Patent ID: 7394510

Claim:
An array substrate device comprising: a substrate; a gate line disposed in a first direction over the substrate; a data line disposed over the substrate in a second direction, the data line perpendicularly crossing the gate line to define a pixel region; a thin film transistor near a crossing of the gate and data lines, the thin film transistor including a gate electrode, a semiconductor layer, a source electrode and a drain electrode; a capacitor electrode overlapping the gate line; a color filter having an island shaped pattern corresponding to the pixel region, the color filter exposing portions of the drain electrode and the capacitor electrode; a pixel electrode disposed over the color filter, corresponding to the pixel region and contacting the portions of the drain electrode and the capacitor electrode; a second insulating layer underneath the color filter, the second insulating layer covering the source and drain electrodes and the capacitor electrode, wherein the second insulating layer has a first drain contact hole exposing the portion of the drain electrode and a first capacitor contact hole exposing the portion of the capacitor electrode: a black matrix over the second insulating layer, the black matrix corresponding in position to the thin film transistor and the gate and data line except a portion of the gate line overlapped by the capacitor electrode; and a third insulating layer covering the black matrix and the color filter, wherein the third insulating layer has a second drain contact hole corresponding to the first drain contact hole and a second capacitor contact hole corresponding to the first capacitor contact hole, and wherein the pixel electrode is on the third insulating layer and in contact with the drain electrode through the first and second drain contact holes and with the capacitor electrode through the first and second capacitor contact holes.
