Abstract
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. In each of the pixel regions, the dielectric film for reflecting light within a waveband corresponding to this pixel region is replaced with a polarization-separation film for reflecting light in a first polarization direction and transmitting light in a second polarization direction. The color filter provided by embodiments of the present invention improves the transmittance of incident light and the utilization ratio of the incident light and can further provide powerful technical support for the enhancement of image display quality.
