Abstract:
In a case where a p-channel thin film transistor is used as a thin film transistor that is electrically connected to a light-emitting element and drives the light-emitting element, a value of cutoff current of the p-channel thin film transistor is made lower than that of a p-channel thin film transistor of a driver circuit. Specifically, channel doping is selectively performed on a semiconductor layer of a thin film transistor included in a pixel.
