PROBLEM TO BE SOLVED: To provide a liquid crystal display device adapted to simplify processing, and to provide a method for manufacturing the device. SOLUTION: The liquid crystal display device includes a gate line formed 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 forming the channel of the thin-film transistor and overlapped along the data line; a double-layer passivation film having a two-layer structure and covering the data line and the thin film transistor, wherein the two layers have different etching rates from each other; and a pixel electrode formed in a pixel hole, penetrating an upper passivation film of the double-layer passivation film in the pixel area and connected to the drain electrode of the thin-film transistor exposed through a drain contact hole, wherein the pixel electrode forms a border with the side face of the upper passivation film that surrounds the pixel hole.
