Patent ID: 7901092

Claim:
A projection display device, comprising: 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 a projection plane; a main body cabinet for accommodating the projection lens section and the mirror section, wherein the main body cabinet includes a first side surface having a light projection port and a second side surface facing the first side surface, and the mirror section is arranged shifted from an optical axis of the projection lens section, and the second side surface is formed to conform to the shifted arrangement of the mirror section with respect to the projection lens section such that the second side surface is at different height levels with respect to a plane on which the second side surface is placed; and a level difference correction section for changing a height level of the second side surface with respect to the plane on which the second side surface is placed to orient the light from the mirror section in a desired direction, when the main body cabinet is placed on the plane on which the second side surface is placed in a state that the second side surface faces the plane.
