Method for fabricating organic EL device

1. A method for fabricating an organic electroluminescence (EL) device having a flexible substrate, the method comprising:

forming an adhesive layer on a part of a surface of the flexible substrate;

forming a magnetic material layer on the surface of the flexible substrate in a part other than the part on which the adhesive layer is formed;

temporarily holding, using magnetic force, the flexible substrate on which the adhesive layer and the magnetic material layer are formed, above an inflexible substrate having magnetic property;

fixing the flexible substrate with the inflexible substrate via the adhesive layer;

forming a layer composing an organic EL unit on the flexible substrate temporarily held using the magnetic force and fixed via the adhesive layer;

removing the part in which the flexible substrate and the inflexible substrate are fixed via the adhesive layer;

separating the flexible substrate on which the layer composing the organic EL unit is formed from the inflexible substrate; and

separating the magnetic material layer from the flexible substrate separated from the inflexible substrate,

wherein fixing the flexible substrate with the inflexible substrate via the adhesive layer is performed at the same time, before, or after temporarily holding the flexible substrate on the inflexible substrate using the magnetic force, and

removing the part in which the flexible substrate and the inflexible substrate are fixed via the adhesive layer is performed at the same time or before separating the flexible substrate from the inflexible substrate.

2. The method for fabricating the organic EL device according to claim 1 ,

wherein the magnetic material layer is formed of a resin containing magnetic particles.
