Abstract: In a method of manufacturing a liquid crystal display device, a process for forming a first substrate includes the steps; forming a first wiring electrically connected with a switching element and extending in a first direction, forming an insulating film covering the first wiring, painting an electrically conductive film including electrically conductive material on the insulating film, and forming a second wiring electrically connected with the switching element extending in a second direction orthogonally crossing the first direction, and a pixel electrode electrically connected with the switching element apart from the second wiring by patterning the electrically conductive film. A second substrate is formed by forming a main common electrode extending in the second direction. A liquid crystal display panel is manufactured by holding liquid crystal material between the first substrate and the second substrate while the main common electrode faces the second wiring.
