Abstract:
A liquid crystal display device comprising:a substrate;a gate electrode on the substrate;a first insulating lays on the substrate and the gate electrode;an active layer on the first insulating layer;a second insulating layer on the active layer over the gate electrode and having approximately the same width as the gate electrode;a silicide layer directly on the active layer and having first and second sides relative to the second insulating layer on an exposed surface of the active layer, the first and second sides of the silicide layer acting as source and drain electrodes, respectively;a metal patter only on the second side of the silicide layer;a pixel electrode on the first side of the silicide layer; anda third insulating layer over the second side of the silicide layer, a portion of the third insulating layer covering the second insulating layer,wherein the silicide layer is formed by reacting a metal material with a material of the active layer,wherein data line is formed from the metal pattern by selectively removing any reacted portion of the metal pattern on the first side of the silicide layer, andwherein any unreacted material of the metal pattern on the second insulating layer and the first insulating layer next to the first side of the silicide layer is selectively removed.
