Document Type and Number:
WIPO Patent Application WO/2019/186806
Kind Code:
A1
Abstract:
This organic EL display device is equipped with a substrate that has a surface upon which a drive circuit containing a thin film transistor is formed, a planarization film that makes the surface of the substrate planar by covering the drive circuit, and an organic light-emitting element that is formed upon the surface of the planarization film and is electrically connected to the drive circuit. The planarization film includes a first inorganic insulating film layered upon the drive circuit, an organic insulating film layered upon the first inorganic insulating film, and a second inorganic insulating film layered upon the organic insulating film. The surface of the second inorganic insulating film that faces the opposite direction from the organic insulating film has an arithmetic mean roughness of no more than 50 nm.
