Abstract:
Image display device includes; light source; screen on which an image is drawn by being scanned two-dimensionally by laser light; scanner that causes the laser light to scan the screen; mirror drive circuit that chives scanner; and an optical system that generates a virtual image of the image drawn on screen. On screen, there are arranged a plurality of lens regions so as to be arranged individually in a first direction and a second direction perpendicular to the first direction, and mirror drive circuit sets a plurality of scan lines such that a pitch of the scan lines can become smaller than a pitch of lens regions in the second direction.
