Patent ID: 8324111

Claim:
A method for fabricating a liquid crystal display device comprising: forming a gate electrode and a gate line on an array substrate; forming a gate insulating layer on the array substrate with the gate electrode and the gate line formed thereon; forming an active layer on the gate electrode having the gate insulating layer formed thereon, the active layer made of an amorphous zinc oxide-based semiconductor; forming an etch stopper in a shape like “H” on the active layer, the etch stopper obscuring the active layer excluding a contact region; forming source and drain electrodes on the active layer, the source and drain electrodes being electrically connected to the contact region of the active layer, and forming a data line defining a pixel region by intersecting with the gate line; forming a passivation layer on the array substrate having the source and drain electrodes and the data line formed thereon; forming a contact hole for exposing a part of the drain electrode by removing a partial region of the passivation layer; forming a pixel electrode, the pixel electrode being electrically connected to the drain electrode via the contact hole; and attaching the array substrate and a color filter substrate in a facing manner.
