Abstract:
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.
