Abstract: There are provided a plasma display panel and an imaging device which realize a high luminous efficiency, guaranteed long lifetime and stable driving. The plasma display panel 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 &mgr;s or less.

Abstract: A receiver includes two input terminals. A VHF broadcast signal over a 6-MHz band channel is inputted through one input terminal, while an FM broadcast signal over an approximate 100-kHz band channel is inputted through the other input terminal. The other input terminal is connected with a trap circuit for band width reduction. This trap circuit causes attenuation in signal components over channels close to a desired channel except that over the desired channel with a band of approximately 100 kHz. An analog switch inputs selectively the VHF broadcast signal and the FM broadcast signal attenuated in the signal components to a tuning circuit having a tuning band width of approximately 6 MHz. When an FM broadcast signal is selected, an FM broadcast signal only over a desired channel is outputted from the tuning circuit.
