Abstract
A display device includes: a first semiconductor layer on a first buffer layer, and including a first active layer; a first gate insulating layer on the first semiconductor layer, and covering the first active layer; a first conductive layer on the first gate insulating layer, and including a first gate electrode; a second conductive layer on the first conductive layer, and including a first source/drain electrode; a first interlayer insulating layer on the first conductive layer; a second semiconductor layer on the first interlayer insulating layer, and including a second active layer; a second gate insulating layer on the second semiconductor layer, and covering the second active layer; and a third conductive layer on the second gate insulating layer, and including a second gate electrode and a second source/drain electrode. The first gate insulating layer and the second gate insulating layer include different insulating materials from each other.
