ABSTRACT:
Provided is an array substrate of an LCD that includes a substrate, an active layer, a first insulating layer, and a gate electrode sequentially formed on the substrate. 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 overlies an entire surface of the substrate including the gate electrode. A pixel electrode resides on the second insulating layer. First and second contact holes reside in the first and second insulating layer and expose portions of the source region and the drain region, respectively. A portion of a source electrode contacts the source region through the first contact hole and a first portion of a drain electrode contacts the drain region and a second portion contacts the pixel electrode.
