Abstract
The present invention provides an organic EL display panel manufacturing method which is capable of forming a desired organic film or the like with high accuracy without imparting damages to a substrate and an organic film and an organic EL display panel which is manufactured by the method. An opening portion which corresponds to a panel pattern region of a display panel is formed in a vapor deposition mask. The opening portion has a bottom surface in the inside of a recessed surface which is retracted from a surface on which the vapor deposition mask is brought into contact with the substrate. The opening portion of the vapor deposition mask is spaced apart from the substrate with a predetermined gap space and evaporated particles from an evaporating source are vapor-deposited to the substrate through the opening portion.
