ARRAY SUBSTRATE, DISPLAY DEVICE HAVING THE SAME, AND METHOD FOR PROTECTING DISPLAY AREA OF ARRAY SUBSTRATE FROM STATIC ELECTRICITY

摘要

PROBLEM TO BE SOLVED: To provide an array substrate capable of preventing a defect due to static electricity flowing in a manufacturing process, to provide a display device having the same and to provide a method of protecting a display area of the array substrate from static electricity. SOLUTION: The array substrate includes: a base substrate formed in a display area in which a plurality of pixel portions are formed and a peripheral area enclosing the display area; a dummy circuit section which is formed in a peripheral area and protects the pixel portions from static electricity; an extended line which is extended from the dummy circuit section and formed with a first metal layer in the peripheral area; a metal pattern formed with a second metal layer in the peripheral area and transmitting common voltage; and an overlap portion where the extended line and the metal pattern are overlapped with each other.
