Patent ID: 6927814

Claim:
An array substrate for a liquid crystal display device, comprising: a substrate; a data line over the substrate in a first direction; a gate line over the substrate in a second direction perpendicular to the data line, so that the data and gate lines cross to each other to define a pixel region; a thin film transistor disposed near a crossing of the data and gate lines, the thin film transistor comprising: source and drain electrodes over the substrate; an active layer over the source and drain electrodes; an ohmic contact layer between the active layer and the source electrode and between the active layer and the drain electrode; a gate insulation layer over the active layer; and a gate electrode over the gate insulation layer; a black matrix over the thin film transistor and over the data line, the black matrix exposing a portion of the drain electrode; a color filter disposed over the substrate within the pixel region, the color filter covering a portion of the drain electrode and exposing another portion of the drain electrode; and a pixel electrode over the color filter within the pixel region, the pixel electrode contacting an exposed portion of the drain electrode.
