Patent ID: 6856371

Claim:
An In Plane-Fringe Field Switching (“IP-FFS”) mode Liquid Crystal Device (“LCD”) comprising: a transparent insulating substrate; a plurality of gate bus lines and data bus lines cross-arranged on the substrate defining a plurality of unit pixels; at least one common bus line arranged on a central part of each of the unit pixels, being parallel with the gate bus lines; for each unit pixel, a thin film transistor arranged at the intersection of the gate bus line and the data bus line; a counter electrode arranged in each unit pixel, including a first body arranged on the edge of one side of each unit pixel to be parallel with the data bus line and having a plurality of first branches, a gate insulating layer and a protective layer disposed over the first body, the end of each first branch being in contact with the first body through a contact hole passing through the gate insulating layer and the protective layer disposed over the first body, and the other end of each first branch extending away from the first body toward the other edge of the unit pixel, wherein the first branches are made of ITO and are arranged having a predetermined angle symmetric with respect to the common bus line; and a pixel electrode arranged in each unit pixel to be in contact with the thin film transistor, including a second body arranged on the other edge of the unit pixel at the opposite edge of the unit pixel from the first body, the protective layer disposed over the second body, the second body being located on the gate insulating layer and under the other ends of the first branches, the second body being parallel with the data bus line and having a plurality of second branches, one end of each second branch being in contact with the second body through a contact hole passing through the protective layer disposed over the second body and the other end of each second branch extending to a location above the first body, wherein the second branches are made of ITO and are arranged on the same layer with the first branches, so that the second branches are disposed between and oriented parallel to the first branches.
