Abstract
A display device includes a pixel region having a plurality of pixel and a driver circuit outside the pixel region. The pixels have a driving transistor and a switching transistor having a gate and a pair of terminals, a light-emitting element having an input terminal, and a storage capacitor having a pair of terminals. One terminal of the switching transistor is electrically connected to the gate of the driving transistor and one terminal of the storage capacitor. One terminal of the driving transistor is electrically connected to the other terminal of the storage capacitor and the input terminal. The driver circuit includes first and second transistors having a gate and a pair of terminal. The other terminal of the switching transistor is electrically connected to one terminal of the first transistor and one terminal of the second transistor. The second transistor has a channel region including an oxide semiconductor.
