Polymerizable compound, polymerizable resin composition, cured polymer and liquid crystal display device

A polymerizable compound represented by general formula (I):

• where R is H, R′, R′O, R′COO, or R′OCO, R′ is a linear or branched alkyl group or alkenyl group having 1 to about 15 carbon atoms;
• A1 and A2 are independently a cyclohexane ring or a benzene ring which may include a substituent represented by formula (II) below;
• X is H or CH3;
• and Y1, Y2, Y3 and Y4 are independently H, F, Cl, CH3, CH3O, CF3, or CF3O wherein at least two of Y1, Y2, Y3, and Y4 is H and, if both A1 and A2 are cyclohexane rings, at least one of Y1, Y2, Y3, and Y4 is not H, and if A1 is a cyclohexane ring and A2 is a benzene ring, at least one of Y1, Y2, Y3 and Y4 is not H:
• where Y5, Y6, Y7, and Y8 are independently H, F, Cl, CH3, CH3O, CF3, or CF3O, at least two of Y5, Y6, Y7, and Y8 are H.
