Abstract
A display device includes a first electrode, a second electrode, an organic light emitting layer, a first transistor, and a second transistor. The first transistor includes a first semiconductor layer, a first conductive unit, a second conductive unit, a first gate electrode, and a first gate insulating film. The second transistor includes a second semiconductor layer, a third conductive unit, a fourth conductive unit, a second gate electrode, and a second gate insulating film. An amount of hydrogen included in the first gate insulating film is larger than an amount of hydrogen included in the second gate insulating film.
