Light-emitting device, display device, and method for manufacturing the same

摘要

It is known that a light-emitting element utilizing organic EL deteriorates due to moisture. Therefore, a sealing technique to prevent moisture permeation is important. A light-emitting device including a light-emitting element utilizing organic EL is manufactured over a support substrate having flexibility and a high heat dissipation property (e.g., stainless steel or duralumin), and the light-emitting device is sealed with a stack body having moisture impermeability and a high light-transmitting property or with glass having moisture impermeability and a high light-transmitting property and having a thickness greater than or equal to 20 μm and less than or equal to 100 μm.
