Patent ID: 8253918

Claim:
A method of manufacturing an array substrate for an in-plane switching mode liquid crystal display device, comprising: forming a gate line, a gate electrode and a common line on a substrate, the gate line extending along a first direction, the gate electrode connected to the gate line, and the common line disposed between adjacent gate lines; forming an active layer and an ohmic contact layer over the gate electrode; forming a data line, a source electrode and a drain electrode on the ohmic contact layer, the data line extending along a second direction and crossing the gate line to define a pixel region, the source electrode connected to the data line, and the drain electrode spaced apart from the source electrode; forming a passivation layer covering the data line, the source electrode and the drain electrode, the passivation layer including a first contact hole exposing the drain electrode and at least one second contact hole exposing the common line; and forming a pixel electrode and a common electrode on the passivation layer, the pixel electrode including horizontal parts along the first direction, and the common electrode including horizontal portions along the first direction, wherein the pixel electrode further includes a portion directly connected to one of the horizontal parts, wherein the portion overlaps and contacts the drain electrode through a contact hole, wherein the portion overlaps the gate line.
