Abstract
The compound is represented by general formula (i). In the compound, in a group K, at least two secondary carbon atoms in an alkyl group (a linear alkyl, halogenated alkyl, or cyanogenated alkyl group having 3 to 40 carbon atoms) are replaced with —C(═X)— and/or —CH(—CN)—, where Xis an oxygen atom, a sulfur atom, NH, or NR; in addition, a group A, a group A, or the group Kincludes, as a substituent, at least one P-Sp- group, where Pis a polymerizable group, and SPis a spacer group or a single bond. The liquid crystal composition including the compound represented by general formula (i) can be adsorbed onto substrates between which a liquid crystal layer is held, and, consequently, without the use of an alignment film, liquid crystal molecules can be maintained in a state in which the liquid crystal molecules are aligned in a vertical direction.
