PROBLEM TO BE SOLVED: To provide an MgO deposition material which is manufactured with excellent yield, can provide excellent discharge responsiveness over a wide temperature range, and enables the number of address IC to be considerably reduced without degrading panel luminance. SOLUTION: An MgO deposition material for forming a protection film for a PDP is composed of an MgO pellet having an MgO purity of≥98% and a relative density of≥90%. The pellet includes only Sc element as a rare earth element. Concentration of the Sc element is 5-5,000ppm, preferably, 10-3,000ppm, and more preferably, 20-2,000ppm. COPYRIGHT: (C)2006,JPO&NCIPI
