Abstract: Light control films are provided that confine light transmitted therethrough to be within a 360° view region and block light outside of this view region. The light control films can provide security in all directions including right-and-left and up-and-down of the films, without compromising light transmittance compared to one-dimensional light control films. The light control films include an array of light transmissive, tapered posts and absorptive regions disposed between the posts.
