The present invention provides a liquid crystal composition comprising one or more compounds of general formula I and one or more compounds of general formula II; the liquid crystal composition of the present invention can work at very high and very low temperatures, has a very short response time and a better reliability to light and heat, and particularly exhibits no image retention or a significantly reduced image retention after a long time operation.

The present disclosure provides a liquid crystal display panel and a liquid crystal display device, and relate to a field of display technology. The liquid crystal display panel comprises an array substrate (ARR) and a color film substrate (CF) which are cell-assembled, and a liquid crystal layer (LC) disposed between the array substrate (ARR) and the color film (CF) substrate. Wherein the liquid crystal layer (LC) comprises a negative liquid crystal composition; the total mass content of monomers containing dibenzothiophene structure and monomers containing dibenzofuran structure in the negative liquid crystal composition is not more than 2%.

The new LC media exhibit a new spontaneous, self-supporting ferroelectric smectic phase. They typically comprise one or more dielectrical neutral, aromatic compounds described further in the description in a highly polar host mixture typical for ferro-electric nematic mixtures. The mixtures are useful for electro-optics, electronics, electro-mechanic and other applications for materials with very high dielectric permittivity. In addition, the present invention relates to liquid crystal devices, electric and electronic elements which contain the liquid crystalline media according to the invention.
