摘要： PROBLEM TO BE SOLVED: To provide a projection system capable of restraining a decline in brightness while a user is watching a stereoscopic image.SOLUTION: A projector 1 is so arranged that a polarization element 70 therein is arranged in parallel to a reflection surface 2a of a screen 2. In the projector 1, when light (image light) is transmitted through the polarization element 70, it travels in a direction perpendicular to the polarization element 70, i.e., the direction perpendicular to the reflection surface 2a of the screen 2. Then the image light is projected on to the screen 2 located at a position slanting upward from a projection lens 80. The screen 2 is a reflection type screen that reflects the light by specular reflection. A part of the light reflected on the screen 2 travels in the direction perpendicular to the reflection surface 2a of the screen 2, and enters an appreciator P in front of the screen 2, i.e., a liquid crystal shutter spectacle 3. Accordingly, in the projector 1, when the light is transmitted through the polarization element 70, it is directed so as to be parallel to the light travelling from the screen 2 to the liquid crystal shutter spectacle 3.
