Abstract:
1. An array substrate for use in an IPS-LCD device, comprising: a gate line on a substrate and disposed in a first direction; a common line on the substrate; first and second common electrodes substantially perpendicularly extending from the common line; a gate insulation layer formed on the substrate to cover the gate line, the common line and the first and second common electrodes; a data line formed on the gate insulation layer and disposed in a second direction substantially perpendicularly crossing both the gate line and the common line to define a pixel area; a pixel electrode on the gate insulation layer, the pixel electrode having first, second and third portions, wherein the first portion is disposed between the first and second common electrodes, the entire second portion is disposed over the second common electrode, and the third portion is disposed above the common line; and a thin film transistor at a crossing of the gate and data lines, the thin film transistor having a gate electrode, an active layer, a source electrode and a drain electrode, wherein the second common electrode includes a portion at a distal end, the portion being parallel to the third portion of the pixel electrode.
