The present application includes a pair of substrates disposed opposite to each other, an electrode group formed on one or both of the opposed surfaces of each of the pair of substrates, a plurality of active elements connected to the electrode group, A liquid crystal alignment film formed on opposing surfaces of each of the pair of substrates, and a liquid crystal layer formed between the pair of substrates; the alignment film has a photoisomerization structure in the main chain A coating obtained from polyamic acid or a derivative thereof or a film obtained through the step of firing the coating is produced through a step of imparting alignment control ability by irradiating linearly polarized light; and the liquid crystal The layer relates to a liquid crystal display element which is a liquid crystal composition having negative dielectric anisotropy. According to the present invention, a liquid crystal display element having excellent afterimage characteristics and good alignment stability can be provided. |
