Abstract
A plasma display includes a rear substrate, a plurality of first electrodes formed in strips and parallel to each other on an inner surface of the rear substrate, a dielectric layer coated on the rear substrate to cover the first electrode, a plurality of partitions formed in strips on the dielectric layer, defining a discharge space, a fluorescent layer coated on an inner surface of the discharge space, a front substrate which is transparent and coupled above the partitions, second and third electrodes formed in strips and to be parallel to one another on an inner surface of the front substrate and to cross the first electrode, and a black matrix formed between a discharge cell constituted by a pair of the second and third electrodes and another discharge cell adjacent thereto, by filling a groove which is formed at the inner surface of the front substrate to be parallel to the second and third electrodes with a light shielding material.
