Abstract: A display device includes pixel circuits disposed in a display area and a driving circuit disposed in the peripheral area. The driving circuit includes a first transistor and each pixel circuit includes a second transistor. The first transistor includes a first active pattern disposed on the substrate, a first gate insulation layer having a first outer portion disposed on the first active pattern, and a first gate electrode disposed on the first gate insulation layer. The second transistor includes a second active pattern disposed on the substrate, a second gate insulation layer having a second outer portion disposed on the second active pattern, and a second gate electrode disposed on the second gate insulation layer. The first outer portion doesn't overlap the first gate electrode and has a first width. The second outer portion doesn't overlap the second gate electrode and has a second width smaller than the first width.
