    • A liquid crystal display device comprises a pair of substrates (1, 2) each having an electrode (13, 5), a liquid crystal layer held between the pair of substrates (1, 2) in which at least two kinds of projections (20, 21) having different projection heights are formed on one of the pair of substrates (1, 2) using the same material. According to one embodiment of the present invention, the liquid crystal display device further comprises a first projection which maintains a constant space between the pair of substrates and a second projection which forms asperities on the electrode to diffuse the reflected light. These projections (20, 21) are obtained by the process comprising the steps, i.e., a resin film formation step of forming a projection resin film on the surface of one of the pair of substrates (1, 2) using photosensitive resin, and a projection formation step of simultaneously forming at least two types of projections (20, 21) having different projection heights on the substrate (2) using a photomask having variable transmittances and conducting exposure and development in such a manner that resulting thickness of the projection resin film can be varied. Thus, liquid crystal display devices comprising several kinds of projections having different heights accurately formed on the predetermined positions can be obtained.
