| 摘要 | 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. | ||

| 主权项 | 1. A lens sheet, comprising a substrate and a plurality of cylindrical lenses arranged in parallel at a constant pitch on a flat surface of the substrate by having lens extending directions in parallel to each other, wherein: the cylindrical lenses neighboring to each other are isolated from each other so as not to overlap one another; and notch sections are formed at one end part of a pitch direction of each of the cylindrical lenses from the one end part of the pitch direction of each of the cylindrical lenses towards other end part of the pitch direction in such a manner that the notch sections do not reach the other end part of the pitch direction of the cylindrical lenses, and a respective length of each of the notch sections in the lens pitch direction is greater than a corresponding length of each of the notch sections in a lens extending direction. | ||
