PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid crystal display device which is improved in panel numerical aperture while keeping a response characteristic to a voltage excellent in a display mode using liquid crystal having negative permittivity anisotropy. SOLUTION: A method of manufacturing a liquid crystal panel having negative permittivity anisotropy includes a step of hermetically sealing a liquid crystal layer 30 between a TFT substrate 10 and a CF substrate 20 through vertical alignment films 11 and 21, and a step of exposing the entire surface of the liquid crystal layer 30 to light while a voltage V is applied between the substrates 10 and 20. Surfaces of the vertical alignment films 11 and 21 opposed to the liquid crystal layer 30 are rubbed as specified. Liquid crystal molecules 30A can be held in a pretilt state without providing a projection nor a slit to a substrate and an electrode, so the panel numerical aperture can be improved while the voltage response characteristic is maintained.
