  A method of manufacturing a liquid crystal display element capable of easily improving response characteristics without using a large apparatus is provided. After alignment films 22 and 32 made of a polymer compound including a crosslinkable functional group as a side chain and a bulky skeleton such as an adamantane skeleton are formed in a TFT substrate 20 and a CF substrate 30 , the alignment films 22 and 32 are arranged to face each other, and a liquid crystal layer 40 including liquid crystal molecules 41 is sealed between the alignment films 22 and 32 , and then, in a state where the liquid crystal molecules 41 are aligned to allow long-axis directions thereof to be oblique with respect to a substrate surface, the polymer compound in the alignment films 22 and 32 is reacted to form a polymer compound including a cross-linked structure, and predetermined pretilts are provided to liquid crystal molecules 41 A and 41 B placed in proximity to the alignment films 22 and 32 , respectively.

  There is provided a liquid crystal display device including a liquid crystal display element including a first alignment film and a second alignment film provided on opposing surfaces of a pair of substrates, and a liquid crystal layer arranged between the first alignment film and the second alignment film and including crystal molecules having negative dielectric constant anisotropy. At least the first alignment film includes a compound in which a polymer compound having a first side chain and a second side chain is crosslinked or polymerized. The first side chain has a crosslinkable functional group or a polymerizable functional group. The second side chain has a structure inducing dielectric anisotropy. The liquid crystal molecules are pretilted by the first alignment film.
