Abstract
The provided is a liquid crystal display panel and a liquid crystal display device. 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%.
