Abstract
On the outside of a body of a projector, an LCD is provided for displaying an image. A lamp is incorporated in the projector body for illuminating from the rear an image displayed on the LCD. A movable member is provided on the outside of the projector body for vertical swinging movement between open and closed states, and, in the closed state, allows the LCD to be directly observed. A projecting head is provided on the movable member for projecting, in the open state, the image illuminated by the lamp onto a screen outside the projector body.
