Provided is a liquid crystal display element having a high vertical orientation of liquid crystal, good transparency in the absence of a voltage, good scattering characteristics at the time of voltage application, and high adhesion with a liquid crystal layer. A liquid crystal composition comprising a liquid crystal arranged between a pair of substrates provided with electrodes and a liquid crystal composition containing a polymerizable compound and having a liquid crystal layer cured by irradiation of ultraviolet rays and at least one of the substrates has a liquid crystal alignment layer And a side chain structure represented by the following formula [2-1] or [2-2] and a side chain structure represented by the following formula [3], which contains a compound represented by the formula [1] Of the liquid crystal alignment treatment agent. (X 1 : X 2 , X 3 , X 4 and X 6 : single bond, X 5 and X 7 : benzene ring and the like, X 8 : C 1 alkyl group, such as to 18) (X a: such as H, X B: benzene ring, X C: alkyl group) (Y 1, Y 2 and Y 3 of C 1~18: a single bond, etc., Y 4 and Y 5 Y 6 is a C 1 to C 18 alkyl group, etc. (Y 7 is a single bond, Y 8 is a C 8 to C 22 alkyl group, etc.) |
