Patent ID: 7859625

Claim:
A manufacturing method of a liquid crystal display device which includes: a pair of substrates; a liquid crystal layer which is sandwiched between the pair of substrates; a first alignment film which is formed on one of opposedly-facing surfaces of the pair of substrates; a second alignment film which is formed on another of opposedly-facing surfaces 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, wherein the first projecting portion is set lower than the second projecting portion, and an area of an upper surface of the first projecting portion is set smaller than an area of an upper surface of the second projecting portion, the manufacturing method of a liquid crystal display device comprising the steps of: forming a photo-decomposition-type polyimide film as the first alignment film by baking a volatile organic solvent containing a photo-decomposition-type polyimide acid having viscosity of not more than 35 mPa·s; and baking the polyimide film by radiating polarized light containing ultraviolet rays to the polyimide film.
