Title:
GAS−DISCHARGE PANEL AND ITS MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2002/099833
Kind Code:
A1
Abstract:
A gas−discharge panel which is drivable at high speed by low drive voltage while write errors in the write period hardly occurs and its manufacturing method are disclosed. An auxiliary gas containing at least one gas selected from a carbon dioxide gas, steam, an oxygen gas, and a nitrogen gas is fed into a discharge space (30) of a gas−discharge panel evacuated to a vacuum to a degree such that the pressure of the residual gas is 0.02 mPa or less, and thereafter an He−Xe or Ne−Xe rare gas (discharge gas) is fed. If a carbon dioxide gas is mixed, the amount of auxiliary gas fed into the discharge space (30) is set in consideration of both the discharge start voltage and electron emission power so that the partial pressure of the auxiliary gas is between 0.05 and 0.5 mPa.
