Patent ID: 7989147

Claim:
A method for fabricating a liquid crystal display device comprising: providing a first substrate having a pixel portion and a pad portion; sequentially laminating a gate insulating layer, a semiconductor layer, a conductive layer and a photoresist film on the first substrate where a gate electrode is patterned; forming a photoresist film pattern by patterning the photoresist film using a half-tone mask; patterning the conductive layer and the semiconductor layer using the photoresist film pattern as a mask; partially removing the photoresist film pattern through a pre-ashing process; forming source/drain electrodes by patterning the conductive layer using the remnant photoresist film pattern as a mask; forming a passivation layer and a pixel electrode on the first substrate; attaching a second substrate to the first substrate; and forming a liquid crystal layer between the first substrate and the second substrate.
