A color filter, a display device using the color filter, and a method for preparing the color filter are provided. The color filter is provided with a plurality of pixel regions in one-to-one correspondence to light within a plurality of different wavebands, respectively. The color filer comprises a plurality of stacked dielectric films. Each of the dielectric films reflects light within one waveband and transmits light within other wavebands.

摘要:
The reflectivity and transmissivity of building and vehicle surfaces is maintained while employing partial, variable, selective, or asymmetric diffusers between a surface and an external light source such that the reflected light is diffused to produce a reduction in glare, while minimally effecting the specular or collimated transmission (if any) of light through the surface. Glare is also reduced by utilizing diffuser devices that reflect light in a temperature dependent manner.
