[Problem] The present invention provides a liquid crystal display element, which is characterized by high vertical alignment of liquid crystal and good optical characteristics, that is, the transparency when no voltage is applied and the scattering characteristics when voltage is applied. The liquid crystal alignment film has high adhesiveness, and can maintain these characteristics even under an environment of high temperature and high humidity or exposed to light for a long time. [Solution] By using a compound of the following formula [1a] and a liquid crystal composition for a liquid crystal display element, the purpose of the present invention is achieved, The definition of the symbol in the formula is as described in the description. |
