Abstract

An organic EL panel has a light-emitting part including one or a plurality of organic EL elements over a substrate and having a sealing structure sealing the light-emitting part. The organic EL element includes an organic layer formed on a first electrode, and a second electrode formed on the organic layer. The organic EL panel includes a coating film coating the light-emitting part. A contact object is arranged on an inner surface of the sealing structure. One or a plurality of convex parts is formed on the contact object. The coating film is formed to have a thickness larger than the length of the convex part.

Claims
