ABSTRACT:
A liquid crystal display device according to the present invention includes a gate line on a substrate; a data line crossing the gate line with a gate insulating film to define a pixel area; a thin film transistor connected to the gate line and the data line; a semiconductor pattern overlapped along the data line; a double layer passivation film covering the data line and the thin film transistor, wherein layers of the passivation film have different etching rates; and a pixel electrode formed in a pixel hole penetrating an upper passivation film of the double layer passivation film and connected to a drain electrode of the thin film transistor exposed through a drain contact hole, the pixel electrode forming a border with the upper passivation film surrounding the pixel hole.
