Gas discharge display
 The present case relates to a gas discharge display, represented with a plasma display panel(PDP), for displaying an image by displaying gradation using a discharge characteristic of a particular gas. Of a background art gas discharge display for displaying an image by means of a gas discharge having transparent front, and back substrates supported by barrier ribs of a fixed length from inside thereof, electrodes, dielectric, and protective film provided inside of the front, and back substrates, and Penning gas of two gases (Ne+Xe, He+Xe, and etc.) or Penning gas of three gases (Ne+Xe+Ar, He+Xe+Ar, Ne+Xe+He) filled in spaces of the two protective films as a discharge gas, a Penning gas of four gases (Ne+He+Xe+Ar) is used in the gas discharge display for improving a luminance. Accordingly, by using the Penning gas of four gases, this case can satisfy a longer life time, a lower discharge starting voltage, a higher luminance, and an improved color purity in comparison to a CRT display on the same time, thereby allowing realization of a next generation wall mounting large sized display.
