摘要:
PROBLEM TO BE SOLVED: To provide a reflection screen capable of reducing video reflection to a ceiling as much as possible and displaying an excellent video, and a video display system equipped therewith.SOLUTION: A reflection screen 10 includes: a reflective layer 12 that reflects video light L; and a surface layer 14 arranged closer to a video source side than the reflective layer 12 in a thickness direction of the reflection screen 10, with alignment of a plurality of unit optical shapes 141 on a surface on the video source side. A unit optical shape 141 includes a first surface 142 and a second surface 143, and projects on the video source side. Under a service condition of the reflection screen 10, the first surface 142 is located closer to the video source side than the second surface 143 in an alignment direction of the unit optical shape 141. If angles formed by a surface parallel to the screen surface with the first surface 142 and the second surface 143 are α, &bgr;, respectively, a relation &
