PURPOSE:To improve a view field angle and contrast, by forming a masking layer on only a transmission part of a lenticular lens, subsequently, forming a light forming layer, etc., and after that, exfoliating the masking layer of the transmission part together with a light absorbing layer. CONSTITUTION:On only a transmission part 12 of a lenticular lens 1, a masking layer 2 is formed. Subsequently, on the lenticular face, a reflecting layer 3 and also a light absorbing layer 4 are formed. Subsequently, the masking layer 2 is exfoliated together with the reflecting layer 3 and the light absorbing layer 4 on its part, to obtaine a screen. As for a back projection screen obtained in this way, its view field angle is made remarkably large by the lenticular face having a total reflection part, and also it can be improved to an excellent one having a high contrast owing to existence of the light absorbing layer. |
