摘要： A liquid crystal display panel is provided and includes substrates opposed to each other with a liquid crystal layer interposed therebetween, one of the substrates including gate and common lines disposed in parallel, source lines intersecting the gate and common lines, and switching elements in the vicinities of intersections of the gate and source lines. A lower electrode of a transparent conductive material and an upper electrode with slits are stacked with an insulating film interposed therebetween for each area defined by the gate and source lines. The upper electrode and the lower electrode are electrically connected to the corresponding switching element and the corresponding common line, respectively. The insulating film has a multi-layered structure of first and second insulating films close to the substrate and the liquid crystal layer, respectively. The surface of the lower electrode is covered with the first insulating film. The gate and common lines are formed on the surface of the first insulating film. The common line is electrically connected to the lower electrode via a contact hole formed in the first insulating film.
