摘要： A projecting optical system has a plurality of display panels, a color integrating mirror, a projection optical system, a correcting member, and a lens member. The color integrating mirror, disposed at an angle to any of the display panels, integrates the images displayed on the display panels into a single color-integrated image by reflecting a light component covering a specific wavelength range and transmitting light components covering other wavelength ranges than the specific wavelength range. The projection optical system projects the color-integrated image onto a screen. The correcting member, disposed within the projection optical system, corrects the astigmatic difference caused by the color integrating mirror. The lens member, disposed on the color-integrating-mirror side of the correcting member, corrects the astigmatic difference caused by the color integrating mirror.
