  • Patent number: 9377636
    Abstract: An array substrate includes a base substrate, a plurality of storage voltage lines, a plurality of connecting lines, and a common voltage applying section. Pixels are formed in regions defined by a plurality of gate lines extending along a first direction and data lines extending along a second direction. The connecting lines are connected to the storage voltage lines that are formed on adjacent pixels of pixels arranged in the second direction. The common voltage applying section applies a common voltage to the storage voltage lines that are formed in a portion of the pixels arranged in the first direction. Thus, a substantially uniform current may be applied to the display area to decrease the distortion of the common voltage, thereby increasing a liquid crystal display device's display quality.
