ABSTRACT:
The invention prevents a desiccant layer in an organic EL display panel from peeling off and enhances reliability in resistance to a temperature cycle. A device glass substrate is attached to a sealing glass substrate for sealing devices with sealing resin made of epoxy resin etc. The sealing glass substrate is formed with a pocket portion by etching. An Al layer having a thickness of about 4000 Å is formed on a bottom of the pocket portion by an evaporation method, serving as a stress buffering layer. A desiccant layer for absorbing moisture is coated on the Al layer.
