Abstract:
1. An active device array substrate, having a display area and a peripheral area outside the display area, comprising: a substrate; a plurality of pixel units, disposed in the display area; a plurality of first lead wires, disposed in the peripheral area of the substrate, and electrically connected to the pixel units, wherein each of the first lead wires has two opposite first tips being separated apart from each other for a first interval; an insulating layer, covering the first lead wires, and having at least a first opening for exposing top surfaces of the two opposite first tips, wherein a covering scope of the first opening is greater than that of the first interval; a first filler, filling the first opening and covering the top surfaces and sidewalls of the two opposite first tips exposed by the insulating layer, the dielectric constant of the first filler being smaller than that of the insulating layer, wherein the material of the first filler comprises an organic insulating material, benzocyclobutene, or silicon oxide; a plurality of second lead wires, disposed in the peripheral area and electrically connected to the pixel units; and a passivation layer, covering the second lead wires, wherein the second lead wires are located between the insulating layer and the passivation layer.
