A method for manufacturing an organic EL device according to an embodiment of the present invention includes: a step for preparing an element substrate having a substrate and a plurality of organic electroluminescent elements (3) which are supported by the substrate; and a step for forming a thin film encapsulation structure (10) covering the organic electroluminescent elements. The step for forming a thin film encapsulation structure includes: a step A for forming a first inorganic barrier layer (12); after the step A, a step B for detecting particles (P) below or above the first inorganic barrier layer (12) and obtaining positional information on each particle; a step C in which microscopic liquid drops of a coating liquid containing a photocurable resin are applied for each particle by an inkjet, method on the basis of the positional information; after the step C, a step D for irradiating the photocurable resin with an ultraviolet ray and curing the photocurable resin to form an organic barrier layer (14); and after the step D, a step E for forming a second inorganic barrier layer (16) on the first inorganic barrier layer and the organic barrier layer.
