Classification: CPC H | IPC H

Claim 0:
1. A display device comprising:
a substrate;
a first conductive layer disposed on the substrate;
a first insulating layer disposed on the first conductive layer;
a second conductive layer connected to the first conductive layer through a first contact hole in the first insulating layer;
a second insulating layer filling an inside of the first contact hole; and
a third insulating layer disposed on and directly contacting the second conductive layer and the second insulating layer,
wherein the first insulating layer includes a first region that overlaps the second conductive layer and a second region that does not overlap the second conductive layer,
a top surface of the first region of the first insulating layer is positioned higher than a top surface of the second region of the first insulating layer, and
the second insulating layer does not directly contact the first insulating layer.
