A rear-projection screen including at least a lenticular lens sheet and a Fresnel lens sheet is configured so that the lenticular lens sheet contains, in a base material thereof made of a resin, light diffusing microparticles made of a resin having a refractive index different from a refractive index of the base material, and the light diffusing microparticles satisfy 0.5 &mgr;m&lE;&Dgr;N &times;d &lE;0.9 &mgr;m, where &Dgr;N represents a difference between a refractive index of the light diffusing microparticles and a refractive index of the base material of the lenticular lens sheet, and d represents an average particle diameter of the light diffusing microparticles. With this, a rear-projection screen with small wavelength dependency of diffusion characteristics can be provided utilizing only resins with general properties.
