ABSTRACT:
An optically anisotropic element comprises a discotic compound. The discotic compound has an oriented discotic plane. The discotic compound has a molecular structure represented by the formula (I) of D(—O—CO—CR1═CR2—X—R3)n. In the formula (I), D is a discotic core, n is an integer of 3 to 20, each of R1and R2is hydrogen, a halogen atom or an alkyl group, X is —O—, —S— or —NR—, and R3is an alkyl group or an aryl group. A polymerizable discotic compound having an oriented discotic plane can be polymerized to form an optically anisotropic element. Alignment of the oriented discotic plane is fixed by polymerization. A new discotic compound is also disclosed.
