Abstract:
A display device includes a pixel circuit having a driving transistor for driving a light-emitting element based on a gradation voltage held by a holding capacitor. The display device performs a first writing of gradation data using a first initialization voltage and a second writing of the gradation data using a second initialization voltage.
