Description

technical field The present invention relates to a composition containing a compound capable of imparting inverse wavelength dispersibility to a film when added to the film, and a rod-shaped compound and a cellulose compound. The invention also relates to cellulose films containing these compounds. The present invention also relates to an optical film, a polarizing plate and a liquid crystal display device using the optical film. In particular, the present invention relates to an optical film, a polarizing plate, and a liquid crystal display device realizing high clear visibility with low viewing angle dependence. Background technique Liquid crystal display devices are increasingly used year by year as space-saving, low-power image display devices. Traditionally, the main disadvantage of liquid crystal display devices is that the viewing angle dependence of the image is very large, but in recent years, various high viewing angle modes in which liquid crystal molecules are ...
