    摘要： Optical films are disclosed that include a body having a first surface, an axis and a structured surface including a plurality of pyramidal structures. Each pyramidal structure has a rounded tip and a base including at least two first sides disposed opposite to each other and at least two second sides disposed opposite to each other. Also disclosed are optical devices including such optical films.

    摘要： Described is an optical film having a structured surface including a plurality of prismatic structures. Each prismatic structure has a base including at least two longer sides disposed opposite to each other along a first general direction and at least two shorter sides disposed opposite to each other along a second general direction. The body transmits light incident thereon along the first general direction when an angle of incidence is within a first predetermined angle range with respect to the axis and reflects light when the angle of incidence is outside the first predetermined angle range. The body transmits light incident thereon along the second general direction when an angle of incidence is within a second predetermined angle range with respect to the axis and reflects light when the angle of incidence is outside the second predetermined angle range. The optical film further includes a substrate portion having an additional optical characteristic different from an optical characteristic of the structured surface. Display devices including such optical films are also disclosed.
