摘要:
A projection apparatus including an illumination system, a reflective light valve, a projection lens, and a color filter is provided. The illumination system has a light source for providing an illumination beam, and the reflective light valve is disposed on the transmission path of the illumination beam. The reflective light valve has a plurality of pixels arranged in an array for converting the illumination beam into an image, and the projection lens is disposed on the transmission path of the image. The color filter is disposed between the light source and the reflective light valve and on the transmission path of the illumination beam. Moreover, the color filter includes a transparent substrate and a color filter array disposed on a first surface of the transparent substrate. The color filter array includes a plurality of filter patterns, and each of the filter patterns corresponds to one of the pixels, respectively.
