Problems solved by technology

However, with respect to known liquid crystalline rod-like compounds other than the compounds used, no retardation performance was found when the compounds were added to the cellulose film together with an inverse dispersant
JP-A-2007-249224 discloses that a compound in which a cyclohexyl ring and a benzene ring are linked by an ester bond can be used as an additive for improving the moisture permeability of a certain type of cellulose ester film, but does not disclose about retardation performance of the film

Abstract

A cellulose composition, contains: a cellulose compound; a compound represented by formula (I); and a low molecular weight compound (A); wherein molecular absorption wavelength of the compound (A) derived from an electric dipole transition moment My in a direction approximately orthogonal to a molecular long axis direction, is longer than that derived from an electric dipole transition moment Mx in a direction approximately parallel to the molecular long axis direction; and wherein |My| is larger than |Mx|: wherein L1 to L4 represent a single bond or a specific divalent linking group; Y1 and Y2 represent an alkyl group; Ra, Rb and Rc represent a substituent; m represents an integer of 0 to 4; t represents an integer of 1 or 2; and m11 and m12 represent an integer of 0 to 10.

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 ...
