Abstract
There are provided a plasma display device in which dark contrast can be enhanced without deteriorating an image quality and a method of driving a plasma display panel. In a case of driving a plasma display device in which a magnesium oxide layer containing a magnesium oxide crystal to be excited by the irradiation of an electron beam and performing a cathode luminescence having a peak in a wavelength range of 200 to 300 nm by a sub-field method, in order to initialize all display cells, reset discharge is caused in each of the display cells in M sub-fields of N consecutive sub-fields (0<M<N).
