1. A light control film, comprising:
a light input surface and a light output surface opposite the light input surface;
alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions have an aspect ratio of at least 30 and the light control film has a relative transmission of at least 75% at a viewing angle orthogonal to the light input surface, wherein the aspect ratio of the absorptive regions is calculated by dividing the height of the absorptive region by the maximum width of the absorptive region, wherein the transmissive regions and the absorptive regions are joined by a continuous land layer, and wherein each absorptive region has a width nearest the continuous land layer that is less than an average width of the absorptive region.
