Abstract
An optical filter for a display includes a filter film with at least one optical filter layer. The filter layer blocks a band of optical wavelengths and is transparent for optical wavelengths outside the band. The filter film has a thickness within the range of 25 microns through 1 mm. The filter film may include one or more laminate layers that are optically transparent in the wavelengths of the band blocked by the filter layer. The filter film may include one or more layers of liquid crystal polymers in layered contact with one or more transparent electrode layers and one or more layers of polymers in layered contact with the one or more layers of liquid crystal polymers.
