An object of the present invention is to provide a screen frame (214), which is capable of producing clear three-dimensional video images with a simple structure. The screen frame (214) is provided with a frame structure which is like a frame having a window space (216) enclosing a screen (212) at a prescribed distance from the screen (212); the window space (216) is smaller than the screen (212) so that no other part than the screen (212) can be seen through the window space in a prescribed range of viewing angle. When the screen frame (214) is used, the viewer views the screen (212) as if he or she were watching an outdoor scene through the real window and felt a visual depth in the scene. Further, the video images on the screen can be clear by removing influence of peripheral light.
