A plasma display panel (PDP) includes a first substrate and a second substrate opposing one another with a predetermined gap therebetween. The PDP also includes first electrodes formed on a surface of the first substrate opposing the second substrate, and second electrodes formed on a surface of the second substrate opposing the first substrate. Long axes of the first electrodes intersect those of the second electrodes. Also included in the PDP are dielectric layers. One dielectric layer is formed covering the first electrodes on the first substrate, and another dielectric layer is formed covering the second electrodes on the second substrate. There is further included an MgO protection layer that is formed covering the dielectric layer on the first substrate. A crystalline orientation planes of the MgO protection layer are produced by mixing (111) planes and (110) planes, and a mixing ratio of the (111) planes and the (110) planes is settled according to a grain size of the MgO protection layer.
