The present invention provides a compound represented by the general formula (i), which has a partial structure Krepresented by one of the general formulae (K-1) to (K-6) and has a ring B with at least one P-Sp- group and with at least one R(Rdenotes a linear or branched alkyl group having 2 to 10 carbon atoms or a linear or branched halogenated alkyl group having 2 to 10 carbon atoms, &#x2014;CH&#x2014; in the alkyl or halogenated alkyl group is optionally substituted with &#x2014;CH&#x2550;CH&#x2014;, &#x2014;O&#x2014;, &#x2014;COO&#x2014;, or &#x2014;OCO&#x2014;, but &#x2014;O&#x2014; is not adjacent to another &#x2014;O&#x2014;). Thus, the compound in a liquid crystal composition adsorbs to substrates between which the liquid crystal composition (a liquid crystal layer) exists. The compound can hold vertically aligned liquid crystal molecules, can improve alignment stability, and can ensure low-temperature storage stability.

Polymerizable compound as well as liquid crystal composition and liquid crystal display device each including polymerizable compound

[Object] An object of the present invention is to provide a liquid crystal composition containing a polymerizable compound for use in the manufacture of a PSA or PSVA liquid crystal display device. The polymerizable compound has a sufficiently high polymerization rate. The PSA or PSVA liquid crystal display device has few or no display defects due to a change in pretilt angle, has an adequate pretilt angle, and has high responsiveness. The present invention also provides a liquid crystal display device having the liquid crystal composition. [Solution] The object is achieved by using a liquid crystal composition containing one or two or more polymerizable compounds represented by the general formula (I).
