PROBLEM TO BE SOLVED: To provide an image projection device which achieves a thinner shape and space saving and can obtain an optimum image with high resolution feeling and little screen distortion on a large image screen.SOLUTION: The image projection device includes: an optical engine 5 which projects image light; an aspheric mirror 3 which reflects the image light projected by the optical engine 5 on a reflection surface having a rotation asymmetric shape around the optical axis as the center; a reflective screen 1 which projects the image light reflected by the aspheric mirror 3; a shield chassis 6 which houses the optical engine 5, the aspheric mirror 3 and an electric circuit part 9 for electrically driving the optical engine 5; and a support member 7 which connects a back part of the shield chassis 9 to a back part of the reflective screen 1 in a positioned state. |
