The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises an opposite substrate, an array substrate and a liquid crystal layer, wherein the opposite substrate and the array substrate are oppositely arranged, the liquid crystal layer fills a space between the opposite substrate and the array substrate, the liquid display panel is provided with a plurality of pixel units which are arranged in an array way, at least one hole-shaped groove is formed in the surface, corresponding to the opposite substrate and/or the array substrate, of each pixel unit, and is in a circular truncated cone shape with an increasingly enlarged opening, and the opposite surfaces of the opposite substrate and the array substrate are respectively provided with an orientation layer. The liquid crystal display panel has the advantages that when electric voltage is not applied, a long axis of a liquid crystal molecule in the liquid crystal layer corresponding to each pixel unit is vertical to the orientation layer with the action force on the corresponding liquid crystal molecule, so the liquid crystal molecule has certain inclining angle when the electric voltage is not applied; when the voltage is applied to the display panel, the liquid crystal molecule can be quickly turned to the proper position, so the response speed of the liquid crystal molecule is improved, the response speed of an inputted voltage signal is followed, the ghost effect of a picture is improved, and the quality of the picture is further improved.
