Abstract
To suppress bad shaping generated due to fusion of neighboring cylindrical lenses in a lens sheet formed by using an ultraviolet curable resin, for example. A lens sheet includes: a substrate formed with a transparent material; a plurality of protruded lines provided on the substrate in parallel at a specific pitch; and a plurality of cylindrical lenses, each of which is provided between the plurality of protruded lines on the substrate. The protruded line for forming the lens is designed to be constituted with a set of two lines, i.e., a left protruded line and a right protruded line, to suppress fusion of the neighboring lenses.
