ABSTRACT:
A liquid-crystal display device is provided wherein large electrostatic capacitance can be obtained without exposure of a metal film on a surface of a TFT array substrate, and yield in production and stability in images are improved. In the liquid-crystal display device of the present invention, a thin-film transistor section is mounted which is used to selectively connect either of a data wiring formed on a gate insulating film or a transparent electrode by a gate connected to an address wiring placed in each of picture element areas. In each of picture element areas, a capacitor section is formed with a first electrode formed, on the gate insulating film, using the same conductive film as used for the data wiring and a second electrode formed, on an upper layer insulating film formed on the gate insulating film, using the same transparent conductive film as used for a transparent electrode.
