Patent ID: 8120254

Claim:
A plasma display panel (PDP) comprising: a front panel including: a substrate on which display electrodes are formed; a dielectric layer covering the display electrodes; and a protective layer formed on the dielectric layer; and a rear panel disposed facing the front panel, such that a discharge space is formed between the front panel and the rear panel, the rear panel including address electrodes formed along a direction intersecting the display electrodes and including barrier ribs partitioning the discharge space, wherein the protective layer includes a primary film made of metal oxide and formed on the dielectric layer, wherein the protective layer includes a plurality of first particles and at least one type of a plurality of second particles, which is different from the plurality of first particles, wherein each of the plurality of first particles is in a lump form and comprises a plurality of metal oxide crystal particles piled up to form the lump form, and wherein the plurality of first particles and the plurality of second particles are dispersed on the primary film.
