Abstract
The purpose the invention is to provide a polymerizable liquid crystal compound which has an excellent solubility with other compounds, a high homeotropic property, and a spirobiindan-backbone, and a liquid crystal composition comprising this compound. The purpose is attained with a polymerizable liquid crystal compound represented by Formula (1). A polymer which is excellent in many characteristics can be obtained from this compound and a formed body having optical anisotropy, produced from this polymer can be obtained. In Formula (1), G is a single bond or oxygen; R is hydrogen, methyl (Me) or a group represented by Formula (a), wherein at least two of R are groups represented by Formula (a); P is a polymerizable group represented by any of Formula (P1) to Formula (P8). In Formula (a), a desirable A is 1,4-cyclohexylene or 1,4-phenylene; Z is a bonding group; m is an integer of 0 to 3; Xis a single bond or alkylene; Zis a single bond, —O—, —OCO—, or —OCOO—; X is a single bond or alkylene.
