Abstract: In an image projection device including a laser beam source and a diffractive optical element provided on an optical path of a laser beam L from the laser beam source, a transparent member having a refractive index higher than that of an area ahead of an emission surface on the optical path of the laser beam L and a diffractive optical element is formed on an emission surface of the transparent member. The laser beam L is obliquely incident on the diffractive optical element. The diffractive optical element generates a diffraction image in an area which is not overlapped with zeroth order light LR of the laser beam L and an area occupied by a conjugate image, and is arranged in a direction to irradiate a screen with diffracted light forming the diffraction image while substantially eliminating the zeroth order light and the diffracted light forming the conjugate image.
