Abstract: A method of manufacturing an organic EL display includes forming organic EL elements on a first portion of a first substrate, forming a frame-shaped sealing resin layer on the first portion such that the sealing resin layer surrounds the organic EL elements, putting the first substrate and a second substrate together such that the sealing resin layer is interposed between the first and second substrates, thereby forming a prebroken panel, and breaking the first substrate of the prebroken panel along a boundary between the first portion and a second portion of the first substrate, wherein, before forming the sealing resin layer, a release layer is formed on the second portion at a position adjacent to the boundary, the release layer including a layer made of a material equal to a material of a layer included in an organic layer of the organic EL element.
