1. A display apparatus, comprising:

  • an optical modulation device including a plurality of pixels and a pair of electrodes to which a voltage is applied, an illumination device for illuminating said optical modulation device instantaneously and successively with a plurality of monochromatic lights of different colors in a prescribed period to provide a full-color image in combination with application of the voltage to the electrodes of said optical modulation device thereby effecting a full-color display over a succession of the prescribed period, and control means for dividing each prescribed period into two periods including a first period for displaying a full-color image at each pixel and a second period immediately after the first period and for placing the optical modulation device in a non-display state, wherein the second period is longer than a period from termination of illumination with a monochromatic light to initiation of illumination with a subsequent monochromatic light within the first period.
