ABSTRACT:
A liquid crystal display device includes first and second opposed facing substrates and liquid crystal sandwiched therebetween. The first substrate includes a thin film transistor having a first electrode thereof connected to a video signal line and a second electrode thereof connected to a pixel electrode, a first silicon nitride film, an organic insulation film, a capacitance electrode, and a second silicon nitride film. The second silicon nitride film is formed at a temperature lower than a forming temperature of the first silicon nitride film. The second electrode and the pixel electrode are connected to each other via a contact hole formed by the first and second silicon nitride films. A potential different from a potential applied to the pixel electrode is applied to the capacitance electrode, and a holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.
