The invention provides a production method for a liquid crystal display panel. According to the method, traditional ITO transparent conductive films on a TFT (thin film transistor) substrate and a CF (color filter) substrate are replaced with graphene/PEDOT:PSS composite transparent conductive films, polar materials are added to a liquid crystal mixture of the liquid crystal display panel, and a general structural formula of the polar materials is A-B; the head group A is mainly used for enabling larger intermolecular force to be generated between the polar materials and the graphene/PEDOT:PSS composite transparent conductive films; similar to a function of a PI branch chain, the tail group B is mainly used for enabling liquid crystal molecules to be arranged vertically in a steric hindrance manner and has a vertical alignment effect; that is, the polar materials can generate larger intermolecular force with the graphene/PEDOT:PSS composite transparent conductive films so as to be vertically arranged on the surface of the TFT substrate and the CF substrate, the liquid crystal molecules are guided to be arranged vertically, the polar materials are substituted for a PI alignment film to have a liquid crystal alignment effect, a PI alignment film preparation process is omitted, the production cost of the alignment film is reduced, and the capacity is improved.
