Liquid crystal display device

A liquid crystal display device including a liquid crystal display panel, a back light and a light control panel set between the liquid crystal panel and the back light comprising:

• the light control panel comprises a first substrate, a second substrate and a liquid crystal layer between the first substrate and the second substrate,
• wherein a plurality of signal wirings, an insulating film covering the signal wirings, a first electrode formed in a planar shape on the insulating film, an interlayer insulating film covering the first electrode, and a second electrode on the interlayer insulating film are formed on a surface facing to the liquid crystal layer of the first substrate,
• the signal wiring and the first electrode are connected via a through hole formed in the insulating film,
• the signal wiring is made of a first transparent conductive film, the first electrode is made of a second transparent conductive film, the second electrode is made of a third transparent conductive film,
• a dummy wiring made of a same material as the first transparent conductive film is formed on a layer that the signal wirings are formed, and
• the second electrode is between the signal wirings in a plan view.
