ABSTRACT:
In the present liquid crystal display device, a switching element, a data line connected to one end of the switching element, and an interconnecting wire insulated from the data line are formed on a substrate. The switching element, the data line, and the interconnecting wire are covered with an interlayer insulating film. An auxiliary capacitor electrode made of reflective metal and connected to the interconnecting wire is formed on the interlayer insulating film. An upper insulating film is formed on the interlayer insulating film to cover the auxiliary capacitor electrode, and a pixel electrode connected to the other end of the switching element is formed on the upper insulating film. The interconnecting wire is made of a material different from the auxiliary capacitor electrode, and the interlayer insulating film and upper insulating film have a contact hole which reaches the interconnecting wire.
