We have studied the characteristics of the application of a high-gamma cathode material to a plasma display panel (PDP) for the improvement of the secondary electron emission property and consequent luminous efficacy. It had been found that the PDP with the MgCaO cathode layer and the SiO 2 diffusion barrier, which can block the impurity diffusion from the underlying dielectric layer, is stable during the normal fabrication process and showed improved luminous efficacy at a lower sustain voltage compared with those of the conventional PDP with MgO.
