ABSTRACT:
An array substrate includes a base substrate, a dummy circuit section, a dummy pixel portion, an extended line, a common voltage line, and an overlap portion. Pixel portions are formed in a display area. The dummy circuit section is formed in a peripheral area to protect the pixel portions from static electricity. The dummy pixel portion is adjacent to the dummy circuit section. The dummy circuit section is in an electrically floating state. The extended line is extended from the dummy circuit section and electrically open with respect to the dummy pixel portion. The common voltage line is overlapped with the extended line of the dummy circuit section, the extended line being electrically open with respect to the display area, and thus the display area may be protected from the static electricity which flows into the dummy circuit section.
