<p>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.</p> |
