PURPOSE: An optical film is provided to vary straight line penetration ratio of incident light according incidence angle. CONSTITUTION: A convex part(14a) parallelly arranges a photosensitive laminated body(10) on a lenticular lens(14) which is arranged lengthwise. The photosensitive laminated body comprises a dimorphism PET or a mask(18), a photo curing resin layer, and a transparent PET. UV parallel rays(12) are radiated from a normal direction of lenticular(14) toward the lenticular lens. The UV parallel rays pass through the lenticular lens and light(16) is diffused in a Y-direction from the convex part of the lenticular and the light is radiated to the photosensitive laminated body. The light is widely diffused in one direction through the lenticular lens and the light is narrowly diffused in a direction which is at right angles the one direction. The photosensitive laminated body is hardened when the light is radiated and forms a curable resin layer having an internal structure. [Reference numerals] (AA) X-direction; (BB) Y-direction |
