PROBLEM TO BE SOLVED: To provide a retina scanning type display which is free of a chromatic aberration and has small various aberrations and small image distortion. SOLUTION: When a video signal is inputted from outside, a video signal supply circuit 3 outputs the video signal 4, a horizontal synchronizing signal and a vertical synchronization signal. Laser light beams of three colors generated based upon the video signal 4 are synthesized and made incident on a scanning mirror 30 from a 2nd collimation optical system 18 through an optical fiber 17. Then a scanning mirror 30 scans the laser light horizontally and vertically in synchronism with the horizontal and vertical synchronization signals and the scanned laser light is made incident on a mirror surface 41a of a concave mirror 41 of a reflection optical system 40 and reflected three times between the mirror surface 41a and a mirror surface 42a of a convex mirror 42 to enter the pupil 24 of an observer at a position conjugate to a scanning mirror 42, so that the light is projected on the retina. The observer is able to recognize an image with the laser light which is scanned in two dimensions and projected on the retina. COPYRIGHT: (C)2004,JPO
