Abstract
An optical light redirecting film that can be made by microreplication, and that is suitable for use in an autostereoscopic backlight or display, includes opposed first and second structured surfaces. The first structured surface includes lenticular features and the second structured surface includes prismatic features. In some cases, at least a first prismatic feature has a first prism optical axis that is tilted relative to a thickness axis of the film perpendicular to the film plane. In some cases, at least a first lenticular feature has a first lenticular optical axis that is tilted relative to the thickness axis. In some cases, the film may have a central film caliper (thickness) at a central portion of the film and an edge film caliper at a first edge portion of the film, the central film caliper being greater than the edge film caliper.
