Abstract
A display device includes: a substrate; a light blocking layer of a driving transistor and an active layer of a switching transistor on the substrate; a buffer layer on the light blocking layer, the buffer layer overlapping the light blocking layer; an active layer of the driving transistor on the buffer layer; a first gate insulating layer on the active layer of the driving transistor and the active layer of the switching transistor; and a first gate electrode on the first gate insulating layer and overlapping the active layer of the driving transistor and a second gate electrode overlapping the active layer of the switching transistor, wherein the light blocking layer and the active layer of the switching transistor are on a same layer.
