Abstract
A display device includes the following elements: a semiconductor layer positioned on a substrate; a first gate insulating layer positioned on the semiconductor layer; a first gate conductive layer positioned on the first gate insulating layer; a second gate insulating layer positioned on the first gate conductive layer; a second gate conductive layer positioned on the second gate insulating layer; a first insulating layer positioned on the second gate conductive layer; a first contact hole passing through the first insulating layer, the second gate insulating layer, and the first gate insulating layer; a second contact hole passing through the first insulating layer; and a third contact hole passing through the first insulating layer and the second gate insulating layer. A cross-section of the first insulating layer in a plane perpendicular to the substrate has a curved profile.
