Abstract:
1. An active device array substrate, having a display region and a peripheral circuit region outside the display region, the active device array substrate comprising: a substrate; a plurality of pixel units, disposed on the substrate in an array and inside the display region; a plurality of first conductive lines, disposed inside the peripheral circuit region on the substrate, the first conductive lines extending from the peripheral circuit region and being electrically connected to the pixel units; a plurality of second conductive lines, disposed inside the peripheral circuit region on the substrate, the second conductive lines extending from the peripheral circuit region and being electrically connected to the pixel units; a lead line, disposed inside the peripheral circuit region, crossing the first conductive lines thus defining two sides; at least one first electrostatic discharge (ESD) protection circuit, disposed at one side of the lead line, and electrically connected between any one of the first conductive lines and the lead line; and at least one second ESD protection circuit corresponding to the first ESD protection circuit, being disposed at the other side of the lead line, and electrically connected to the same first conductive line that the first ESD protection circuit is electrically connected to, wherein the second ESD protection circuit is electrically connected to the first ESD protection circuits via the lead line, wherein the first ESD protection circuit is electrically connected between two adjacent first conductive lines, the first ESD protection circuit comprising:
