PURPOSE:To raise a contrast and to widen an observable range in the horizontal and vertical directions by mixing 0.5-10wt% a light scattering material whose particle diameter is 0.5-50mum into a transparent base having a lenticular lens all over its surface. CONSTITUTION:A lenticular lens 11 and a light shielding layer 12 are provided on one surface of a transparent base consisting of a transparent synthetic resin, and a light shielding part on the other surface, respectively. Subsequently, a colored light scttering material 14 which is an organic or inorganic material and has a particle diameter of 0.5-50mum is kneaded by 0.5-10wt.pts. to 100wt.pts. synthetic resin. In this way, it is possible to obtain a screen which has the spread of an emitted light in not only the horizontal direction but also the vertical direction, has a high picture contrast, and also has a wide observable range in the vertical direction. |
