Abstract

The present invention provides a liquid crystal display device that can prevent a decrease in the VHR and image sticking on the display screen because of residual DC voltage, and also can produce favorable alignment conditions; and a production method thereof. The liquid crystal display device of the present invention includes: a pair of substrates; a liquid crystal layer that contains liquid crystal molecules and is disposed between the pair of substrates; and an alignment film that is disposed on a liquid crystal layer side of at least one of the pair of substrates, the alignment film containing a polyamic acid or a polyimide with an imidization ratio of less than 100%, the liquid crystal display device including a monomolecular film on the alignment film.
