Abstract
A plasma display device having improved luminous efficiency 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 discharge space is filled with mixed gas as discharge gas, the mixed gas includes Xe having a partial pressure of 5% to 30%, and the dielectric layer is formed with, at its surface closer to the discharge space, a recessed part in each discharge cell.
