Abstract

A liquid crystal display device is disclosed that may prevent crosstalk from occurring. The liquid crystal display device includes pixel and common electrodes forming a fringe field, wherein the pixel electrodes are substantially in parallel over the common electrode and the pixel electrodes are connected with one another in a central portion.

Claims (14)

1. A liquid crystal display device, comprising:

pixel and common electrodes forming a fringe field in a pixel,

wherein the pixel electrodes are formed in parallel over the common electrode, and the pixel electrodes are connected with one another in a central portion and the pixel electrodes overlaps over the common electrode for forming the fringe field, and

further wherein a width between two ends of the adjacent pixel electrodes is smaller than a width between two central portions of the adjacent pixel electrodes in the pixel.

2. The device of claim 1 , wherein the width of the end of pixel electrode is larger than the width of the central portion of pixel electrode.

3. The device of claim 1 , wherein the width of the central portion of pixel electrode is smaller than the width of the end of each pixel electrode.

4. The device of claim 1 , wherein the pixel electrodes have a plane shape.

5. A method of fabricating for a liquid crystal display device, comprising:

forming a common electrode in a pixel; and

forming a plurality of pixel electrodes in parallel over the common electrode, and a central connection line connected with the plurality of pixel electrodes over the common electrode in a central portion of the pixel, wherein the common and pixel electrodes, including the connection line, forms a fringe field, wherein the pixel electrodes and the connection line overlap over the common electrode in the pixel; and

further wherein a width between two ends of the adjacent pixel electrodes, among the plurality of pixel electrodes in parallel, is smaller than a width between two central portion of the adjacent pixel electrodes.

6. The method of claim 5 , wherein the width of the end of pixel electrode is larger than the width of the central portion of pixel electrode.

7. The method of claim 5 , wherein the width of the central portion of pixel electrode is smaller than the width of the end of the pixel electrode.

8. The method of claim 5 , wherein the pixel electrodes are formed in a plane shape.
