FIELD: physics.
SUBSTANCE: thin film-like substrate according to the present invention consists of a base and a thin film formed on the base. The base having a thin film also has a first separator which forms a depression on the base, and a second separator formed on the first separator. In the separation region surrounded by the second separator there is a plurality of depressions and the thin film lies in each of the depressions. The organic electroluminescent display device has a thin film-like substrate, as well as a first electrode and a second electrode with a thin film in between, the thin film being an organic electroluminescent layer.
EFFECT: formation of a thin film-like substrate with improved flatness of the thin film and making a display device with fewer display irregularities.
