Abstract: In a liquid crystal display device comprising a substrate which has an organic material film (e.g. a leveling layer, or an alignment film) and a conductive oxide film (e.g. an electrode) covering at least a part of the organic material film both formed on an inner surface thereof facing a liquid crystal layer, the present invention provides the conductive oxide film formed at a temperature being neither higher than a thermal decomposition temperature of the organic material film nor lower than a heat deflection temperature of the organic material film, so as to prevent blebs from foaming from the organic material film and appearing in the liquid crystal layer even after a long term storage of the liquid crystal display device or even external force applied to the liquid crystal display device.

Abstract: The irregularities of coloring concentration which is generated between dyed media when a color filter substrate which is prepared in a manufacturing method of a liquid crystal display device is manufactured by supplying ink to dyed media formed on a main surface of the color filter substrate using an ink jet method. In the present invention, as color filter ink which is supplied to the dyed media formed on the color filter substrate using the inkjet method, liquid which contains dye which colors the dyed media, solvent (for example, water) which has an affinity for the dye, a volatility-adjusting agent (for example, glycerin) which lowers the volatility of the ink to a level below the volatility of the solvent, and a dyeing-promoter agent (for example, N-methyl-2-pyrrolidone) which exhibits a higher affinity for the dye and the dyed media than the volatility adjusting agent. Then, the dyed media is colored with this ink.

Abstract: After forming a black matrix which defines pixel regions on a substrate, dyed substrate layers of photo hardening property are formed. By irradiating ultraviolet rays to the dyed substrate layers from the back of the substrate and by developing, ink reservoirs which use the black matrix as partition walls are formed. The dyeing material such as the dye is supplied to these ink reservoirs by an ink jet system. Due to these partition walls, there is no possibility that the dyeing material scatters to the neighboring or adjacent pixel regions to cause the mixed color. Further, since the filters having a sufficient thickness can be formed in the ink reservoirs, the surface flatness of the color filters can be sufficiently ensured without coating the thick overcoat layer.
