1. An image display device comprising:

  • an image display portion formed of pixels disposed at pixel positions formed by crossing a plurality of data signal lines and a plurality of scan signal lines arranged in a matrix form;

    a scan signal line selection circuit that supplies a scan signal to said scan signal lines in sequence;

    a phase-expansion circuit that samples an image signal which has time-series data corresponding to each of said pixel positions in accordance with a first sampling period, converting said image signal into a plurality of phase-expanded signals including a plurality of pixel data, respectively, and outputting said phase-expanded signals in parallel, and a time-length of each of said pixel data being longer than said first sampling period;

    a plurality of sampling circuits connected to said data signal lines, respectively, each of said plurality of sampling circuits receiving one of said phase-expanded signals, samples said plurality of pixel data in a received phase-expanded signal in accordance with sampling signals having second sampling periods, and supplies sampled pixel data as a data signal to one of said data signal lines; and

    a sampling signal generator that generates said sampling signals which have said second sampling periods that are each shorter than a period corresponding to a time length of each of said pixel data in said phase-expanded signals, and that supplies said sampling signals to said plurality of sampling circuits.
