PURPOSE: An in plane switching mode LCD is provided to enable an electric current to flow regularly in case a power supply of a data electrode is suspended by forming a semiconductor layer between common wiring and a data electrode. CONSTITUTION: A gate insulation film(130) is formed on common wiring(119) and a-Si layer(131), n-plus layer(132) and a data electrode(120) are formed on the gate insulation film in order. Common wiring is made with depositing and etching Al, Ta, Mo, Cr through a sputtering method. The gate insulation film(130) is made with depositing an inorganic substance on a whole substrate through a CVD method. The a-Si layer(131) and the n-plus layer(132) are made with etching an amorphous silicon(a-Si) and n-plus a-Si and are formed in a whole area under a data electrode.
