摘要： A projection display apparatus is provided with a projection distance adjustment mechanism for adjusting a distance between a projection plane and an emitting position of projection light, and provided with a focus adjustment mechanism for making a focus adjustment of a projection image with respect to the projection plane. The focus adjustment mechanism is driven such that a projection image is properly focused onto the projection plane in accordance with the distance between the projection plane and the emitting position.

摘要： There are provided a write light valve for generating image-writing light by modulating write light, a driver for writing images into the write light valve based on image data, read light valves for each color for generating respective color image lights by modulating each received color illumination light, an imaging lens group for guiding the image-writing light emitted from the write light valve to the respective read light valves, a dichroic cube for combining together color image lights emitted from the respective read light valves, a projection lens for projecting each color image light combined together. The imaging lens group has a distortion aberration which reduces or cancels out a distortion aberration of the projection lens.

摘要： A projection display device comprises a projection lens section to which light modulated by a light modulating element is entered, a mirror section for reflecting the light emitted from the projection lens section to reflect to the projection lens section side and directing the light to a projection plane, and an operation section for displacing a lens in the projection lens section. The operation section is disposed in a region in which the operation section does not hinder an optical path of the light that has been passed through a projection port provided in a main body cabinet.
