Plasma display device

A plasma display device for displaying an image on a plasma display panel in accordance with an input video signal, said plasma display panel having a plurality of row electrode pairs, a plurality of column electrodes intersecting with said plurality of row electrode pairs and forming display cells at the intersections, respectively, and a display period for one field of the input video signal is configured of a plurality of subfields each formed of an address period and a sustain period for the image display, said plasma display device comprising:

• a magnesium oxide layer formed at a portion facing said discharge space in each of said display cells, having magnesium oxide monocrystals which are excited by irradiating an electron beam to emit cathode luminescence light having a peak within a wavelength range of 200 to 300 nm, and which have a particle diameter of 2000 angstroms or greater;
• an address portion which selectively generates address discharge in each of said display cells in accordance with pixel data based on the video signal in the address period;
• a sustain portion which applies a sustain pulse between row electrodes forming each of said row electrode pairs in said sustain period;
• and
• a reset portion which applies a reset pulse between the row electrodes forming said row electrode pair before the address period for at least one subfield in one field of a display period in order to generate reset discharge in all of said display cells,
• wherein said sustain portion includes:
• a first transition portion which makes resonance transition of a potential of a row electrode of each of said row electrode pairs from a first potential to a second potential;
• a clamp portion which clamps the potential of said row electrode to said second potential;
• and
• a second transition portion which makes resonance transition of the potential of said row electrode from said second potential to said first potential, and
• wherein a first step of making transition from said first potential to said second potential, a second step of clamping to said second potential, and a third step of making transition from said second potential to said first potential are sequentially implemented in order to generate said sustain pulse, and
• in said sustain period for each of the subfields, a time point to clamp to said second potential at least one sustain pulse belonging to a first group including a sustain pulse to be first applied is delayed comparing to a time point to clamp to said second potential a sustain pulse belonging to other groups.
