Abstract:
1. A display substrate, comprising: a base substrate including a switching device including an electrode; a gate insulating layer in direct physical contact with the base substrate; a first insulating layer arranged over and in direct physical contact with the gate insulating layer, said first insulating layer being perforated by a contact hole exposing the electrode of the switching device; a first electrode arranged over and in direct physical contact with the first insulating layer; a second insulating layer arranged over and in direct physical contact with the first electrode; and a second electrode arranged over and in direct physical contact with the second insulating layer, wherein the first electrode is coupled to the electrode of the switching device via the contact hole, and solely a portion of either the first electrode or the second electrode is over a surface area of a peripheral region of the contact hole and the first electrode and the second electrode stacked on the base substrate.
