A liquid crystal display panel including a first display substrate, a second display substrate coupled to and spaced apart from the first display substrate, and a liquid crystal layer disposed between the first and second display substrates. The first and second display substrates include inorganic layers containing an inorganic silicon-based material. The liquid crystal layer includes alignment molecules vertically aligned with respect to the inorganic layers, and liquid crystal molecules vertically aligned between the inorganic layers. A manufacturing method of the liquid crystal display panel includes surface-treating the inorganic layers to vertically align the liquid crystal molecules.
