Abstract
An optical component includes a substrate and a plurality of structures formed on a first major surface of the substrate and extending from the first major surface along a thickness direction of the optical component. The optical component can be assembled with another optical component to form a light control film. A light control film includes first and second optical components including respective pluralities of first and second structures formed on, and extending from, respective first and second substrates. The first and second optical components are assembled so that the first and second structures are disposed between the first and second substrates and interleaved to form a plurality of pairs of adjacent first and second structures. For each of at least some of the pairs, the adjacent first and second structures define an optical cavity therebetween substantially filled with a light absorbing material.
