Liquid crystal display device and manufacturing method thereof

A liquid crystal display device, comprising:

• a plurality of gate lines formed in a first direction on a substrate;
• a plurality of data lines formed in a second direction different from the first direction on the substrate;
• a plurality of first transparent common electrodes formed on the substrate;
• a plurality of transparent pixel electrodes arranged in the first direction and the second direction and formed so as to be opposed to the plurality of first transparent common electrodes;
• an insulating film formed between the plurality of first transparent common electrodes and the plurality of transparent pixel electrodes;
• a plurality of thin film transistors connected to the plurality of transparent pixel electrodes, respectively;
• and
• a second transparent common electrode formed on the surface of the insulating film,
• wherein the second transparent common electrode covers at least one of the plurality of gate lines and the plurality of data lines through the insulating film,
• the second transparent common electrode is formed in a same layer as the plurality of transparent pixel electrodes,
• a first transparent electrode material is disposed between the plurality of gate lines and the substrate, and
• the first transparent electrode material is formed in a same layer as the plurality of first transparent common electrodes.
