A light emission drive circuit includes 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 flows 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 controls 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. A voltage control section
controls a drive voltage for operating the light emission controlling
section on the basis of a second control signal.
