Abstract:
1. An array substrate for use in an IPS-LCD device, comprising: a gate line over a substrate and disposed in a first direction; a common line over the substrate and disposed in the first direction next to the gate line; a data line over the substrate and disposed in a second direction substantially perpendicularly crossing both the gate line and the common line to define a pixel region; a thin film transistor at a crossing of the gate and data lines; a pixel electrode in the pixel region, the pixel electrode having a plurality of pixel fingers and a pixel horizontal portion; and a common electrode in the pixel region, the common electrode having a plurality of common fingers extending from the common line parallel with the pixel fingers, wherein each of the common fingers has a gentle slope outline at a portion where the common finger meets the pixel finger, wherein the gentle slope outline includes a first portion, a second portion and a third portion having different slopes from one another, and wherein the first portion is at an angle with respect to the common fingers, wherein the angle is between about 70 degrees and about 90 degrees.
