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.
