| description | PROBLEM TO BE SOLVED: To provide a transmission type screen apparatus with less deterioration of performance due to a change in humidity, capable of securing the flatness of a fresnel lens sheet required to project a high-definition image on a screen, and also, capable of facilitating the control and handling of the lens sheet. SOLUTION: The transmission type screen apparatus includes the fresnel lens sheet 1 and a lenticular lens sheet 3, and the apparatus is constituted of at least two sheet members. The fresnel lens sheet 1 as a glass plate 4 obtained by optically sticking a fresnel lens film 5 on an incident surface is used as the incident side sheet of the screen apparatus, and a light-transmissive synthetic rein plate 7 obtained by optically sticking a moisture-proof film 6 constituted of light-transmissive material having low moisture transmittance on an exit surface is used as the exit side sheet of the screen apparatus.
