ABSTRACT:
A plasma display panel is composed of a first substrate and a second substrate facing each other via a discharge space and sealed together. A protective layer on the first substrate is composed principally of magnesium oxide, includes a substance or structure that creates a first energy level in an area of a forbidden band, the area being in a vicinity of a conduction band, and includes a substance or structure that creates a second energy level in another area in the forbidden band, the other area being in a vicinity of a valence band. During driving the second energy level is occupied by electrons, and few electrons exist in the first energy level, or electrons can easily occupy the first energy level due to a minus charge state, and MgO insultaive resistance is not lowered. This maintains wall charge retention and reduces discharge irregularities and firing voltage Vf.
