ABSTRACT:
A scan-type image display device which displays an image by scan of laser beam emitted from a light source in one direction and another direction of a light receiving surface includes: a first scan unit which performs scan of the laser beam in the one direction by deflecting the laser beam; a second scan unit which performs scan of the laser beam in the another direction by deflecting the laser beam; and a scan control unit which equalizes the scan width of the laser beam scan in the one direction by using the first scan unit performed at each position in the another direction within the light receiving surface.
