摘要： Phosphor layers (110G, 110B, and 110R) are made of a combination of: blue and green phosphors that are positively charged on their surfaces and baked in an oxygen-nitrogen atmosphere to reduce oxygen vacancy, and that have a β-alumina crystal structure; and a red phosphor made of an yttrium oxide compound. Uniformly forming such phosphor layers on the wall surfaces of barrier ribs (109) provides equal charge characteristics of the phosphors of respective colors, reduces oxygen vacancy in the phosphors, and inhibits adsorption of various gases in the panel production process. This can stabilize the discharge characteristics and prevent luminance degradation at driving the panel.
