  • Projector including color filters
    Patent number: 11966152
    Abstract: A projector comprises: a light source that projects laser light; a first color filter including a reflective portion reflecting the laser light emitted from the light source, and a transmissive portion transmitting the laser light; a phosphorus plate that converts the laser light reflected from the first color filter into phosphorescent light; a second color filter including color films of different colors through which the phosphorescent light transmits; and a display element that is provided with the laser light transmitted from the first color filter and the phosphorescent light transmitted through the second color filter so as to project an image, wherein the projector can be reduced in volume since the number of lenses used in an optical system can be reduced by shortening an optical path.
