Abstract:
An image display device comprising:a display element including a plurality of two-dimensionally arranged pixels; image processing means for controlling in the display element for each pixel to display an image on the basis of image signals; optical path changing means for sequentially refracting optical paths of beams emitted from the display element to perform pixel-staggering; and mask means for displaying at least one of end areas in the horizontal direction and end areas in the vertical direction in black when pixel-staggering is performed by the optical path changing means; wherein the optical path changing means is for performing the pixel-staggering by shifting apparent positions of the pixels, by a length longer than the pitch between the pixels, in at least one direction of the horizontal direction and the vertical direction; and the mask means is for displaying, in black, both end areas in the direction along which the apparent positions of the pixels are shifted by the length longer than the pitch between the pixels.
