Optical component and light control film including same

An optical component comprising:

• a substrate extending along orthogonal length and width directions of the 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 thickness direction orthogonal to the length and width directions, the first major surface of the substrate comprising a plurality of alignment features, each alignment feature of the plurality of alignment features configured to engage with a corresponding structure of a mating component comprising a plurality of structures extending from a substrate along the thickness direction when the optical and mating components are mated to each another with the structures of the optical and mating components interleaved and disposed between the substrates of the optical and mating components, the structures of the optical and mating components having a substantially same average height H1 along the thickness direction and extending along the length direction and arranged substantially periodically along the width direction at a substantially same average pitch P1, the structures of the optical and mating components having respective average widths W1a and W1b along the width direction, H1/(P1−W1a−W1b)≥1, the plurality of alignment features configured to align the optical and mating components along at least the width direction.
