PURPOSE: An in-plane switching liquid crystal display is provided to reinforce the strength of an electric field between a data electrode and a common electrode and reduce a drive voltage applied to a liquid crystal, by forming a passivation film on an active element while forming no passivation film on a pixel region. CONSTITUTION: A gate electrode(110) is formed on a substrate(103) and is connected to a gate wiring A gate insulator(113) is formed on the gate electrode(110), and an active layer(115) is formed on the gate insulator(113). An n+ layer(116) is formed on the active layer(115). Source and drain electrodes(117,118) are formed on the n+ layer(116) and are connected to a data wiring and a data electrode(119), respectively. A common electrode(111) is formed on the first substrate, and the data electrode(119) is formed on the gate insulator(113) and connected to the drain electrode(118). The elements(110,113,115,116,117,118) form a thin film transistor. A passivation film(120) is stacked on the thin film transistor, and the first polymide is deposited on an entire surface of the substrate(103).
