Abstract

The present invention provides a polymerizable liquid crystal composition, which has a lower melting point and a longer supercooling time. Meanwhile, the value of the refractive index no of the polymerizable liquid crystal composition is between 1.495-1.502, and the value of the birefringence Δn is between 0.145-0.180. The present invention also provides the application of the polymerizable liquid crystal composition in naked-eye 3D display.

Description

technical field [0001] The invention relates to a polymerizable liquid crystal composition and its application in naked-eye 3D display. Background technique [0002] In recent years, with the development of the information society, simple liquid crystal displays can no longer meet people's demand for display, and it is necessary to use optical anisotropic bodies with various functions to help improve the quality of display. For example, using retardation film for optical compensation to improve viewing angle characteristics, using incremental film for light recycling to improve optical efficiency, or using patterned retardation film or lenticular lens film to change optical parameters to achieve 2D / 3D display conversion. [0003] In the prior art, ordinary polymers or polymerizable liquid crystal monomers are generally used for optically anisotropic bodies, but optically anisotropic bodies (such as polycarbonate films) made of ordinary polymers have too large a thickness and...
