Abstract

PURPOSE:To enable mass production of the captioned screen sheet free from deformation like warpage, etc. and uniform in thickness by tranferring a screen member and light-diffusive film on the parallel zone between an upper and a lower metallic belt affording a sufficient period of time and under pressure. CONSTITUTION:A reverse type mold 6 of a lenticular mold is provided on the surface of an upper stainless belt 1, and the stainless belts 1, 2 are turned in the direction of the arrow. The screen material 7 under a softened state is supplied from an extrusion molding machine 8 to the parallel zone while the light diffusive film 9 is supplied to the lower surface and fed under pressure. A screen sheet 11 having a light diffusion layer 13 laminated on the back side of a lenticular lens 12 can be obtained in good reproducibility.
