Abstract

An intraframe time-division multiplexing type display device prevents prominent image defects, such as flicker, and affords a high-quality image display. A single frame of an image is displayed while changing a gray-scale level thereof by means of a number of sub-frames, each sub-frame comprising at least an address period and a sustained discharge period; further, the sub-frames have respective, mutually different sustained discharge periods. A gray-scale level adjustment unit arbitrarily sets the selection sequence of each of the number of sub-frames within an individual frame that is to be in a sustained discharge state.
