The present invention is a copolymer obtained by condensation, a condensation reaction of a leaving group and a nucleophilic group, of a mixture of the following (A) and (C) with a mixture of (B) and (D), or of a mixture of (A), (B), (C) and (D):
(A) a monomer having two leaving groups and further at least one acid group in a molecule;
(B) a monomer having two nucleophilic groups and further at least one acid group in a molecule;
(C) a monomer having two leaving groups and substantially no acid group in a molecule; and
(D) a monomer having two nucleophilic groups and substantially no acid group in a molecule.
Provided is a compound having a wide temperature range exhibiting liquid crystallinity and excellent precipitation suppression and solubility; and a polymerizable composition, a cured product, an optical film, a polarizing plate, and an image display device, each using the compound. The compound is represented, for example, by Formula (1) or (2).
