Patent ID: 7525728

Claim:
A transmissive screen, comprising: a first board member on a light source side, the first board member including a Fresnel lens on a surface of the light source side and one of a vertical lenticular lens or a horizontal lenticular lens on a surface of a viewer side; and a second board member on the viewer side, the second board member including the other of the vertical lenticular lens or the horizontal lenticular lens; the first board member including a diffusing layer between the Fresnel lens and the lenticular lens on the surface of the viewer side at a position close to the Fresnel lens; wherein a relation represented by θ≧tan −1 (fp/2L) is obtained, where θ is a diffusion angle at which a distribution characteristic of diffused light passing through the diffusing layer is half the peak gain, fp is a pitch of the Fresnel lens, and L is a light path between the diffusing layer and the lenticular lens on the surface of the viewer side.
