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.
