PURPOSE: To solve such a problem that, when a current writing type pixel circuit is adopted in a display device, since the circuit consumes DC current at the time of driving a data line, the power consumption of the circuit at the time of writing luminance data is apt to become large. CONSTITUTION: In an active matrix type display device in which a current writing type pixel circuit 11 which has an electro-optical element whose luminance is changed by a current flowing through the element and drives the electro-optical element based on luminance information to be supplied as a current via data lines 14-1 to 14-m is arranged in a matrix shape, a current writing type pixel driving circuit 15 is made to supply a writing current whose magnitude of current is timewisely increased to respective circuits of the pixel circuits 11 via the data lines 14-1 to 14-m in the write-in cycle of the luminance information.
