Abstract
To suppress malshaping in a lenticular lens sheet formed by using ultraviolet curing resin, which is caused due to an increase in the aspect ratio of cylindrical lenses and anisotropy of curing contraction. Notch sections are provided to the cylindrical lenses for sectioning the cylindrical lenses in a pseudo manner in the major axis direction (extending direction) of the cylindrical lenses so as to suppress the anisotropy of the curing contraction of the resin.
