The present invention provides a compound represented by the general formula (i), which has a partial structure K.sup.i1 represented 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.sup.i2 (R.sup.i2 denotes 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, —CH.sub.2— in the alkyl or halogenated alkyl group is optionally substituted with —CH═CH—, —O—, —COO—, or —OCO—, but —O— is not adjacent to another —O—). 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.

A fluorocarboxylic acid-containing polymer comprising recurring units having formula (A1), but not acid labile group-containing recurring units is provided. A resist composition comprising the same offers a high sensitivity and is unsusceptible to nano-bridging or pattern collapse independent of whether it is of positive or negative tone.
