摘要： A lenticular lens comprises multiple convex unit lenses, two sides of each unit lens being curved surfaces gradually spreading outwardly from the upside (plane of emergence) to the base (plane of incidence) of the unit lens, and these unit lenses are disposed on a base film in parallel with each other. The acute angle θ between a tangent to two curves corresponding to the two sides of the unit lens on its section vertical to the longer direction and a line parallel to the upside (or the base) of the unit lens is in a range represented by the following inequality: 139(d/p)3−176(d/p)2+78(d/p)+74.4 >θ>346(d/p)3−469(d/p)2+219(d/p)+45.0 where d is the length of half of the distance between the two curves, and p is the pitch at which the unit lenses are disposed.

摘要： In a diffusion sheet 101, a plurality of approximately trapezoidal columnar unit lens portions 11 are disposed such that the long-axis directions thereof are in parallel with each other, and all the surfaces of the unit lens portions, which correspond to the long bottom segments 112 of the approximately trapezoidal sections of the unit lens portions 11 are disposed on a light-incident-side flat surface. Further, light absorbing portions 12 are disposed in the grooves between adjacent unit lens portions 11 to absorb and/or shield external light incident from a light outgoing side. In the diffusion sheet 101 arranged as described above, light incident on the unit lens portions 11 from a light incident side is totally reflected on the surfaces corresponding to the side segments 111 of the approximately trapezoidal sections vertical to the long-axis direction of the unit lens portions and outgoes from the light outgoing side. In each of the unit lens portions 11 arranged as described above, the distance h between both the bottom segments 112 and 113 of the approximately trapezoidal section is 120% or more to 400% or less of the length p of the long bottom segment 112 (h/p=1.20 to 4.00).
