An image display device includes a light source, a screen, an optical system, a converging lens, an optical distance correction member, and a scanning unit. The converging lens is configured to converge the light emitted from the light source onto the screen. The optical distance correction member is disposed between the converging lens and the screen. The scanning unit scans the screen with the light from the light source. The screen is disposed so as to be inclined with respect to a plane perpendicular to an optical axis of the converging lens so that a viewing distance of the virtual image gradually varies. The optical distance correction member adjusts an optical distance of light transmitting through the optical distance correction member so that a distance between the screen and a focusing position of the light is made substantially identical over an entire image display region in the screen.
