Abstract
A display device includes a light-emitting element; a first transistor that transmits a driving current to the light-emitting element; and a second transistor that transmits a data signal to the first transistor. The first transistor includes a first active layer, the second transistor includes a second active layer including an oxide semiconductor, and the light-emitting element includes a first conductivity type semiconductor having a first polarity, a second conductivity-type semiconductor having a second polarity different from the first polarity, and an active layer arranged between the first conductivity type semiconductor and the second conductivity-type semiconductor.
