Abstract
A lenticular lens sheet has arcuate-shaped warping such that the optical output lens side is the concave side, where, considering a chord B that connects points P and P3 to each other which are points on this approximate curve of arcurate shape and are of distance 150 mm from center line CL, and between which a distance is 300 mm, a distance to this chord B from the point P where this approximate curve and this center line intersect is represented by S , and, considering a chord B that connects an upper edge UE of this approximate curve to a point P 300 mm from the upper edge in the downwards direction, a distance to this chord B from the point P where the perpendicular from the central point P of this chord B intersects this approximate curve is represented by S , and, considering a chord B that connects a lower edge LE of this approximate curve to a point P 300 mm from the lower edge in the upwards direction, a distance to this chord B from the point P where the perpendicular from the central point P of this chord B intersects this approximate curve is represented by S , respectively, there exists a relationship satisfying S >S and S >S
