Zusammenfassung:	An image offset adjustment apparatus for an LCD projector which is constructed to enable the adjustment of an image offset. The LCD projector includes a light source for emitting light, mirrors, and an LCD installed in front of the mirrors so that an image generated in the LCD is enlarged and projected on a screen. The image offset adjustment apparatus includes a projection lens section including a plurality of projection lenses having their respective LCDs at different circumferential positions to have different image offsets; a lens housing for housing the respective projection lenses adjacent to one another in a circumferential direction; rotation means for rotating the lens housing; and a controller for controlling the rotation means so that the lens housing can be controllably rotated to select one of the projection lenses and one of the image offsets as desired by a user.
