DEPOLARIZNG FILM, PROCESS FOR PRODUCING THE SAME, AND LIQUID-CRYSTAL DISPLAY

摘要

A depolarizing element has conventionally been known which comprises cover glasses and, sandwiched therebetween, an adhesive containing fine particles dispersed therein which are made of a birefringent substance. Although calcite has long been known as the birefringent substance, calcite is difficult to mass-produce. The conventional depolarizing element hence has poor productivity. Ultrashort fibers (11) which have birefringence are used in place of inorganic birefringent crystals which have been used in conventional depolarizing elements, such as calcite. Thus, a depolarizing film (10) is obtained which has excellent productivity and can have a large area.
