There are provided a plasma display panel (100) and an imaging device (102) which realize a high luminous efficiency, guaranteed long lifetime and stable driving. The plasma display panel (100) uses a discharge-gas mixture containing at least Xe, Ne and He. A Xe proportion of the discharge-gas mixture is in a range of from 2 % to 20 %, a He proportion of the discharge-gas mixture is in a range of from 15 % to 50 %, the He proportion is greater than the Xe proportion, and a total pressure of the discharge-gas mixture is in a range of from 400 Torr to 550 Torr. A width of a voltage pulse to be applied to an address electrode is 2 mu s or less. <IMAGE>
