Patent ID: 8790941

Claim:
A method of manufacturing an array substrate for a fringe field switching mode liquid crystal display device, comprising: forming a gate line, a gate electrode and a pixel electrode on a substrate including a pixel region defined thereon, the pixel electrode disposed in the pixel region; forming a gate insulating layer on the gate line, the gate electrode and the pixel electrode; forming a data line, a source electrode, a drain electrode, and a semiconductor layer on the gate insulating layer, the data line crossing the gate line to define the pixel region, the semiconductor layer disposed over the gate electrode, the source electrode and the drain electrode spaced apart from each other over the semiconductor layer, the drain electrode overlapping the pixel electrode; forming a passivation layer on the data line, the source electrode and the drain electrode; forming a contact hole exposing a top surface and a side surface of the drain electrode and the pixel electrode by patterning the passivation layer and the gate insulating layer; and forming a common electrode and a connection pattern on the passivation layer, wherein the common electrode includes bar-shaped openings in the pixel region and a hole corresponding to the contact hole, and wherein the connection pattern is disposed in the hole, is spaced apart from the common electrode and directly contacts the top surface and side surface of the drain electrode and the pixel electrode.
