Abstract
A display device includes a plurality of pixels respectively coupled to scan lines and data lines intersecting the scan lines, wherein at least some of the pixels includes a driving transistor including a substrate, a first insulating layer disposed on the substrate, a first active layer disposed on the first insulating layer, a first gate electrode disposed on the first active layer, and a first source electrode and a first drain electrode electrically connected to the first active layer, the first drain electrode being spaced apart from the first source electrode by a first distance, and a switching transistor including a second gate electrode disposed between the substrate and the first insulating layer, a second active layer disposed on the same layer as the first active layer, and a second source electrode and a second drain electrode electrically connected to the second active layer, the second drain electrode being spaced apart from the second source electrode by a second distance different from the first distance.
