A liquid crystal display panel, a fabrication method thereof and a display device are provided. The liquid crystal display panel comprises: an opposed substrate (10) and an array substrate (20) arranged opposite to each other, and a liquid crystal layer (30) filled between the opposed substrate (10) and the array substrate (20). Alignment films (40) having opposite friction directions are provided on opposing surfaces of the opposed substrate (10) and the array substrate (20), respectively. The liquid crystal display panel has a plurality of pixel units which are arranged in array, and each of the pixel units comprises two pixel regions (A, B) along the friction direction of the alignment film. In each of the pixel units, a surface of the opposed substrate (10) facing the liquid crystal layer (30) or a surface of the array substrate (20) facing the liquid crystal layer (30) within at least one of the two pixel regions is inclined, so that a mean value of included angles between long axes of liquid crystal molecules in the liquid crystal layer within one of the two pixel regions and a horizontal plane where the opposed substrate (10) and the array substrate (20) are located and a mean value of included angles between long axes of liquid crystal molecules in the liquid crystal layer within the other of the two pixel regions and the horizontal plane where the opposed substrate (10) and the array substrate (20) are located has a same absolute value and a sum of zero.
