Abstract
To display an image and the back side image in an overlapped state on a screen, with good visibility and see-through capability. The screen scanned with an image light from the projector has an optical layer and a plurality of control electrodes which are arranged side by side along the optical layer. The synchronous controller applies a voltage to the plurality of control electrodes, and, in a scanning period T of the image light, switches the optical state of the screen by the unit of the segmented region, between the visual state and the nonvisual state. The synchronous controller, in the period T, switches the optical state of a plurality of segmented regionsin synchronous with the scanning period of the image light, maintains the optical state of a projected region of the screen in the visual state by a voltage with two or more amplitudes.
