Abstract

A light control device is disclosed that includes a two film construction, each film having a plurality of light reflecting regions. For example, the light absorbing elements can be a series of grooves or column-like indentations in the films that are filled or coated with a light reflecting material having a lower index of refraction than that of the films. The two films can be adjacently disposed so that their respective light reflecting regions form a plurality of light reflecting elements that extend along the thickness direction of the device.
