Patent ID: 7432994

Claim:
A method of fabricating a liquid crystal display device, comprising the steps of: providing a first substrate having a display region and a non-display region around the periphery of the display region; forming at least a thin film transistor in the display region, comprising: forming a gate over the first substrate; forming an insulation layer over the first substrate to cover the gate; forming a channel layer over the insulation layer above the gate; forming a source/drain over the channel layer, forming a plurality of lead lines over the first substrate within the non-display region; wherein the process of fabricating the thin film transistor further includes forming a first shading film within the non-display region such that the first shading film is formed together with either the gate or the source/drain, and when the first shading film and the gate are formed together in a same step, the lead lines and the source/drain are also formed together on the first substrate, and the first shading film is formed over the gap between neighboring lead lines within the non-display region; providing a second substrate comprising a black matrix thereon; forming a sealant on the surface of either the first substrate or the second substrate; forming a liquid crystal layer on the surface of the substrate with the sealant; binding the first substrate and the second substrate together, wherein a space is existed between the sealant and the black matrix, and the first shading film is formed at the region where the space is located and extends to the outside of the sealant; and illuminating the sealant with light.
