Abstract

A liquid crystal display includes a first substrate, a second substrate, a liquid crystal disposed between the first substrate having drain lines and gate signal lines defining pixel regions and the second substrate. The pixel regions include a pixel electrode formed of a transparent conducting layer and having a plurality of slits, a common electrode formed of a transparent conducting layer, the common electrode being overlapped with the pixel electrode through an insulating layer, and the liquid crystal being driven by an electric field generated by the pixel electrode and the common electrode. A conductor layer is arranged proximate to the drain signal line. The conductor layer is placed at a position where at least a part thereof overlaps the common electrode, and the conductor layer is not connected to the drain signal line and the pixel electrode electrically.

Claims (14)

1. A liquid crystal display comprising:

a first substrate;

a second substrate;

a liquid crystal disposed between the first substrate and the second substrate,

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 regions including:

a pixel electrode formed of a transparent conducting layer and having a plurality of slits;

a common electrode formed of a transparent conducting layer, the common electrode being overlapped with the pixel electrode through an insulating layer, the liquid crystal being driven by an electric field generated by the pixel electrode and the common electrode;

wherein a conductor layer is arranged proximate to the drain signal line, and the conductor layer is placed at a position where at least a part thereof overlaps the common electrode; and

wherein the conductor layer is not connected to the drain signal line, the common electrode and the pixel electrode electrically.

2. The liquid crystal display according to claim 1 , wherein the conductor layer is arranged at the position that does not overlap with the pixel electrode.

3. The liquid crystal display according to claim 1 , wherein the conductor layer extends in a direction of a direction of extension of the drain signal line.

4. The liquid crystal display according to claim 1 , wherein the common electrode overlaps the gate signal line and does not overlap the drain signal line, the common electrode being connected to the common electrode of an adjacent pixel region on the gate signal line.
