Abstract
A projection display device includes an imager which modulates light from a light source based on an image signal; a projection optical system which enlarges and projects the light modulated by the imager onto a projection plane; and a shift mechanism which displaces the imager in a direction intersecting with an optical axis of the projection optical system. The projection optical system and the shift mechanism are co-mounted on a base member.
