A light control film includes a plurality of spaced apart substantially parallel first light absorbing regions arranged along a first direction, each first light absorbing region having a width and a height, the plurality of first light absorbing regions including nonoverlapping first and second sub-pluralities of the plurality of first light absorbing regions, the first sub-plurality of the plurality of first light absorbing regions having a first viewing angle, the second sub-plurality of the plurality of first light absorbing regions having a different second viewing angle.
A light control film comprising alternating light absorbing and light transmissive regions disposed between, and substantially perpendicular to, substantially parallel opposing major first and second surfaces, each light absorbing region tapering from a wider first end proximate the major first surface to a narrower second end proximate the major second surface, each light transmissive region terminating at, and aligned with, a corresponding optical lens at the major first surface, each light absorbing region partially filled with a light absorbing material so that the first end of each light absorbing region is recessed on each lateral side of the light absorbing region relative to a base of the optical lens on each lateral side of the light absorbing region and concave toward the major first surface.
