ABSTRACT:
The 2-D/3-D compatible type image display according to the present invention is constructed by arranging a liquid crystal panel which is a display panel, a dispersed type liquid crystal panel which is a diffusing effect on/off panel, a light separating means, a backlight which is a plane light source, so as to be nearer to an observer in this order. It is possible by processing the image signal supplied to the liquid crystal panel to form a first group of pixels lined in longitudinal direction of a picture and a second group of pixels lined in the same direction of the picture alternately formed in horizontal direction, and to make the first group of pixels and the second group of pixels have different observing points respectively as left eye pixels and right eye pixels (when 3-D images are displayed), or to make the first group of pixels and the second group of pixels have the same observing points with each other (when 2-D images are displayed). When 3-D images are displayed, light from the light separating means is transmitted by making diffusing effect off. When 2-D images are displayed, light from the light separating means is diffused by making diffusing effect on.
