PURPOSE:To enable desired brightness to be provided without any increase in power consumption by performing the luminous drive of a plasma display panel on the basis of a video signal to increase brightness signal level for a screen center position and at the same time to reduce the level for a position corresponding to the vicinity of the periphery of the screen. CONSTITUTION:A brightness signal contained in an input complex video signal is multiplied by a correction signal via a brightness signal correction circuit 20, and an image is displayed with a signal processing section 1 and a display section 2 on the basis of a complex video signal consisting of a corrected brightness signal and a synchronous signal thereby obtained. This corrected signal gives a maximum peak at the time of 1/2 vertical scanning, and a maximum peak at the time of 1/2 horizontal scanning in each horizontal scanning. Regarding image data generated in the signal processing section 1 on the basis of the complex video signal multiplied by the correction signal, therefore, high brightness appears in picture element data corresponding to a position near the center of a screen, while brightness drops all the more at a position leaving from the center of the screen.
