ABSTRACT:
To provide a projection display that can easily switch between rear and front projection modes with a transmission screen, a projector, and a mirror exposed to the outside, a projection display has a projector to project projection light applied to a display image, a mirror to introduce the projection light from the projector, a screen to allow the projection light introduced by the mirror to pass through from the rear to project light in a rear mode, and a frame to hold the projector and the screen. The projection display has the screen, the projector, and the mirror exposed to the outside, and the projector is installed so that it can be attached to and detached from the frame.
