Abstract

PURPOSE:To obtain a seal material for an inexpensive fluorescent display tube free of degradation in display grade, by forming recessed parts and protruded parts of a seal member by half-etching, and performing coating of a fritted glass to each glass sheet. CONSTITUTION:An annular cut portion 4 is formed, by etching, in a 426 alloy plate 1 serving as a sealing member between two adjacent half-etched portions 3 and 3, and around a position corresponding to an exhaust hole formed in a glass substrate of a fluorescent display tube. Next, the surface of the 426 alloy plate 1 formed with the half-etched portion 3 and the cut portion 4 is oxidized, and a fritted glass 2 is coated, by screen-printing, into the half-etched portion 3, and then is baked, Then, the resulting alloy plate 1 is divided at the cut portion 4, to obtain seal member pieces. This enables reduction in the cost and also enables obtaining a fluorescent display tube of high display grade without scattering of part of the fritted glass 2 into the fluorescent display tube.
