An image display device includes: a light source; a screen on which an image is formed when light from the light source is applied thereto; an optical system configured to generate a virtual image by light from the screen; an actuator configured to move the screen in an optical axis direction; a position detector configured to detect a movement position of the screen; a servo circuit configured to cause the movement of the screen by the actuator to follow a target waveform on the basis of a signal from the position detector; and a correction circuit configured to reduce a deviation between a timing to move the screen by the servo circuit and a timing to form the image on the screen.
