Patent ID: 7256076

Claim:
A method for manufacturing a liquid crystal display device comprising: forming a gate electrode over a substrate; consecutively forming a gate insulating layer and an active layer over the gate electrode; depositing a photoresist over the active layer and performing a photolithography process to form a first photoresist pattern, and then removing the active layer formed at a source/drain region; ashing the first photoresist pattern to expose a part of an active region; forming a source/drain electrode at the source/drain region; forming a passivation layer on the substrate including the source/drain electrode; forming a second photoresist pattern that exposes a pixel region on the passivation layer; forming a pixel region by using the second photoresist pattern as a mask; side-etching a part of the passivation layer thus to expose a part of the drain electrode; forming a pixel electrode material over the second photoresist pattern and the pixel region; and simultaneously removing the second photoresist pattern and the pixel electrode material formed thereon to form a pixel electrode.
