Abstract

An in-plane switching mode liquid crystal display device includes first and second substrates, a gate line and a data line arranged along first and second directions on the first substrate to define a pixel area, a passivation layer on the first substrate except within the pixel area, a light blocking system on the first substrate and on a stepped portion of the passivation layer adjacent to the data line, a plurality of common electrodes disposed within the pixel area, at least one of the common electrodes overlap a portion of the data line, and a plurality of pixel electrodes disposed within the pixel area, wherein the pixel electrodes and the common electrodes form a lateral electric field.

Claims (17)

1. An in-plane switching mode liquid crystal display device, comprising:

a gate line and a light blocking line on a first substrate;

a data line on the first substrate to define a pixel area;

a plurality of pixel electrodes within the pixel area to be parallel with the data line;

an organic layer along an entire surface of the first substrate except for the pixel electrodes; and

a plurality of common electrodes on the first substrate,

wherein at least one of the common electrodes is provided along an outer portion of the pixel area to overlap the data line.

2. The device according to claim 1 , wherein the common electrodes include at least one of ITO and IZO.

3. A method of fabricating an in-plane switching mode liquid crystal display device, comprising:

forming a gate line and a light blocking line on a first substrate;

forming a data line on the first substrate to define a pixel area;

forming a plurality of pixel electrodes within the pixel area to be parallel with the data line;

forming an organic layer along an entire surface of the first substrate;

exposing the pixel electrodes by removing a portion of the organic layer; and

forming a plurality of common electrodes on the first substrate,

wherein at least one of the common electrodes along an outer portion of the pixel area overlap the data line.

4. The method according to claim 3 , wherein the common electrodes include at least one of ITO and IZO.
