Liquid crystal display device, display device and manufacturing method thereof

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 further includes a capacitive electrode layer which is connected to the pixel electrodes between the first insulation layer and the passivation layer, and
• holding capacities of the pixels are formed among the pixel electrodes, the reference electrode layer and the capacitive electrode layer.
