An array substrate for a fringe field switching mode liquid crystal display, and the display are discussed. According to an embodiment, the array substrate includes a display area including pixel areas defined gate lines and data lines crossing the gate lines, each pixel area including a switching thin film transistor and a plate-shaped pixel electrode connected to the switching thin film transistor, the display area of the display further including a common electrode having openings in correspondence with the pixel electrodes, the common electrode being formed over the pixel electrodes throughout an entire area of the display area; and first through fourth non-display areas surrounding the display area and including pixel areas surrounding the display area, wherein each test pixel area includes a test thin film transistor and a test electrode connected to the corresponding test thin film transistor.
