Abstract

(57)【要約】 【課題】ハレーションの発生を防ぎ、表示品位の高いプ ラズマディスプレイ用部材を提供することを目的とす る。 【解決手段】基板上に少なくとも電極層、誘電体層A、 誘電体層B、隔壁および蛍光体層を順次積層した部材で あって、該誘電体層Aが光学濃度(OD値)0.5以上 の黒色層、該誘電体層Bが全光線反射率40%以上の白 色層であることを特徴とするプラズマディスプレイ用部 材。
PROBLEM TO BE SOLVED: To prevent the occurrence of halation, and to provide a high display grade by successively forming a dielectric layer A composed of a black layer having specific optical density and a dielectric layer B composed of a white layer having the specific total light beam reflectance on a board. SOLUTION: A plasma display member is manufactured by successively forming at least an electrode layer, a dielectric layer A composed of a black layer having optical density (an OD value) not less than 0.5, a dielectric layer B composed of a white layer having the total light beam reflectance not less than 40%, a barrier plate and a phosphor layer on a base material. The dielectric layer A contains glass having a glass transition point of 400 to 550°C and a softening point of 400 to 600°C by 50 to 98 wt.% and a black pigment by 2 to 50 wt.%. The dielectric layer B contains glass having a glass transition point of 450 to 550°C and a softerning point 500 to 600°C by 50 to 90 wt.% and a white filler by 10 to 50 wt.%, and the average particle size of the white filler is set to 0.15 to 5.00 μm. The thickness total of the dielectric layers A, B is desirably about 1.1 to 5.0 times a thickness of the electrode layer. COPYRIGHT: (C)2000,JPO
