The present invention consists in a rear image projection apparatus having a transmissive screen of high efficiency and low moiré disturbance. In particular, the screen comprises a Fresnel sheet having a Fresnel lens, a front sheet having a horizontally-diffusing lenticular lens and a light diffusing element, and if necessary, a third sheet, wherein at least one surface of the Fresnel sheet or the third sheet is formed with a vertically-diffusing lenticular lens, and a pitch of the Fresnel lens is set to be at most 150% of an effective diffusion width of the diffusion element. |
