ABSTRACT:
A display device includes a plurality of scanning lines, a plurality of signal lines, and current-driven elements provided corresponding to portions where the scanning lines and the signal lines cross one another. The display device performs a display operating in response to the amount of a driving current supplied to the current-driven elements. The amount of the driving current is defined by the value of the driving current and the length of a period in which the driving current, which is periodically repeated, is supplied to the current-driven elements. This definition of the amount of the driving current can realize accurate gray scale control in a minute current region and a reduction in power consumption of the display device.
