PROBLEM TO BE SOLVED: To obtain a projection device which is suitable for an advertisement stage since the projection device for the advertisement stage is required to satisfy requirements, such as not to disturb customers' fields of vision of the customers and to be made simple in installation, disassembly and movement, not to require space for installation (for example, to be short in the distance between a screen and projectors) but diversion of the conventional projectors as the projectors for the advertisement stage is heretofore infeasible. SOLUTION: This projection device has the screen 3 which is at least any among a screen as a background of the stage, a screen as the background of a show window, a screen for propaganda and advertisement of a conventional hall or a screen for propaganda and advertisement on a building roof and the plural projectors disposed on both sides of the front surface side of the screen 3. The plural projectors project the same images from diagonal directions to the screen 3. The projectors themselves do not disturb the fields of views to the customers and occupy only small floor spaces. The projection device is thus optimum as the projection device for the advertisement stage.
