Abstract
A liquid crystal display device which can reduce or eliminate a display defect is provided. The liquid crystal display device includes a first alignment film formed on one of the pair of substrates; a second alignment film formed on another of the pair of substrates; first projecting portions which are provided to the first alignment film and project into the liquid crystal layer by first constitutional members which constitute a layer below the first alignment film; and second projecting portions which are provided to the second alignment film, face the first projecting portions, and project into the liquid crystal layer by second constitutional members which constitute a layer below the second alignment film, the first projecting portion being set lower than the second projecting portion, and an area of an upper surface of the first projecting portion being set smaller than an area of an upper surface of the second projecting portion. The first alignment film is made of a photo-decomposition-type alignment film material.
