<P>PROBLEM TO BE SOLVED: To provide a light scattering film whose layer configuration is simple and which has a stable optical characteristic and is easily attached to a display device in applying the light scattering film used for control of a view angle to the display device. <P>SOLUTION: In the light scattering film, portions with different refractive indexes are distributed in irregular shape and thickness within a film to form band-shaped lightness and darkness due to the highness and lowness of the refractive indexes. The light scattering film has, at a particular film cross section, a layered cross section in which the extending direction of the band- shaped lightness and darkness is inclined with respect to the principal plane of the film. The light scattering film itself is given adhesion properties. <P>COPYRIGHT: (C)2003,JPO |
