Patent ID: 7852453

Claim:
A method for fabricating an in plane switching (IPS) mode liquid crystal display (LCD) device, comprising: forming a gate line, a gate electrode, a common electrode line, and a storage line over a substrate; forming a gate insulating layer on the gate line, the gate electrode, the common electrode line, and the storage line; forming a semiconductor layer, an ohmic contact layer, and a conductive layer over the gate insulating layer; forming source and drain electrodes and an active layer therebetween by etching the semiconductor layer, the ohmic contact layer and the conductive layer; forming a passivation layer over the source and drain electrodes; forming a photosensitive pattern over the passivation layer; etching the passivation layer and the gate insulating layer using the photosensitive pattern as a mask to form a first concave pattern exposing the common electrode line and a second concave pattern exposing the drain electrode; and forming a common electrode in the first concave pattern to electrically connect with the common electrode line and forming a pixel electrode in the second concave pattern to electrically connect with the drain electrode.
