    摘要： A plasma display device improved in efficiency and enhanced in image quality. This device has a pair of front and back substrates so opposed to each other and form discharge spaces partitioned by partition walls between the substrates, display electrodes arranged on the front substrate so as to form discharge cells between the partition walls, a dielectric layer so formed on the front substrate as to cover this display electrodes, and a phosphor layer which emits light by discharge between the display electrodes. The dielectric layer has structure of at least two layers with different permittivities, and a recess is formed for each discharge cell in the discharge space side surface of the dielectric layer, so that the discharge region is restricted to realize high-efficiency discharge. The structure of two layers with different permittivities enables suppression of crosstalk even if the thickness is decreased.

    摘要： An AC PDP (50) has a plurality of addressable subpixel sites, each subpixel site including an address electrode (52) positioned on one substrate (51) and first and second sustain electrodes (60, 62, 64) positioned on an opposed substrate (58). An intersection between the address electrode and the first sustain electrode defines a first discharge site and an intersection between the address electrode and the second electrode defines a second discharge site. A scan driver (70) is active during an address phase, and applies a negative going signal to the first sustain electrode. An address driver (53) applies an address signal to the address electrode which creates a discharge at the first discharge site and causes a discharge thereat which induces a wall voltage at the second discharge site in accordance with a determined subpixel value. A sustain driver (68) applies a sustain signal to both the first sustain electrode and the second sustain electrode and creates a 'ping pong' action of the wall charge states at the discharge sites and enables the use of positive column light emission in the PDP.
