Abstract
A plasma display device comprises display electrodes that are opposingly formed for each display line on a front substrate with a discharge gap interposed, a dielectric layer formed in a manner covering the display electrodes, and a phosphor layer that emits light due to discharge between the display electrodes. At least one recess is formed on a surface of each of discharge cells on a side of a discharge space of the dielectric layer, and discharge electrodes that constitute the display electrodes are formed in a manner projecting out toward a discharge gap so that they face each other with the discharge gap interposed in a bottom region of the at least one recess.
Claims20
A plasma display device comprising:
- a front substrate and a back substrate positioned so as to define a discharge space therebetween;
- ribs between said front and back substrates so as to divide the discharge space;
- two display electrodes, each of said two display electrodes including a discharge electrode on said front substrate and a bus electrode for supplying power to said discharge electrode, with each said discharge electrode projecting from a corresponding said bus electrode so as to define at a displaying line a discharge gap between said discharge electrodes, whereby a discharge cell is defined between said two display electrodes and two corresponding adjacent ones of said ribs;
- a dielectric layer covering said two display electrodes;
- and
- two recesses in a portion of a surface of said dielectric layer corresponding to said discharge cell, with one of said discharge electrodes being at a bottom region of one of said two recesses and the other of said discharge electrodes being at a bottom region of the other of said two recesses.
