Abstract
Official abstract text for this publication.
A display device structure includes a substrate having an active region and an electrostatic protection circuit region. The first metal layer, the first insulation layer, and an amorphous silicon layer are sequentially disposed on the substrate; the first opening passes through the first insulation layer for exposing part of the first metal layer. The second metal layer, disposed on the first insulation layer or the amorphous silicon layer, fills the first opening to contact with the first metal layer; the second insulation layer and the flat layer are disposed on the second metal layer, in which the region of the flat layer overlaps the electrostatic protection circuit region. The second opening passes through the second insulation layer and the flat layer for exposing the second metal layer, in which the third metal layer fills the second opening to contact with the second metal layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device structure, comprising: a substrate comprising an active region and an electrostatic protection circuit region adjacent to the active region; a first metal layer disposed in the active region and the electrostatic protection circuit region; a first insulation layer disposed on the first metal layer in the active region and the electrostatic protection circuit region, wherein the first insulation layer has a first opening positioned in the…
