Abstract:
1. An active matrix substrate, comprising: a substrate having an active region and a peripheral region, wherein the peripheral region and the active region are disposed adjacent to each other; a plurality of pixel units arranged to form a matrix within the active region of the substrate; a plurality of driving lines disposed in the active region and the peripheral region and are electrically connected to the pixel units; an electrostatic discharge protection circuit disposed on the substrate within the peripheral region, wherein the electrostatic discharge protection circuit is electrically connected to the pixel units, and the electrostatic discharge protection circuit further comprises: a first conductive line; a second conductive line disposed between the pixel units and the first conductive line; a plurality of sets of first protective elements disposed between the first conductive line and the second conductive line, wherein each set of first protective elements is connected to a corresponding driving line; and a set of second protective elements disposed adjacent to the outermost driving line, wherein the set of second protective elements are connected to the first conductive line and the second conductive line.
