摘要： An IPS mode LCD device is disclosed, in which liquid crystal molecules are aligned at multiple angles in one unit pixel region to improve response speed without reducing an aperture ratio and improve transmittance-voltage characteristics. The IPS mode LCD device includes multiple gate and data lines arranged on a first substrate to cross each other to define unit pixel regions, wherein each pixel region is divided into first, second and third sub-regions. Thin film transistors are arranged at each crossing point, common lines are parallel with the gate lines, common electrodes branch from the common lines and are bent in the first, second and third sub-regions respectively at first, second and third angles. Each pixel electrode is connected to a drain electrode of each thin film transistor and arranged in parallel with the common electrodes. A liquid crystal layer is arranged between the first substrate and a second substrate opposite to the first substrate.
