Abstract: A projection display device includes a terminal which is disposed on a surface of a main body cabinet, and a terminal cover which is attached to the surface of the main body cabinet to cover the terminal connected to a cable. In this arrangement, the terminal cover is formed with an opening portion on a surface thereof for passing the cable therethrough, the surface of the terminal cover facing upward when the projection display device is installed in a suspended state.

Abstract: A display device includes a display window, an light emitting portion which is disposed away from the display window by a predetermined distance, and a light guiding portion which is disposed between the display window and the light emitting portion, and which guides light from the light emitting portion to the display window. In this arrangement, the light guiding portion includes a distal end surface located on the side of the display window, and a base end surface located on the side of the light emitting portion. The base end surface has an area larger than an area of the distal end surface. Further, at least a part of the light guiding portion is formed into a tapered portion whose cross sectional area is gradually reduced, as the light guiding portion extends from the base end surface toward the distal end surface.
