Patent ID: 8045109

Claim:
A method of manufacturing a liquid crystal display device comprising a liquid crystal display panel and a backlight unit to transmit light on a display surface side of the liquid crystal display panel, wherein the liquid crystal display panel has a structure in which a display electrode and a reference electrode are provided on a surface of a region corresponding to a unit pixel on a liquid crystal layer side of one transparent substrate or each of both transparent substrates among the transparent substrates provided facing to each other via the liquid crystal layer, and light transmitting the liquid crystal layer is modulated by electric field generated parallel to the transparent substrate between the reference electrode and the display electrode to which a picture signal is supplied from a picture signal line via at least a switching element, wherein the transparent substrate situated on a remote position side with respect to the backlight unit among the transparent substrates in the liquid crystal display panel is the transparent substrate on a side of a position where no switching element is formed, and has a transparent conductive layer exhibiting optical transparency on a surface side opposite the liquid crystal layer of the transparent substrate, and the method of manufacturing a liquid crystal display device comprising: forming the transparent conductive layer in at least a pixel region by an atmospheric pressure plasma method employing at least nitrogen gas as a thin film forming gas; and operating the liquid crystal display panel having a structure in which a display electrode and a reference electrode are provided on a surface of a region corresponding to a unit pixel on a liquid crystal layer side of one transparent substrate among the transparent substrates provided facing to each other via the liquid crystal layer with an in-plane switching system by which light transmitting the liquid crystal layer is modulated by electric field generated parallel to the transparent substrate between the reference electrode and the display electrode to which a picture signal is supplied from a picture signal line via at least a switching element.
