Abstract
When one row electrode has been selected with a selection signal, driving signals are supplied to column electrodes so as to cause electroluminescence elements at corresponding display pixels to emit light. The driving period for impressing the driving signals and emitting light from the corresponding display pixels is determined on the basis of the color of the display pixel that is to emit light. Thus, with a simple configuration, the brightness of each color can be made uniform without the use of pulse width modulation or the like.
