1. An image display device comprising:
an image projection unit that projects image display light; an intermediate image formation unit that forms a real image that is based on the image display light projected from the image projection unit; and a projection mirror that reflects, toward a virtual image presenting surface, the image display light that has passed through the intermediate image formation unit; wherein the intermediate image formation unit includes: a concave lens that controls the direction of the image display light that has passed through; and a diffusion screen that controls the light distribution angle of the image display light, wherein, in the diffusion screen, two light diffusion plates that have respective flat surfaces and respective light diffusion surfaces that face the respective flat surfaces and diffuse and transmit incident light are layered such that the respective light diffusion surfaces face each other, and wherein the light diffusion surfaces diffuse light that is incident on the respective light diffusion surfaces in substantially the same light distribution. |
