Patent ID: 7528548

Claim:
A plasma display panel, which is equipped with a front substrate and a back substrate placed opposite each other on either side of a discharge space, a plurality of row electrode pairs provided between the front and back substrates, and column electrodes extending in a direction at right angles to the row electrode pairs between the front and back substrates and forming unit light emission areas respectively corresponding to intersections with the row electrode pairs in the discharge space, the unit light emission areas being divided into three types, red unit light emission areas in which red phosphor layers are formed, green unit light emission areas in which green phosphor layers are formed and blue unit light emission areas in which blue phosphor layers are formed, a discharge being initiated in each of the unit light emission areas by applying voltage between the row electrodes constituting each row electrode pair or between the column electrode and the row electrode, the plasma display panel comprising a crystalline magnesium oxide layer that includes magnesium oxide crystals capable of emitting a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm , and is provided between the front substrate and the back substrate, facing the red unit light emission areas, the green unit light emission areas and the blue unit light emission areas, wherein any one of the phosphor layers of the red, green and blue colors has a material capable of effecting a change in an electrification property of the phosphor layer for giving rise to an approximate match between a timing of a discharge initiated in the green unit light emission area and a timing of either a discharge initiated in the red unit light emission area or that initiated in the blue unit light emission area.
