A method for producing a liquid crystal display device comprising a pair of spaced and opposed substrates, an electrode and an alignment layer formed on one substrate, an electrode and an alignment layer formed on the other substrate, and a liquid crystal filled between the pair of substrates. The method includes the step of realizing an alignment with a pretilt angle, by irradiating the alignment layer exhibiting a vertically orienting property with ultraviolet rays in an inclined direction through a mask having an opening, wherein the ultraviolet rays are simultaneously irradiated onto a first region of a display portion through the one opening of said mask and onto a second region of the display portion through the one opening of the mask.
