ABSTRACT:
The present invention is related to an IPS-LCD device and a method of fabricating an array substrate for use in the IPS-LCD device, which increase a high aperture ratio and provide a large and enough storage capacitance. A common line formed of an opaque metal is designed to have a small width for the increased aperture ratio. A portion of a pixel electrode overlaps one of common electrodes, thereby forming a supplementary storage capacitor. As a result, with a main storage capacitor comprised of a portion of pixel electrode and a portion of common line, the array substrate of the present invention can have two storage capacitors. A sufficient and satisfactory capacitance can be obtained and the aperture ratio is raised.
