Abstract
For use in a display device, a simple-matrix-drive-type luminescent panel is formed by stacking a dielectric mirror layer, a transparent electrode, a hole transport layer, a luminous layer, and a metal electrode on a glass substrate, wherein the transparent electrode is formed as a plurality of stripes equally spaced apart a specified distance from each other, and the metal electrode is formed as a plurality of stripes equally spaced apart a specified distance from each other and arranged at right angles with the transparent electrode stripes, and pixels are formed at intersections of the metal electrodes and the transparent electrodes and wherein in order for the pixels of the panel to emit light to display information, the application of a voltage to the pixels is controlled by selection of the electrodes according to information. This luminescent panel contributes to reductions in size and weight of the display device.
