LENTICULAR LENS SHEET AND PROJECTION SCREEN

摘要

Provided is a lenticular lens sheet the contrast of that is high and that can improve the brightness of an image and the angle of visibility. The width A, in a corss section perpendicular to a lens element 3, of a portion 8 of connection that is created between the lens elements 3 on a light-emission side and a side wall 6 of a black stripe portion 4 is made to be 15 mu m or less. When it is assumed that P represents the pitch of the lens element 3 and H represents the width of the black stripe portion 4 as viewed in a cross section perpendicular to the lens element 3, the difference F in height between the black stripe portion 4 and the lens element 3 is set to have a range that is expressed by the inequality: 0. 098 P
