Abstract
A display includes a display modulation layer, a backlight unit configured to generate light for illumination of the display modulation layer, and a filter film disposed between the backlight unit and the display modulation layer. The filter film includes a plurality of Bragg grating sets. Each Bragg grating set is configured to reflect the light in a wavelength-selective and angular-selective manner rearward toward the backlight unit.
