| abstract |
The present invention pertains to a compound represented by general formula (i), wherein at least two secondary carbon atoms in an alkyl group (linear alkyl group, halogenated alkyl group or cyanated alkyl group having 3-40 carbon atoms) of group K i1 are substituted with -C(=X i1 )- and/or -CH(CN)-(X i1 is an oxygen atom, a sulfur atom, NH or NR 13 ), and group A i2 , A i3 or K i1 has, as a substituent, at least one P i1 -Sp i1 -group (P i1 is a polymerizable group, and Sp i1 is a spacer group or a single bond). The compound represented by general formula (i) is contained in a liquid crystal composition, whereby the liquid crystal composition is adsorbed on a substrate clamping a liquid crystal layer, and liquid crystal molecules can be held in a state of being aligned in the vertical direction without an alignment film. |
