1. A liquid crystal display device comprising, in each pixel area on a liquid-crystal-side surface of one of substrates disposed in opposition to each other with a liquid crystal interposed therebetween:

  • a thin film transistor to be driven by supply of a scanning signal from a gate signal line;

    a pixel electrode to be supplied with a video signal from a drain signal line via the thin film transistor; and

    a counter electrode which causes an electric field to be generated between the counter electrode and the pixel electrode, the counter electrode being formed in a layer overlying the pixel electrode with a stacked insulating film interposed between the counter electrode and the pixel electrode, the stacked insulating film being made of a stacked structure in which an insulating film including a part of a gate insulating film of the thin film transistor, an inorganic material layer and an organic material layer are stacked in that order, the counter electrode being made of a plurality of stripe-shaped counter electrodes which are disposed to be extended in one direction and to be juxtaposed in a direction transverse to the one direction, and the pixel electrode being made of a transparent plane-shaped electrode which is formed in a large part of the pixel area.
