PROBLEM TO BE SOLVED: To permit viewing even in a light room, to directly instruct an image on a screen and to unnecessitate a new install place by composing a desk of a display device. SOLUTION: Projecting light 2 outputted from a projector 5, which is attached to a casing 10 by a fixing screw or the like so as to turn a projecting lens downward, is reflected toward a mirror b14 by a mirror a13, further reflected toward a transmission type screen 8 by the mirror b14 and made incident at an angle with which the optical axis center of the projecting light 2 can perpendicularly cross the transmission type screen 8 for image formation. A front panel 17 formed from transparent reinforced glass or reinforced resin, for example, is arranged on the surface of the transmission type screen 8, reflection-proof coating is applied to that surface for preventing the reflection of external light or peripheral light, and the surface has an effect similar to the top plate of the desk and protects the transmission screen 8 as well. In a conference or the like, a participant sits down in front of the device, which is also used as a desk, and can watch information displayed on the device while watching documents or the like on the device together. |
