MANUFACTURING METHOD OF PLASMA DISPLAY PANEL, MANUFACTURING METHOD OF PLASMA DISPLAY AND PLASMA DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To reduce cost by improving productivity and reducing discharge starting voltage, to stabilize a display operation by improving the luminance of a plasma display panel.;SOLUTION: Front face substrate and back face substrate bonded together are arranged in a heating furnace. Heating is started while starting evacuation in a discharge space, and introduction of reducing gas is started to fill in the discharge space when the temperature T reaches 300-400 °C. Exhaustion of the reducing gas is started after the prescribed time elapses from the introduction of reducing gas. Magnesium oxide existing on a surface in the panel, especially, in a surface layer of a protective film is removed by introduction and exhaustion of the reducing gas. Then, oxidizing gas is introduced and filled in the discharge space 13. Exhaustion of the oxidizing gas is started after the prescribed time elapses from the introduction of the oxidizing gas. Hydride and carbon existing on the surface in the panel, especially, in the surface layer of the protective film 6 due to introduction of the reducing gas are removed by introduction and exhaustion of the oxidizing gas.;COPYRIGHT: (C)2005,JPO&NCIPI
