Abstract:
A method of manufacturing a gas discharge panel having a pair of substrates sealed together with a sealant and defining a discharge space therebetween, comprising:forming the sealant in a frame-shape on at least one of the pair of substrates, and stacking said substrates, one upon the other via the sealant; lowering a pressure in the discharge space between the pair of substrates before the sealant starts to melt, relatively to a pressure on an exterior of the pair of substrates, by starting an exhausting operation to exhaust the discharge space via a through hole provided in one of the pair of substrates, while heating and thereby melting the sealant and introducing gas being exterior to the pair of the substrates so as to remove an impurity in the discharge space; solidifying the sealant so as to fixedly join the pair of substrates with the discharge space therebetween; exhausting the discharge space; and filling a discharge gas into the discharge space.
