Abstract
This invention is an image display device comprising an LCD in which plural pixels are two-dimensionally arranged; a digital image processing circuit for controlling in the LCD for each pixel to display an image on the basis of image signals; a wobbling optical element, which is composed of a liquid crystal cell or a birefringence, for sequentially refracting optical paths of beams emitted from the display element to perform pixel-staggering; and a mask circuit for masking end areas in the horizontal direction, where the wobbling optical element performs pixel-staggering by a length longer than a pitch of the pixels so that pixel density is thin, so as to be displayed in black; and a control signal generator for judging whether any subject pixel is a pixel to be masked on the basis of a start signal, a vertical synchronization signal, a horizontal synchronization signal, a clock and the like. This device makes it possible that a more exact image is displayed by a limited number of pixels to be more easily watched.
