The compound is represented by general formula (i). In the compound, in a group K
i1
, 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
i1
)— and/or —CH(—CN)—, where X
i1
is an oxygen atom, a sulfur atom, NH, or NR
13
; in addition, a group A
i2
, a group A
i3
, or the group K
i1
includes, as a substituent, at least one P
i1
-Sp
i1
- group, where P
i1
is a polymerizable group, and SP
i1
is 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.
