Abstract
A semiconductor layer of a transistor is formed of an oxide semiconductor film including a crystal part. An organic resin film covering the transistor is formed. By treatment such as drying treatment on the organic resin film in a cell process, variations in the threshold voltage of the oxide semiconductor transistor due to moisture can be suppressed. A common electrode faces a pixel electrode. The common electrode and the pixel electrode are formed over the organic resin film with an insulating film provided therebetween. Therefore, a capacitor can be provided to a liquid crystal element if a pixel does not include a wiring for a storage capacitor. An antistatic electrode is provided on the outer side of a color filter substrate and the capacitance between the antistatic electrode and the common electrode is utilized, so that the liquid crystal display device can be used as a touch panel.
