ABSTRACT:
A matrix-addressed type display device has display material sandwiched between two substrates facing each other, and a transparent pixel electrode disposed in matrix arrangement. The display device display characters by the application of a voltage selectively to the transparent pixel electrode by the use of a thin-film transistor. To improve display characteristics, an electric charge capacitor is provided in each pixel. This electric charge capacitor is connected to an adjacent gate electrode path and includes a transparent inner bottom electrode sandwiched between a dielectric substrate and a transparent pixel electrode. A transparent dielectric film is Interposed between the transparent pixel electrode and the transparent inner bottom electrode.
