摘要： A projection display device includes: a projection portion which enlarges and projects the light modulated by a imager portion; a control circuit; and a main body cabinet. The projection portion is formed by a projection lens portion into which the light from the imager portion is entered and a mirror portion which reflects the light having passed through the projection lens portion and lets the light travel toward a projection plane. The mirror portion is disposed so as to be shifted from an optical axis of the projection lens portion in a direction opposite to a direction in which the incident light from the projection lens portion is turned back. The control circuit portion is disposed in a space which is produced between the projection lens portion and the main body cabinet by a position gap between the projection lens portion and the mirror portion.
