Lenticular lens sheet with both a base sheet having lenticular elements and a surface diffusing part having elements of elementary shape smaller than lenticular elements

摘要

A lenticular lens sheet for use as a rear projection screen, comprises a base lenticular lens sheet having a surface provided with a plurality of lenticular elements, and a surface diffusing part having minute diffusing elements. The surface diffusing part is combined with the base lenticular lens sheet by laminating a plastic film having one surface provided with the minute diffusing elements to the base lenticular lens sheet so that the minute diffusing elements lie on the surfaces of the lenticular elements or by embossing the minute diffusing elements in the surfaces of the lenticular elements of the base lenticular lens sheet with an embossing plastic film having a surface of a shape complementary to the minute diffusing elements.
