Prebroken panel, display, and method of manufacturing the same

A method of manufacturing an organic EL display, comprising:

• forming organic EL elements on a first portion of a first substrate which comprises the first portion and a second portion, wherein each of the organic EL elements comprises a pair of electrodes and an organic layer interposed between the electrodes and including an emission layer;
• forming a frame-shaped sealing resin layer and a dummy sealing resin layer on the first and second portions, respectively, such that the frame-shaped sealing resin layer surrounds the organic EL elements and is spaced apart from the dummy sealing resin layer;
• putting the first substrate and a second substrate together such that the first portion faces a third portion of the second substrate with the frame-shaped sealing resin layer interposed therebetween and the second portion faces a fourth portion of the second substrate with the dummy sealing resin layer interposed therebetween, thereby forming a prebroken panel to be broken into at least one display panel;
• breaking the first substrate of the prebroken panel along a first boundary between the first and second portions;
• and
• breaking the second substrate of the prebroken panel along a second boundary between the third and fourth portions,
• wherein, before forming the frame-shaped sealing resin layer, a first release layer is formed on the second portion at a position adjacent to the first boundary, the first release layer comprising a layer made of a material equal to a material of a layer included in the organic layer, and
• wherein, before forming the dummy sealing resin layer, a second release layer is formed on the second portion at a position where the dummy sealing resin layer is to be formed, the second release layer comprising a layer made of a material equal to a material of a layer included in the organic layer.
