Patent ID: 7368755

Claim:
An array substrate of an LCD comprising: a substrate; an active layer on the substrate, a first insulating layer overlying the active layer, and a gate electrode overlying the first insulating layer; a source region and a drain region reside in predetermined regions of the active layer and each is doped with impurity ions; a second insulating layer overlying an entire surface of the substrate including the gate electrode, the second insulating layer contacting the gate electrode; a pixel electrode contacting the second insulating layer; first and second contact holes in the first and second insulating layer and exposing portions of the source region and the drain regions, respectively; a source electrode of which a portion contacts the source region through the first contact hole; a drain electrode of which a first portion contacts the drain region and a second portion contacts an upper face of the pixel electrode; and a third insulating layer formed on the source electrode, the drain electrode and the pixel electrode.
