Abstract
A technology for PDP, etc. by which discharge delay improving effects can be enhanced over the prior art. In a representative embodiment, there is provided a process for manufacturing a PDP with a magnesium oxide (MgO) crystal layer (priming particle emitting layer) exposed in discharge space, the MgO crystal layer comprised of powder (grains) of MgO crystal, which process comprises performing thermal treatment of the MgO crystal in an oxygenous atmosphere. In particular, the thermal treatment is performed so that the lower limit of grain diameter of MgO crystal is 50 nm or greater.
