A sealing glass substrate that allows control of adhesion width and ready cutting of the glass substrate without extending the cutting position in a process of manufacturing organic EL displays by sealing and cutting an organic EL substrate containing one or more organic EL (electroluminescent) display parts. The sealing glass substrate seals an organic EL substrate that includes one or more organic EL laminates. The sealing glass substrate is formed of a glass plate and includes one or more recesses each opposing one of the organic EL laminates. An adhesion region surrounds each recess, and an adhesion escape groove surrounds each adhesion region. The recesses and adhesion escape grooves are of substantially equal depth.
