Abstract: In a pixel circuit composing a digital-driven organic EL display device, an organic light emitting element which emits light by the supply of electric current, and two driving transistors for controlling the supply of electric current to the organic light emitting element are connected in series. The driving transistor functions as an electric current adjustment element which adjusts an electric current flowing through the organic light emitting element. When the electric current flowing through the organic light emitting element decreases by the degradation of the organic light emitting element, decrease in temperature and the like, the driving transistor acts for increasing the electric current.
