Abstract:
A process for producing a plasma display panel having a first and second glass substrate, wherein each substrate comprises a planar surface, and said planar surface of the first substrate is opposed in parallel to said planar surface of the second substrate, said process comprising the steps of:depositing a seal on said surface of at least one of the glass substrates wherein the seal is epoxy or polyvinyl butyrate; placing the first and second substrates over one another with the seal interposed therebetween to form a seal and a glass substrate assembly; curing the seal to fasten the glass substrates to each other and to form a space between the glass substrates within the cured seal; vacuum pumping the space; filling the space with a discharge gas via a means of access; and sealing the means of access, wherein the curing step comprises maintaining the seal and glass substrate assembly for about 30 to 60 minutes at a temperature of between 200Â° to 300Â° Centigrade.
