PROBLEM TO BE SOLVED: To provide an optical film.SOLUTION: The optical film includes a transparent support material and a structured layer. The structured layer is formed as aligned on the transparent support material and includes a plurality of condensing units. The condensing units have such a design that the height is varied in a longitudinal direction or a distance between prism structures is varied, which solves problems of optical defects (for example, adsorption) in the optical film and further improves optical characteristics of the optical film. |
