    摘要: A method of forming a metal line is provided. A first metal layer and a second metal layer protecting the first metal layer are formed on a base substrate. The first metal layer includes aluminum or aluminum alloy. A photoresist pattern having a linear shape is formed on the second metal layer. The first and second metal layers are dry-etched using etching gas and the photoresist pattern as an etching mask. An etching material is removed from the base substrate, to prevent corrosion of the dry-etched first metal layer. Therefore, the source metal pattern without corrosion may be formed through a dry-etching process so that a manufacturing cost is decreased.
