A back sealing member for an organic electroluminescence device, capable of prolonging the life of the device, a glass substrate for an organic electroluminescence device, an organic electroluminescence device, and methods for manufacturing the sealing member and glass substrate. An organic EL device 10 comprises a soda-lime glass substrate 11 an organic EL laminate film 12 formed on one side of the glass substrate 11, a pair of organic EL drive pattern formation parts 13 formed on the surface of the glass substrate 11, in the peripheral area of the organic EL laminate film 12, and a back sealing plate 20 made of soda-lime glass, adapted for an organic EL device, and so bonded to the glass substrate 11 through an adhesive layer 14 that the organic EL laminate film 12 is accommodated inside and the organic EL drive pattern formation parts 13 are interposed between the adhesive layer and the back sealing plate. The glass substrate 11 has a dealkalized part 15 subjected to dealkalization on its outermost layer, and the back sealing plate 20 has a dealkalized part 21 subjected to dealkalization on its outermost layer. |
