Patent ID: 7638801

Claim:
A liquid crystal display device, comprising: first and second substrates; an active layer on the first substrate; a first insulation layer on the first substrate; a gate electrode, a gate line and a pixel electrode on the first insulation layer through a single photography process using a slit exposure, the gate electrode and the gate line having a first conductive layer and a second conductive layer and the pixel electrode having the first conductive layer, wherein the first conductive layer is formed of transparent conductive material and the second conductive layer is formed of opaque conductive material; a second insulation layer on the first substrate, the second insulation layer having a contact hole; a source electrode and a drain electrode on the first substrate, the source electrode being connected with a source region through the contact hole and the drain electrode being connected with a drain region and being directly connected with a surface of the pixel electrode without a contact hole, wherein an upper portion of an edge of the pixel electrode extends directly under the second insulation layer and is in contact with the second insulation layer; and a liquid crystal layer between the first and second substrates.
