1. A light emission drive circuit for supplying a light emission drive current to make a light emission element perform light emission, comprising:

  • an electric charge accumulating section for accumulating electric charges on the basis of a gradation sequence signal designating a luminance gradation sequence;

    a light emission control section for flowing a light emission drive current having a current value in accordance with an amount of the electric charges accumulated in the electric charge accumulating section;

    a writing control section for controlling a supplying state of the electric charges based on the gradation sequence signal to the electric charge accumulating section on the basis of a first control signal; and

    a voltage control section for controlling a drive voltage for operating the light emission controlling section on the basis of a second control signal.
