Abstract
A color filtering device including a color filter, a plurality of polarization beam splitting units, a plurality of reflecting units, and a plurality of wave plates is provided. The color filter has a plurality of filtering parts and a plurality of light shielding parts alternately arranged thereon. Each of the polarization beam splitting units is disposed in front of one of the filtering parts and makes an angle with a corresponding filtering part. Each of the reflecting units is disposed in front of one of the light shielding parts and makes an angle with a corresponding light shielding part. Each of the wave plates is substantially parallel to one of the filtering parts. Each of the polarization beam splitting units is disposed between a pair of a wave plate and a filtering part. The color filtering device has both color filtering function and polarization conversion function.
