Patent ID: 8031279

Claim:
An in-plane switching (IPS) mode liquid crystal display (LCD) device, comprising: first and second substrates; a gate line and a data line 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 a crossing of the gate line and the data line; at least one metal layer on a same layer of the gate line; a first storage electrode overlapping the metal layer to form a first storage capacitor; a passivation film on an entire surface of the first substrate including the switching device and the first storage electrode; a common electrode and a pixel electrode arranged an alternating pattern at an upper portion of the passivation film in the pixel region and generating an in-plane electric field, wherein at least one of the common and pixel electrodes has the first storage capacitor at its lower portion; and a liquid crystal layer between the first and second substrates.
