Patent ID: 7515237

Claim:
An in-plane switching (IPS) mode liquid crystal display(LCD) device, comprising: first and second substrates; a plurality of gate lines and data lines arranged horizontally and vertically to define a plurality of pixel regions on the first substrate; a switching device, having a gate electrode, a semiconductor layer and source and drain electrodes, at each crossing of the gate lines and the data lines; a passivation film on an entire surface of the first substrate including the switching device; a common electrode and a pixel electrode arranged in an alternating pattern at an upper portion of the passivation film, wherein the pixel electrode is connected to the drain electrode to generate an in-plane electric field between the common and pixel electrodes by an signal from the drain electrode; at least one metal layer on a same layer as the gate line; and at least one first storage electrode on a same layer as the data line and overlapping the metal layer; a liquid crystal layer between the first and second substrates, wherein the metal layer and the first storage electrode are disposed below the common electrode so that the metal layer and the first storage electrode are entirely overlapped with the common electrode.
