Abstract
A plasma display panel capable of realizing improvement in the characteristics thereof, such as lower discharge voltage, more stable discharge, higher luminance, higher efficiency, and longer life. During a step of sealing the periphery of substrates or before this sealing step, impurity gas other then inert gas is adsorbed by phosphor layers. The impurity gas is released into discharge gas and the impurity is added to the discharge gas in a controlled manner while the panel is lit. This method can realize improvement in characteristics, such as lower discharge voltage, higher luminance, higher efficiency, and longer life.
