ABSTRACT:
The present disclosure is directed to optical films having a first surface and a structured surface, the structured surface comprising a plurality of prismatic structures. Each prismatic structure has a base including at least two first sides and at least two second sides. At least one of the first and second sides of at least one of the plurality of prismatic structures is offset with respect to at least one of the first and second sides of at least one other prismatic structure.
