    摘要: 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 113a and the plane of total reflection 113b, 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.

    摘要: A lenticular lens sheet comprising a base member in the form of a film or sheet, and a lens area including lenticular lenses convexly formed on the light-entering surface of the base member. The lens area is formed by using an ionizing-radiation-curable resin such as an ultraviolet-light- or electron-beam-curable resin. A non-colored layer which is substantially transparent and non-colored is formed in each lenticular lens on the base side thereof; and a colored layer is formed in each lenticular lens along the light-entering surface thereof. The colored layer has the function of enhancing the contrast of the incident-side single lenticular lens sheet. According to this lenticular lens sheet, it is possible to obtain enhanced contrast by preventing the reflection of extraneous light without lowering the intensity of imaging light so much, and to make the lenticular lens pitch extremely small.
