(57) [Summary] [Problem] A double-sided lenticular that can obtain high-contrast, high-quality images without deteriorating screen characteristics such as contrast, color balance, and viewing angle characteristics even if a certain degree of optical axis shift occurs. Provide a lens sheet. SOLUTION: A large number of incident surface lenticular lenses 2 are formed in parallel on one surface of a translucent substrate 4, and an exit surface lenticular lens 1 paired with each incident surface lenticular lens 2 is arranged in parallel on the other surface. A double-sided lenticular lens sheet formed, wherein each light-emitting surface lenticular lens 2 comprises a base 11 having a substantially trapezoidal cross section and a lens portion 12 formed on an upper portion of the base, and a rising surface 13 of the base 11 is formed. A double-sided lenticular lens sheet having a tilt angle of 60 ° or more and a light absorbing layer 3 formed in a concave groove formed between adjacent light-emitting surface lenticular lenses 1. |
