystal layer in the pixel region.

2. The liquid crystal display according to claim 1 , wherein the first electrode is formed between the second electrode and the liquid crystal layer.

3. The liquid crystal display according to claim 2 , wherein the first electrode is a counter electrode and the second electrode is a pixel electrode; and

the pixel region each have a thin-film transistor connected to the drain signal line and have a counter voltage signal line that feeds an electric signal to the counter electrode.

4. The liquid crystal display according to claim 3 , wherein a plurality of the slits of the counter electrode is arranged at the position that does not overlap with the gate signal line and the drain signal line.

5. The liquid crystal display according to claim 1 , further comprising:

a spacer formed on the gate signal lines between the first substrate and the second substrate.
