Abstract

The problem that the invention object to resolve is to provide a polymerizable compound, which has excellent solubility with other liquid crystal compounds during constituting a polymerizable liquid crystal composition, and displays excellent heat-resistant quality and mechanical intensity during curing the polymerizable liquid crystal composition. The invention provides a polymerizable compound represented by formula (I), and a liquid crystal composition taking the compound as the constitution material, and further provides an optical anisotropy body or liquid crystal device using the liquid crystal composition. As the inventive polymerizable compound has excellent solubility with other liquid crystal compounds, it is useful as the constitution material of the polymerizable compound. In addition, the polymerizable composition containing the inventive polymerizable compound has wide liquid crystal phase temperature range; the optical anisotropy body of the polymerism composition has high heat-resistant quality, and is useful in phase difference plates and the like applications.
