Abstract
A screen device of the present invention has a light collecting element array including a plurality of light collecting elements that collect incident light from a projector and a back surface sheet. The back surface sheet includes a first electrode plate, a second electrode plate, a photoconductive layer disposed between the first electrode plate and the second electrode plate, and an image recording layer disposed between the first electrode plate and the photoconductive layer. At the back surface sheet, a light reflecting portion is formed at a light collecting region to which the light collected by the light collecting elements is irradiated, and a light absorbing portion is formed at a non-light collecting region to which the light collected by the light collecting elements is not irradiated.
