Abstract

It is disclosed a liquid crystal display having an electrode pad for compensating for differences in resistance of electrode links. The liquid crystal display including a pixel area and a driving circuit, comprises at least two electrode links each extended from the pixel area; and at least two pads in contact with the driving circuit and the electrode links, each pad being in contact with each electrode link and having a non-resistivity that depends on a length of the each electrode link. Accordingly, resistance differences that depend on the length of the electrode links are compensated for using electrode pads, thereby making signal conductors with substantially equal resistances.

Claims (9)

1. A liquid crystal display including a pixel area and a driving circuit, comprising:

at least two electrode links each extended from the pixel area; and

at least two pads in contact with the driving circuit and the electrode links, each pad being in contact with each electrode link and having a non-resistivity that depends on a length of the each electrode link.

2. A liquid crystal display according to claim 1 , wherein the each pad includes:

an electrode pad connected to the electrode link; and

a transparent electrode in contact with the driving circuit and the electrode pad,

wherein any one of the electrode pad and the transparent electrode varies along with the length of the electrode links in its non-resistivity.

3. A liquid crystal display according to claim 2 , wherein when the electrode link has a relatively long length, the any one of the electrode pad and the transparent electrode has a relatively low non-resistivity.

4. A liquid crystal display according to claim 2 , wherein, when the electrode link has a relatively short length, the any one of the electrode pad and the transparent electrode has a relatively high non-resistivity.
