Claim:
1. A compound represented by general formula (I): wherein L is a polymerizable group; Sp is a spacer unit comprising methylene; Q is a direct bond, —O—,—CO—O—, or —O—CO—; A comprises a group selected from the group consisting of trans-1,4-cyclohexylene (wherein one or more non-adjacent methylene groups present in this group are optionally replaced with —O—, —NH—, or —S—), 1,4-phenylene (wherein one or more —CH═groups present in this group are optionally replaced with—N═), 1,4-cyclohexenylene, 2,5-thiophenylene, 2,5-furanylene, 1,4-bicyclo[2,2,2]octylene, naphdialene-1,4-diyl, naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl, and 1,2,3,4-tetrahydronaphthalene-2,6-diyi, wherein the groups are unsubstituted, or one or more hydrogen atoms present therein are optionally replaced with fluorine, chlorine, cyano, methyl, or methoxy; s is an integer of 1 to 4, wherein ifs is 2 to 4, each A may be the same or different; X and Y are each independently hydrogen, fluorine, chlorine, cyano, or an alkyl group of 1 to 20 carbon atoms, wherein any hydrogen atom present in the alkyl group is optionally replaced with fluorine, and if one or more non-adjacent methylene groups are present in the alkyl group, the one or more non-adjacent methylene groups are optionally replaced with —O—, —CO—O—, —O—CO—, and/or —CH═CH—, and M is any of general. formulas (IIa), (IIb), and (IIc): wherein the dashed line is a linkage to the carbon atom; R R if one or more non-adjacent methylene groups are present in R
