    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.

    Abstract: A display medium comprises: a pair of electrodes to which a voltage is applied; and a liquid crystal layer stack provided between the pair of electrodes. The liquid crystal layer stack contains a first liquid crystal layer having a first liquid crystal that undergoes transition into a specific alignment state in response to the voltage applied to the electrodes becoming equal to or greater than a first voltage value, and a second liquid crystal layer having a second liquid crystal that undergoes transition into the specific alignment state in response to the voltage becoming equal to or greater than a second voltage value. The second voltage value is greater than the first voltage value, and the second liquid crystal has a higher isotropic phase transition temperature than the first liquid crystal.
