Abstract

A plasma display panel and an imaging device realize a high luminous efficiency, a 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 electrode serving as an address electrode is 2 μs or less.

Claims8

Dependent claims

A plasma display panel comprising:

a discharge space;
a plurality of discharge electrodes including an electrode having a function of addressing;
said discharge space being filled with a discharge-gas mixture containing at least Xe, Ne and He;
and
a circuit which applies a voltage pulse to said electrode having a function of addressing, thereby producing a write-discharge in said discharge space,
wherein a Xe proportion of said discharge-gas mixture is in a range of from 2% to 20%,
a He proportion of said discharge-gas mixture is in a range of from 15% to 50%,
said He proportion being greater than said Xe proportion,
a total pressure of said discharge-gas mixture is in a range of from 400 Torr to 550 Torr, and
a width of said voltage pulse is 2 μs or less.
