PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE

A PDP is provided with a front plate and a rear plate. The front plate has a protective layer. The protective layer includes a base layer, a plurality of first particles and a plurality of second particles. The first particles are aggregated particles obtained by aggregating a plurality of crystal particles made of magnesium oxide and having a cathode luminescence peak in a wavelength region from 200 nm or more to 300 nm or less. The second particles are crystal particles made of magnesium oxide, which have a cathode luminescence peak in a wavelength region from 400 nm or more to 450 nm or less, but do not have a cathode luminescence peak in the wavelength region from 200 nm or more to 300 nm or less.
