ABSTRACT:
A technique for sealing an EL panel of a light emitting device is provided. By preparing a absorption metal as a film on EL elements on the inside of an enclosed space, it becomes easy to made the interior of the space possess a absorption function, and further, an enclosure structure can be fabricated without the penetration of oxygen and moisture into the space because the absorption film is formed in succession after formation of the EL elements, according to the present invention.
