Abstract
An image display system produces a color image by arranging a color shutter capable of time-divisionally switching a plurality of colors to be displayed, in front of a monochrome image display. This image display system comprises: a self-luminous image display part for time-divisionally displaying monochrome images corresponding to three primary colors; and a color display part for time-divisionally coloring and outputting the monochrome images which formed on the side of the light outgoing surface of the self-luminous image display part and which correspond to the three primary colors. The color display part further comprises: a liquid crystal cell driven by carrying out an optical switching on the basis of the inversion between positive and negative polarities; a transparent electrode formed by dividing the liquid crystal cell into a plurality of parts; and a liquid crystal color shutter capable of optionally setting display colors for a plurality of display regions by means of the transparent electrode, the liquid crystal color shutter displaying different display colors for at least two display regions in an optional time in a driving condition.
