Projection screen and projection display device |
| abstract |
A projection screen 111 comprises a total reflection prism lens 114 and a lenticular lens 115 provided on the viewer's side of the total reflection prism lens 114 . The total reflection prism lens 114 has a plurality of unit prisms 113 on its back surface (the outermost plane of incidence) on which imaging light L is incident. Each unit prism 113 has an apical angle λ that corresponds to the angle between the plane of incidence 113 a and the plane of total reflection 113 b , and the apical angles λ of the unit prisms 113 vary with the position of each unit prism 113 on the screen plane. In particular, the unit prisms 113 have apical angles λ varying continuously from 30° to 45° so that the apical angles λ on the side distant from the center O of the concentric circles are greater than the apical angles λ on the side close to this center O. |
