ABSTRACT:
A panel-shaped gas-discharging type display device includes an anode and a cathode having a special shape to enhance discharging in an airtight chamber formed by two substrates. A gas containing an ultraviolet emission gas such as Xe and Kr and a fluophor for emitting a light are put together into the airtight chamber. Because of the shape of the cathode, more discharging occurs than with conventional devices. More ultraviolet emission from the discharging excites the fluophor to create a visible radiation. Therefore, the brightness of the device increases. Since the cathode is coated with an emitter material incapable of absorbing the ultraviolet emission gas, discharging is not obstructed by reduction of the ultraviolet emission gas, and the color of the visible radiation is stably maintained.
