Abstract: A screen including a light control sheet which includes a front surface and a rear surface and has a transparent state and an opaque state, and a transparent reflective layer that faces the rear surface. The front surface is positioned such that light from a projection device is applied in the opaque state. The opaque state includes a state in which an average diffuse reflectance of visible light applied to the front surface is 10% or more and less than 20%.

Abstract: A light control sheet including a light control sheet body having a front surface and a back surface, the light control sheet body including a first film including a transparent electrode layer, a second film including a transparent electrode layer, a liquid crystal layer formed between the first and second films, and a sealant covering an edge portion of the liquid crystal layer. The second film has a second film contact surface which includes a portion in contact with the liquid crystal layer, and further includes a second film outer peripheral part on which the sealant is formed, the second film outer peripheral part is extended along the edge portion of the liquid crystal layer, and when viewed in a first direction from the front surface to the back surface, the second film outer peripheral part does not overlap the first film or the liquid crystal layer.
