Abstract:
1. A liquid crystal display device comprising: liquid crystal sandwiched between a first substrate and a second substrate which face each other in an opposed manner; a plurality of gate lines which extend in the first direction and are arranged parallel to each other; a plurality of drain lines which extend in the second direction which crosses the gate lines and are arranged parallel to each other; a plurality of switching elements which are arranged at crossing portions of the gate lines and the drain lines; pixel electrodes which are driven by the switching elements are formed on an inner surface of the first substrate; wherein having an electrode forming layer which include the gate lines, the drain lines, the switching elements and the pixel electrodes, having a reference electrode layer arranged between the first substrate and the electrode forming layer with first insulation layer between the reference electrode layer and the electrode forming layer, and the electrode forming layer includes the gate insulation layer, the passivation layer and the pixel electrode in this order over the first insulation layer, and holding capacities of the pixels are formed among the pixel electrodes, the reference electrode layer and a capacitive electrode layer, wherein the capacitive electrode layer is formed over the passivation layer, and the capacitive electrode layer is connected to the reference electrode layer via through holes which penetrate the passivation layer, the gate insulation layer and the first insulation layer.
