Abstract

The invention relates to a negative dielectric anisotropic liquid crystal composition and a liquid crystal display device. The negative dielectric anisotropic liquid crystal composition comprises at least one compound as shown in a formula I and at least one polymerizable compound as shown in a formula II, and the polymerizable compound as shown in the formula II and a specific compound as shown in the formula I are combined for use, so that the PSVA liquid crystal composition is particularly suitable for display or TV application.

Description

technical field [0001] The invention relates to the field of liquid crystal display materials, in particular to a liquid crystal composition formed by matching a specific polymerizable compound with a specific liquid crystal component, and a display element or a liquid crystal display containing the liquid crystal composition. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has gone through a long period of basic research. After realizing mass production and commercialization, it has become a mainstream product in LCD applications due to its advantages of lightness, lightness, environmental protection, and high performance: whether it is a small size TFT-LCD applications can be seen everywhere in mobile phone screens, large-sized notebook computers or monitors (Monitor), and large-scale LCD TVs (LCD-TV). [0003] The early commercial TFT-LCD products basically adopted the TN display mode, and the biggest problem was the narrow viewing angl...
