LIQUID CRYSTALLINE COMPOSITION AND LIGHT ABSORPTION ANISOTROPIC FILM, A POLARIZING ELEMENT AND A LIQUID CRYSTAL DISPLAY DEVICE, EACH EMPLOYING THE SAME

摘要

A liquid crystalline composition, having a liquid crystalline dichroic azo dye that is represented by formula (I) and has an expression temperature of the nematic phase of 150° C. to 300° C. in a temperature elevating process, and at least one liquid crystalline dichroic azo dye, wherein an expression temperature of the nematic phase of the liquid crystalline composition is 120° C. or higher in a temperature elevating process: wherein Ar1 and Ar3 each independently represent a substituted or unsubstituted, aromatic hydrocarbon ring group or aromatic heterocyclic group; Ar2 is a divalent substituted or unsubstituted aromatic hydrocarbon group or a divalent substituted or unsubstituted aromatic heterocyclic group; n represents an integer of 1 or more; and when n is an integer of 2 or more, Ar2s may be the same as or different from each other.
