Method for fabricating an array substrate for IPS mode liquid crystal display device
First Claim
1. A method for fabricating an array substrate for in-plane switching mode liquid crystal display device, comprising:
- forming a plurality of gate lines, a gate electrode, a plurality of common lines, a common electrode and a dummy line on a substrate, the dummy line being formed in a non-display area;
forming a first insulating layer over the substrate;
forming a semiconductor layer on the first insulating layer;
forming a plurality of data lines, source and drain electrodes and a pixel electrode on the semiconductor layer;
forming a second insulating layer over the substrate; and
forming an auxiliary line on the second insulating layer, the auxiliary line being overlapped with the common line and one end of the auxiliary line communicating with the dummy line.

Abstract
An array substrate for in-plane switching (IPS) mode liquid crystal display (LCD) device includes a pixel electrode having an extension portion, a vertical portion and a horizontal portion, the extension portion being extended from the drain electrode to the pixel region, the vertical portion being vertically extended from the extension portion and the horizontal portion being over the common line and being connected to the vertical portion. The device includes a common electrode having a plurality of vertical portions and a horizontal portion, the plurality of the vertical portions being vertically extended from the common line and arranged in an alternating pattern with the vertical portion of the pixel electrode, the horizontal portion connecting the plurality of the vertical portions into one. An auxiliary line is over the horizontal portion of the pixel electrode and being overlapped with the common line.
