摘要： An aging drive method for a thin film EL panel includes the performing a preparatory step of short-circuiting all transparent electrodes by a first connecting line, short-circuiting every other metal electrodes by a second connecting line and short-circuiting the other metal electrodes by a third connecting line. Thereafter four fields are repeatedly periodically executed for a specified period of time to thereby cause all picture elements of the panel to luminesce for aging. Each of the four fields includes a first step of applying a first voltage across the first and second connecting lines and across the first and third connecting lines to charge all the picture elements. Further a second step is included of applying a second voltage across the second and third connecting lines while holding the transparent electrodes in a floating state. This causes luminescence of the picture elements of the metal electrodes short-circuited by the second or third connecting line, with the voltage resulting from the charge on the picture elements stored in the first step and with the second voltage. The four fields are different from one another in the combination of the polarities of the first and second voltages.

摘要： At least one silicon-oxynitride film is deposited on an electroluminescence layer for providing a uniform and stable dielectric layer for an electroluminescence display panel. The silicon-oxynitride film is deposited using a sputtering technique by mixing a small amount (1 mol%) of nitrous oxide (N.sub.2 O) gas into a sputtering gas such as nitrogen (N.sub.2) gas. Oxygen (O.sub.2) gas may be substituted for the N.sub.2 O gas mingled within the sputtering gas in the amount of five mol%. A target for sputtering is a pure silicon or sintered Si.sub.3 N.sub.4 plate. An R.F. discharge is provided so that the power flux density on the target becomes several to several ten W. The silicon-oxynitride film is derived by means of the reaction between ion sputtering and the sputtering gas. A dielectric layer is further provided for establishing high reliabiltiy high dielectric properties of the electroluminescence display panel, the dielectric layer being disposed together with the silicon-oxynitride film and being one of the group consisting of Al.sub.2 O.sub.3, SiO.sub.2, Ta.sub.2 O.sub.5, Si.sub.3 N.sub.4 and Y.sub.2 O.sub.3. The silicon-oxynitride flm which is injected by suitable ions such as P.sup.+, H.sup.+, He.sup.+, Ne.sup.+, or Ar.sup.+ may be further provided as the dielectric layer.

摘要： When driving a thin-film EL display panel having groups of two electrodes on opposing sides of a thin-film EL layer, a voltage is applied so that the polarity of the AC pulse applied to the intersection (picture element) of opposing electrodes is the reverse of the polarity of the AC pulse applied simultaneously or nearly simultaneously to adjacent or nearly adjacent picture elements. This drive method avoids flicker caused by differing luminance intensities resulting from alternating polarity in EL matrix-type displays.

摘要： At least one light-absorption layer is disposed between a thin electroluminescent film and a counter electrode for absorbing light applied through a transparent electrode. According to the light-absorption layer, less light is reflected by the counter electrode, thereby preventing a visual contrast provided by electroluminescence from lowering owing to the reflected light. A plurality of light-absorption layers may be formed in the same arrangement. Materials useful for the light-absorption layers are Al.sub.2 O.sub.3, Al.sub.2 O.sub.3-x, Mo, Zr, Ti, Y, Ta, Ni, Al or the like with a thickness of about 10-300 A.

摘要： A thin film EL display device is described which comprises a group of parallel scanning electrodes, a group of parallel data electrodes laid so as to extend perpendicular to the group of the scanning electrodes, and an EL layer disposed between the respective groups of the scanning and data electrodes. Each of the electrodes of at least one of the groups of the scanning and data electrodes which apply a writing voltage to the EL layer is connected with a driver circuit of high voltage breakdown characteristic having only a push-pull function or a pull-up and pull-down function. This driver circuit employs thyristors as switching elements.
