PURPOSE: A rear plate is provided to achieve improved electrical and optical characteristics by attaching a green tape of slurry to the upper surface of an electrode. CONSTITUTION: A rear plate(100) comprises a glass substrate(110); an electrode(120) formed on the glass substrate; a dielectric layer(130) formed on the electrode; barrier ribs(140) formed on the dielectric layer through an etching process; and a phosphor layer(150) formed along the side and bottom surfaces of barrier ribs. The electrode is formed into a thickness of 2 to 8μm. The dielectric layer is produced from a material consisting of PbO 30 to 80 weight% : ZnO 0 to 20 weight% : SiO2 0 to 20 weight% : B2O3 5 to 40 weight%: Al2O3 0 to 12 weight%: Na2O+K2O+Li2O 0 to 5 weight%: BaO+CaO+MgO+SrO 0 to 5 weight%. The barrier rib is produced from a material consisting of ZnO 0 to 48 weight% : SiO2 0 to 21 weight%: B2O3 25 to 56 weight% : Al2O3 0 to 12 weight% : Na2O+K2O+Li2O 0 to 38 weight% : BaO+CaO+MgO+SrO 0 to 15 weight%. The phosphor layer has a thickness of 10 to 50μm. The difference of coefficients of thermal expansion between the dielectric layer and the barrier rib is 0 to 10%, and the difference of softening temperatures between the dielectric layer and the barrier rib is 0 to 20 Deg.C.
