ABSTRACT:
Such a polymerizable liquid crystal composition is to be provided that is excellent in stability in a solution state, shows good coating property on a supporting substrate, and has a uniform homeotropic alignment property. The polymerizable liquid crystal composition contains an acrylate compound, an epoxy compound and a bisphenol fluorene compound. The polymerizable liquid crystal composition contains a compound selected from a group of compounds represented by formulae (1-1) and (1-2) as a component (A), a compound selected from a group of compounds represented by formula (2) as a component (B), a compound selected from a group of compounds represented by formulae (3-1) to (3-3) as a component (C) and a compound selected from a group of compounds represented by formulae (4-1A), (4-1B), (4-2), (4-3), (4-4) and (4-5) as a component (D), and may optionally contain a compound selected from a group of compounds represented by formulae (5-1) and (5-2) as a component (E). The bisphenol fluorene compound is effective for controlling a uniform homeotropic alignment of the polymerizable liquid crystal composition.
