摘要：
A light diffusing film having superior productivity can be obtained by using very short fibers as a substitute for conventional spherical fine particles as light diffusing material. It is possible to mass-produce very short fibers at low cost, for example, by cutting fibers. Further, it is relatively easy to obtain very short fibers with a narrow fiber length distribution. The use of this makes it possible to carry out more highly sophisticated optical design of light diffusing films.
