PROBLEM TO BE SOLVED: To provide a polymerizable liquid crystalline compound having a wide temperature range of a liquid crystal phase, excellent compatibility with other compounds, and further having necessary characteristics such as optical anisotropy, transparency and mechanical properties. Polymer with excellent properties such as mechanical strength, applicability, solubility, crystallinity, shrinkage, water permeability, water absorption, melting point, glass transition point, clearing point, chemical resistance, etc. Provided are a molded article having a directivity, and a liquid crystal display element containing the polymer. A compound represented by the following formula (1) or (2): Ra-Z- (AZ) m-Rb (1) Ra-Z- (AZ) m-Ra (2) Wherein R a is a polymerizable group; R b is a terminal group such as alkyl or alkoxy; A is a ring such as 1,4-cyclohexylene or 1,4-phenylene, and at least one A is 2,3-bis (trifluoromethyl) -1,4-phenylene; Z is a single bond, a bonding group such as alkylene, oxyalkylene, or —COO—; m is an integer of 1-6.
