Abstract
In a plasma display device comprising a pair of opposing insulating substrates and a plurality of light emitting cells formed from partition walls which divide the space between the insulating substrates while a plurality of electrodes are formed in the light emitting cells and the inner space is filled with a discharge gas and plasma being generated by applying a voltage selectively between the electrodes so that the fluorescent substances formed on the inner walls of the light emitting cells emit light as light emitting elements, wherein sizes of the light emitting cells of different colors are made different according to the luminance of the fluorescent substance of the corresponding color. That is, cells which emit light of a color of luminance lower than the other cells are made with larger opening to obtain equally high luminance for all the three primary colors, thereby mitigating the deviation in the luminance among the fluorescent substances and achieving full-color display of high image quality with high color purity.
