Abstract:
1. An array substrate for a fringe field switching mode liquid crystal display, the array substrate comprising: a display area including a plurality of pixel areas defined by a plurality of gate lines and a plurality of data lines crossing the plurality of 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 fringe field switching mode liquid crystal display further including a common electrode having a plurality of bar-shaped 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, wherein the first through fourth non-display areas include a plurality of test 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, and wherein each test electrode is formed at a same layer as the common electrode, is made of a same material as the common electrode, and is spaced apart from the common electrode.
