  • Compound, cured product, polymer, photo-alignment film, optically anisotropic body and liquid crystal display element
    Patent number: 10738242
    Abstract: A compound and a polymer which can each form a photo-alignment film having excellent ability of controlling alignment, a photo-alignment film obtained using the polymer and an optically anisotropic body and a liquid crystal display element each having the photo-alignment film are provided. A compound represented by the general formula (1). In the formula, P represents a polymerizable group, Z and Z1 represent divalent linking groups, A and A1 represent divalent cyclic groups, and X1 to X5 each independently represent a hydrogen atom, a fluorine atom, a chlorine atom, a hydroxy group, a nitro group, a cyano group or an alkyl group having 1 to 40 carbon atoms which may have a substituent, provided that X1, X2, X4 and X5 are not simultaneously hydrogen atoms.
