Display substrate

摘要

A display substrate including a base substrate having a switching device, a first insulating layer over the base substrate having a contact hole partially exposing an electrode of the switching device, a first electrode over the first insulating layer, a second insulating layer over the first electrode, and a second electrode over the second insulating layer, wherein at least one of the first electrode and the second electrode is coupled to the electrode of the switching device through the contact hole, wherein at least one of the first electrode and the second electrode is formed in regions other than a peripheral region of the contact hole to prevent delamination and shorting of the pixel and common electrodes.

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.
