Abstract
A plasma display apparatus and a driving method of a plasma display panel which can improve a gradation expressing ability at low luminance. A magnesium oxide layer containing a magnesium oxide crystal which is excited by irradiation of an electron beam and performs a cathode luminescence light emission having a peak in a wavelength range of 200 to 300 nanometers is provided in each of display cells formed on the plasma display panel. When driving for a plurality of subfields having different luminance weights is performed, a sustaining discharge is caused only once in the subfield having the minimum luminance weight.
