Claim:
A lens sheet for a screen comprising at least one layer, adapted for use in combination with another lens sheet, wherein the layer in contact with said another lens sheet is formed of a thermoplastic resin, said thermoplastic resin having a universal hardness of 31.0 to 42.0 N/mm 2 , wherein, when the lens sheet for a screen has a single-layer structure, said thermoplastic resin has a water absorption of not more than 0.2%, and when the lens sheet for a screen comprises two or more layers, a relationship represented by α 1 −α 2 >0.1% is satisfied, where α 1 represents the water absorption % of the thermoplastic resin constituting the layer in contact with said another lens sheet, and α2 represents the water absorption % of the resin constituting the remaining layer(s).
