Abstract:
1. An In-Plane Switching (IPS) mode LCD device, comprising: gate and data lines, substantially perpendicular to each other on a first substrate defining at least one unit pixel region having a transmitting part and a reflective part; a thin film transistor near a crossing of the gate and data lines; a reflective plate in the reflective part; a passivation layer on surface of the first substrate including the reflective plate; a common line substantially parallel to the gate line; a common electrode extending from the common line; a pixel electrode, substantially parallel to the common electrode; a retardation layer in the reflective part on the pixel electrode; a second substrate opposite to the first substrate; a liquid crystal layer between the first and second substrates; and first and second polarizing sheets on outer surfaces of the first and second substrates respectively, wherein a cell gap in the reflective part is substantially the same as a cell gap in the transmitting part, wherein an interval between the common and pixel electrodes in the reflective part is greater than an interval between the common and pixel electrodes in the transmitting part.
