Abstract

Official abstract text for this publication.

A method for manufacturing a display device includes forming a first gate metal wire on a substrate, forming a first insulation layer that covers the first gate metal wire, forming a second gate metal wire on the first insulation layer, forming a second main insulation layer that covers the second gate metal wire, forming a second auxiliary insulation layer on the second main insulation layer, forming an exposed portion of an upper surface of the second main insulation layer by polishing the second auxiliary insulation layer, and forming a first data metal wire on the second main insulation layer and the second auxiliary insulation layer.

First claim

Opening claim text (preview).

What is claimed is: 1. A display device, comprising: a substrate; a first gate metal wire that is disposed on the substrate; a first insulation layer that covers the first gate metal wire; a second gate metal wire that is disposed on the first insulation layer; a second main insulation layer that covers the second gate metal wire; a second auxiliary insulation layer that is disposed on the second main insulation layer; and a first data metal wire that is disposed on the second main insulation layer and the second auxiliary insulation layer, wherein: an upper surface of the second auxiliary insulation layer is disposed on the same horizontal plane as a part of an upper surface of the second main insulation layer, the uppermost layer of the second main insulation layer includes a silicon nitride, and the second auxiliary insulation layer includes a silicon oxide. 2. The display device as claimed in claim 1 , further comprising: a third main insulation layer that covers the first data metal wire; a third auxiliary insulation layer that is disposed on the third main insulation layer; and a second data metal wire that is disposed on the third main insulation layer and the third auxiliary insulation layer, wherein: an upper surface of the third auxiliary insulation layer is disposed on the same horizontal plane as a part of an upper surface of the third main insulation layer, and the third main insulation layer includes a silicon nitride. 3. The display device as claimed in claim 2 , wherein a part of the upper surface of the third main insulation layer that is disposed between the first data metal wire and the second data metal wire directly contacts the second data metal wire. 4. The display device as claimed in claim 3 , wherein a thickness of the third main insulation layer is smaller than a thickness of the second main insulation layer.
