Patent number: 7002297
Abstract: To provide a technique for relatively easily preventing yellowing of a PDP that uses silver electrodes, and a PDP utilizing the technique that is capable of displaying images with high luminance and high quality. To form the electrodes, an alloy composed of Ag as a main constituent and a transition metal (at least one selected from Cu, Cr, Co, Ni, Mn, and Fe) is used, or an oxide of such a transition metal is added. Alternatively, an alloy composed of Ag as a main constituent and a metal (at least one selected from Ru, Rh, Ir, Os, and Re) is used, or an oxide of such a metal is added. Alternatively, Ag particles whose surfaces are each coated with a metal (Pd, Cu, Cr, Ni, Ir, or Ru) or a metal oxide (SiO2, Al2O3, NiO, ZrO2, Fe2O3, ZnO, In2O3, CuO, TiO2, or Pr6O11) are used.
