PROBLEM TO BE SOLVED: To further improve energy saving effects by reducing a loss of image light projected from a projector in an optical path to reaching eyes of a person, in a screen system configured to irradiate a limited narrow area with the image light from the projector.SOLUTION: The screen system includes: a reflector 22 forming a part of a substantial spheroid 20; and a projector 38 in which an optical system iris is located at a first focus vicinity 26 of the substantial spheroid 20 and which is disposed facing the reflector 22. Consequently, image light from the projector 38 can be viewed at a second focus vicinity 28 of the substantial spheroid 20 in a direction toward the reflector 22. |
