ABSTRACT:
A lenticular lens sheet capable of reducing the color shift and improving the overall light beam transmittance. The lenticular lens sheet has an incident side lenticular lens on its light beam incident side surface and further has an emergent side lenticular lens on its emergent side surface, with peak portions of the emergent side lenticular lens being formed at substantially convergent positions of the incident side lenticular lens. When an inter-lens distance at the sheet central portion is taken to be t.sub.0 and an inter-lens distance of an end portion of an viewable area of a rear-projection screen composed of this lenticular lens sheet is taken as t.sub.1, the rate of the inter-lens distances t.sub.0 and t.sub.1 is determined to satisfy 0.98.ltoreq.t.sub.1 /t.sub.0 .ltoreq.1.10.
