Abstract:
1. A method of manufacturing a plurality of organic electroluminescent display devices comprising: preparing a rear substrate having a plurality of organic electroluminescent portions; coating a mixture comprising a polymer, a silicate, and solvent on an entire internal surface of a front substrate; aging the mixture after coating; curing the mixture so that the polymer is burnt, whereby the mixture is formed to a porous silica layer; coating a sealant on the mixture and on portions outside the plurality of electroluminescent portions disposed on at least one of the rear substrate and the front substrate; assembling the rear substrate and the front substrate, thereby forming a panel having a plurality of organic electroluminescent display devices; and cutting the panel to manufacture the plurality of organic electroluminescent display devices, wherein the porous silica layer covers the entire internal surface of the front substrate after cutting the panel.
