Abstract:
1. An array substrate for an IPS mode LCD device, comprising: a substrate; a gate line along a first direction; a data line along a second direction; a TFT connected to the gate and data lines; a common electrode having a plate shape on the substrate and comprised of a first transparent conductive material; first and second metal patterns disposed between the common electrode and the data line; a pixel electrode comprised of a second transparent conductive material on the common electrode and including first and second portions and a plurality of third portions combining the first portion with the second portion, wherein the first and second portions are parallel to the second direction and separated from each other, and wherein the plurality of third portions are oblique to the first and second portions and separated from one another; and an insulating layer between the common and pixel electrodes, wherein the insulating layer has a dielectric constant between about 3 and about 4 and includes one of SiO2, benzocyclobutene (BCB) and acrylic resin.
