Abstract: A light control film includes a first portion and a second portion laminated to the first portion. The first portion includes a first functional substrate and a plurality of first louvers formed on the first functional substrate. The first functional substrate includes at least one of an optically active layer and a barrier layer. The second portion includes a second functional substrate disposed distal to the first functional substrate and a plurality of second louvers formed on the second functional substrate. The second functional substrate includes at least one of an optically active layer and a barrier layer. The plurality of first louvers extend along a first direction and the plurality of second louvers extend along a second direction. The first direction and the second direction are inclined to each other at an angle that lies within a range from about 70 degrees to about 110 degrees.
