Abstract: PURPOSE: A method for forming a pixel electrode of a liquid crystal display device is provided to increase an etching ratio of an ITO film and pattern the ITO film according to a dry etching process, thereby improving yield considerably. CONSTITUTION: The first insulating film(31) is deposited on a transparent substrate(30). The second insulating film(32) is formed on the whole surface of the first insulating film(31). In general, the first and second insulating films(31,32) consist of silicon nitride films. An indium tin oxide(ITO) film(34) and a photoresist film are sequentially deposited on the second insulating film(32). Thereafter, a photoresist film pattern(36) is formed by etching the photoresist film. The exposed surface of the ITO film(34) is H2 plasma-processed by using the photoresist pattern(36) as a mask. Here, an active gas such as hydrogen and an inactive gas such as argon and nitrogen may be used as the plasma gas. When the active gas is employed in the pre-processing, internal composition of an object film is varied to weaken bonding of the object film. When the inactive gas is used in the pre-processing, bonding of the object film is physically weakened. It serves to improve an etching ratio in an etching process. As a result, the ITO film is etched according to the dry etching process, which results in an improved yield.
