Patent ID: 8066906

Claim:
A polymerizable compound represented by general formula (1): wherein A represents a ring assembly composed of at least two 6-membered rings each optionally having a substituent; X 1 and X 2 each represent a (meth)acryloyloxy group; and Y 1 and Y 2 each independently represent a single bond, an optionally branched alkylene group having 1 to 8 carbon atoms, an ether linkage, —COO—, —OCO—, a 6-membered ring optionally having a substituent, a naphthalene ring optionally having a substituent, or a combination thereof; the substituent being a hydrogen atom, a halogen atom, a nitrile group, an optionally branched alkyl group having 1 to 8 carbon atoms, an optionally branched alkoxy group having 1 to 8 carbon atoms, or an optionally branched alkenyl group having 2 to 8 carbon atoms, wherein the alkyl, alkoxy, or alkenyl group may have its —CH 2 — moiety replaced with a sulfur atom or an oxygen atom and may have its hydrogen atom replaced with a halogen atom or a nitrile group.
