Abstract

A horizontal electric field-type liquid crystal display panel includes a plurality of scanning lines that are disposed parallel to each other, a common wiring, a plurality of signal lines that are disposed in a direction for intersecting the plurality of scanning lines, a switching element that is disposed near an intersection between the scanning line and the signal line, a first electrode formed in an area partitioned by the scanning line and the signal line, and a second electrode that is formed to be overlapped with the first electrode though an insulation film disposed on the first electrode and has a plurality of slits in the shape of a stripe. A shield electrode formed of a conductive material is formed on the surface of the insulation film disposed on the scanning line, and the shield electrode is connected to the common wiring through a contact hole formed on the common wiring.

Claims (21)

1. A horizontal electric field-type liquid crystal display panel comprising:

a plurality of scanning lines and common wirings that are disposed parallel to each other;

a plurality of signal lines that is disposed in a direction for intersecting the plurality of scanning lines;

a switching element that is disposed near an intersection between the scanning line and the signal line;

a first electrode formed in an area partitioned by the scanning line and the signal line; and

a second electrode that is formed to be overlapped with the first electrode though an insulation film disposed on the first electrode and has a plurality of slits in the shape of a stripe,

wherein a shield electrode formed of a conductive material is formed on the surface of the insulation film disposed on the scanning line, and

wherein the shield electrode is connected to the common wiring through a contact hole formed on the common wiring.

2. The horizontal electric field-type liquid crystal display panel according to claim 1 ,

wherein the first electrodes is connected to the common wiring,

wherein the second electrode is connected to the switching element though a first contact hole formed on an electrode of the switching element, and

wherein the shield electrode is connected to the common wiring through a second contact hole formed on the common wiring.

3. The horizontal electric field-type liquid crystal display panel according to claim 1 ,

wherein the first electrode is connected to the common wiring,

wherein the second electrode is connected to the switching element though a first contact hole formed on an electrode of the switching element, and

wherein the shield electrode is connected to the common wiring through a second contact hole formed on the common wiring and is connected to the first electrode of an adjacent pixel through a third contact hole formed on the first electrode of the adjacent pixel.

4. The horizontal electric field-type liquid crystal display panel according to claim 1 , wherein the shield electrode is formed of a same material as that of the second electrode.

5. The horizontal electric field-type liquid crystal display panel according to claim 1 ,

wherein the first electrode is connected to the switching element though a first contact hole formed on an electrode of the switching element, and

wherein the shield electrode is formed of a same material as that of the second electrode and is formed integrally with the second electrode.

6. The horizontal electric field-type liquid crystal display panel according to claim 1 , wherein the shield electrode coats a half or more of the scanning line.
