Patent ID: 10693104

Abstract:
An organic EL device (100A) includes an active region (R1) including a plurality of organic EL elements and includes a peripheral region (R2) located in a region other than the active region. The organic EL device includes an element substrate (1) including a substrate, and the plurality of organic EL elements supported by the substrate; and a thin film encapsulation structure (10A) covering the plurality of organic EL elements. The thin film encapsulation structure includes a first inorganic barrier layer (12), an organic barrier layer (14) in contact with a top surface of the first inorganic barrier layer, and a second inorganic barrier layer (16) in contact with the top surface of the first inorganic barrier layer and a top surface of the organic barrier layer. The peripheral region includes a first protruding structure (22a) including a portion extending along at least one side of the active region, the first protruding structure being supported by the substrate, and also includes an extending portion (12e), of the first inorganic barrier layer, extending onto the first protruding structure, the first protruding structure having a height larger than a thickness of the first inorganic barrier layer.
