Patent abstract
There are provided a lens sheet for a screen, which is highly stable by virtue of a reduced tendency toward warping, lifting and the like of the lens caused by external humidity and, at the same time, has a suppressed tendency toward friction between lenses during transport as a screen, and a resin composition for constituting the lens sheet. The lens sheet is used in combination with other lens sheet and comprises one or at least two layers. When the layer in contact with the above other lens is formed of a thermoplastic resin, the universal hardness of the thermoplastic resin composition is brought to a range of 31.0 to 42.0 N/mm2.
