In formula (I), Prepresents a polymerizable group; each of Land Lrepresents a divalent spacer group; each of Zto Zrepresents a divalent linking group; each of Aand Arepresents a divalent cyclic group; each of m and n represents an integer from 0 to 3; MA represents any one group of A-I to A-V below: 

Liquid crystal composition and retardation film

An optical film comprising at least one compound represented by formula (1) is disclosed. In the formula, Y, Yand Yeach independently represent methine or a nitrogen atom; R, Rand Reach independently represent formula (A), (B) or (C) or a hydrogen atom, provided that at least two of R, Rand Reach independently represent formula (A), (B) or (C). In the formulae, L, L, and Leach represent a 5-membered heterocyclic group. 

A new liquid crystal compound comprises two condensed and substituted rings. The ring preferably is a five-membered heterocyclic ring. The heterocyclic ring is preferably condensed with benzene ring or an aromatic six-membered heterocyclic ring. The benzene ring or the aromatic six-membered heterocyclic ring is preferably substituted with a group comprising a cyclic structure and a chain structure. The liquid crystal compound is advantageously used in preparation of a thin phase retarder, such as a wide-ranged &#x3bb;/4 plate, which gives inverse wavelength distribution. The phase retarder can be easily produced according to a simple process by using the new liquid crystal compound.
