| 1. A plasma display device comprising:
a plasma display panel including a plurality of row electrode pairs which constitute display lines, a plurality of column
electrodes intersecting with said plurality of row electrode pairs, and display cells each formed at each of the intersections
of said row electrode pairs with said column electrodes, each of said display cells having a magnesium oxide layer including
magnesium oxide crystals which are excited by an electron beam to emit cathode luminescence light having a peak in a wavelength
range from 200 to 300 nm;
a row electrode driving circuit for driving each of said plurality of row electrode pairs; and
a column electrode driving circuit for driving each of said plurality of column electrodes, so that a halftone image is displayed
in a one-field display period which is divided into a plurality of sub-fields each of which includes an addressing period
and a sustain period,
wherein in said addressing period, said row electrode driving circuit applies a scanning pulse to one row electrodes of said
row electrode pairs in turn, while said column electrode driving circuit supplies said column electrodes with data pulses
corresponding to a display line which are applied with the scanning pulse.
