Abstract

A display device having a display element is configured such that the extending directions of electrodes are made different from each other among upper, lower, left and right pixels.

Claims (16)

1 . A liquid crystal display device comprising:

a first transparent insulating substrate;

a second transparent insulating substrates arranged opposite to the first substrate at a distance;

a liquid crystal layer is sandwiched between the first and second substrates;

a plurality of gate signal lines and a plurality of video signal lines formed on the first substrate,

a plurality of pixel regions defined by the video signal lines and the gate signal lines, the pixel areas having;

a thin film transistor element;

a pixel electrode which has a plurality of slits,

the direction of the slits formed in the pixel electrode differs between an upper region and a lower region of each pixel region,

the slit of the upper region and the slit of the lower region are divided in the center of the pixel region.

2 . A liquid crystal display device according to claim 1 , wherein the slits formed which is not parallel to the gate signal line and the video signal line.

3 . A liquid crystal display device according to claim 1 , wherein the direction of the slit of the upper region and the slit of the lower region are symmetrically formed on the central portion of the pixel region.

4 . A liquid crystal display device according to claim 1 , wherein the slits of the upper region and the slits of the lower region of the central portion of the pixel region are arranged alternately each other in a parallel direction for the gate signal line.

5 . A liquid crystal display device according to claim 1 , wherein the pixel region has a common electrode which has a plane shape, the common electrode is overlapped to the slits of the pixel electrode.

6 . A liquid crystal display device according to claim 1 , wherein the length of the slit of the central portion of the pixel region has a shorter than the length of other slits.

7 . A liquid crystal display device according to claim 1 , wherein the length of the slit adjacent to the gate signal line is shorter than the length of other slits.
