  An image display device is provided that can satisfy both transparency of a non-displaying portion and visibility of a projected image. The screen of and the image projector of the image display device are synchronized such that the image projector projects an image on a part of the screen or on the whole screen when the screen is in a light-scattering state, and projects no image when the screen is in a light-transmitting state. The screen is driven to periodically switch between a light-transmitting state and a light-scattering state at a switching frequency of 40 Hz to 100 Hz and a periodic switching duty ratio of 0.01 to 0.20.
