Liquid crystal medium

By doping the liquid crystal medium with dichroic dyes and Formula I compounds, the contrast and transmittance of the liquid crystal display are optimized, solving the problems of viewing angle dependence and dark-state image quality, and realizing a liquid crystal display with high transmittance, low power consumption and wide viewing angle.
