| description | The invention discloses a polymerizable liquid crystal compound, a liquid crystal optical film based on the polymerizable liquid crystal compound and a preparation method, and belongs to the technical field of liquid crystal compounds for optical devices. The polymerizable liquid crystal compound disclosed by the present invention has a low melting point and appropriate solubility while having a high birefringence due to the use of a molecular skeleton having a large [pi]-[pi] conjugation and lateral substituent groups of different volumes, and thus provides an optically anisotropic body having an excellent retardation value at a thinner film thickness. According to the liquid crystal optical film containing the polymerizable liquid crystal compound, the polymerizable liquid crystal compound with high birefringence is used, so that the liquid crystal optical film has larger retardation and thinner film layer thickness.
