Abstract

The invention relates to a liquid crystal composition, a liquid crystal display element containing the liquid crystal composition and a liquid crystal display, and belongs to the field of liquid crystal display. The liquid crystal composition disclosed by the invention comprises a compound shown as a formula I, one or more compounds shown as a formula II and one or more polymerizable compounds, and the liquid crystal composition has a large K value, a relatively high clearing point (CP) and a large dielectric property (delta epsilon).

Description

technical field [0001] The present disclosure belongs to the field of liquid crystal display, and more specifically relates to a liquid crystal composition, a liquid crystal display element and a liquid crystal display containing the liquid crystal composition. Background technique [0002] Liquid crystal display elements are divided into the following modes according to the display mode: twisted nematic (TN) mode, super twisted nematic (STN) mode, in-plane mode (IPS), and vertical alignment (VA) mode. Regardless of the display mode, the liquid crystal composition needs to have the following characteristics: [0003] (1) stable chemical and physical properties; (2) low viscosity; (3) suitable dielectric Δε; (4) suitable refractive index Δn; (5) good miscibility with other liquid crystal compounds. [0004] The early commercial TFT-LCD products basically adopted the TN display mode, and the biggest problem was the narrow viewing angle. With the increase of product size, esp...
