Claim Text:
1. An active-matrix display device comprising: a plurality of video signal lines configured to transmit signals representing an image to be displayed; a plurality of scanning signal lines crossing the video signal lines; a plurality of pixel circuits arranged in a matrix corresponding to intersections of the video signal lines and the scanning signal lines, to display a plurality of pixels forming the image to be displayed; a power line for providing a power supply voltage to the pixel circuits; a scanning signal line driver circuit configured to selectively drive the scanning signal lines; a frame memory configured to store externally provided display data signals for one frame and to sequentially output the stored display data signals for one frame as previous frame display data; a tone voltage generation portion configured to generate a plurality of tone voltages on the basis of reference voltages for voltages to be applied to the video signal lines, wherein the tone voltage generation portion comprises: a video signal line driver circuit configured to generate the signals representing the image to be displayed by respectively selecting tone voltages for the plurality of video signal lines from among the plurality of tone voltages based on the previous frame display data, and configured to drive the video signal lines by applying the signals representing the image to be displayed; and a power supply circuit configured to provide a power supply voltage to the power line, wherein
