A plasma display device having improved efficiency and increased image quality. This device includes a pair of front and back substrates opposed to each other to form between the substrates a discharge space partitioned by barrier ribs, a plurality of display electrodes, each of which is formed of a scan electrode and a sustain electrode and disposed on the substrate of a front panel to form a discharge cell between the barrier ribs, a dielectric layer formed above the front substrate to cover the display electrodes, and a phosphor layer which emits light by discharge between the display electrodes. The dielectric layer is constructed of at least two layers of different softening points and is formed with, at its surface closer to the discharge space, a recessed part in each discharge cell. This suppresses extension of the discharge and allows stable formation of the recessed part. |
