Abstract:
1. A liquid crystal display device comprising a TFT substrate, a counter substrate and liquid crystal sandwiched between the TFT substrate and the counter substrate, wherein support columns which project toward the TFT substrate are formed on the counter substrate, a plurality of gate signal lines, a plurality of drain signal lines, thin film transistors, an insulation film which covers the thin film transistors, organic films which are arranged on the insulation film, and a transparent electrode which constitutes a common electrode arranged on an upper layer of the organic films are formed on the TFT substrate, a metal film which constitutes a common electrode auxiliary line is arranged on an upper layer of the transparent electrode, the insulation film, the organic films, the transparent electrode, and the metal film are laminated in this order on the gate signal lines, and portions of the metal film arranged on the upper layer of the transparent electrode form pedestals corresponding to the support columns, the portions of the metal film forming the pedestals being electrically insulated with respect to the metal film of the common auxiliary line.
