摘要：
A reflecting screen 10 comprises a base portion 11, light transmitting portions 12 provided on the base portion 11, and light absorbing portions 14. Each of the light transmitting portions 12 comprises a unit prism shape 12 which has a generally wedge-like shape with a larger width on the image source side than its width on the rear face side and is arranged along a screen face 10a. A reflecting layer 13 adapted to reflect the image light, which has been transmitted through the unit prism shapes 12, is provided on the rear face side of each unit prism shape 12. Each unit prism shape 2 extends linearly, and each light absorbing portion 14 is arranged between each adjacent pair of the unit prism shapes 12.
