ABSTRACT:
A projection display apparatus comprises luminous bodies, a luminous body driving portion which drives to turn on each of the luminous bodies, light leading members which optically separately lead and project light beams exiting from the luminous bodies, a movable portion which enables relative movement of the light leading members and the luminous bodies, and a light selection control portion which controls the movable portion and/or the luminous body driving portion in such a manner that light beams which enter the light leading members are selected. The apparatus further comprises a light modulation element which performs light modulation, an illumination member which illuminates the light modulation element with light beams from the light leading members, and a display control portion which controls the light selection control portion and the light modulation element in such a manner that the element suitable for light beams from the light leading members is illuminated.
