Patent ID: 7528924

Claim:
A method for fabricating a liquid crystal display comprising: forming a first substrate part having a gate line, a data line, a common voltage terminal, a contact area connected to the common voltage terminal, a thin film transistor and a pixel electrode, the contact area being provided at an edge portion of the first substrate part; forming a second substrate part having a common electrode; attaching the first and second substrate parts to each other to form attached substrates; exposing the contact area at the edge of the first substrate part of the attached substrates; and electrically connecting the contact area of the first substrate part to the common electrode of the second substrate part, wherein forming the first substrate comprises: forming a gate electrode and a gate line in a first direction on a substrate; forming a first insulating layer over the substrate; forming an active layer and an ohmic contact layer at a region on the insulating layer, the region corresponding to an area above the gate electrode; forming source and drain electrodes on the ohmic contact layer and a data line in a second direction normal to the first direction; forming a pixel electrode at least partially overlapped with and electrically connected with the drain electrode; and forming a second insulating layer over the substrate including the pixel electrode, wherein only three masks are used to form the gate electrode, the first insulating layer, the active layer, the ohmic contact layer, the source and drain electrodes, the pixel electrode and the second insulating layer.
