A method for manufacturing an organic light emitting display. Pixel portions are formed on a mother substrate. A test wiring for testing pixel portions is formed at a peripheral portion of the mother substrate. A sealing material is formed at one surface of a sealing substrate to enclose the pixel portions, the sealing substrate being sealed to be spaced apart from the mother substrate. A spacer is formed at a side region of the one surface of the sealing substrate on which the sealing material is formed. The mother substrate and the sealing substrate are adhered to each other by the sealing material to seal the pixel portions within an enclosure formed by the mother substrate, sealing surface, and sealing material. A part of the sealing substrate is scribed and removed to expose the test wiring, the part of sealing substrate being arranged over a portion of the test wiring.

Manufacture and method of sealing an organic light emitting display

An organic electroluminescent (EL) display device includes an organic EL element formed on a substrate. The organic EL element includes a lower electrode, an organic EL layer and an upper electrode that are sequentially stacked on the substrate. A flat panel is attached to the substrate to encapsulate the organic EL element. At least one through hole is formed in the organic EL display device so as to allow gas inside the organic EL display device to flow out during an encapsulation process. A cap is provided to shut the one or more through holes.

Method of encapsulating organic EL display device having through hole in substrate and/or flat panel

A method of manufacturing an organic electroluminescent display device includes preparing an auxiliary substrate, which has a flat side; forming a first protective layer on the auxiliary substrate; forming an organic electroluminescent unit on the first protective layer; bonding a flexible main substrate onto the organic electroluminescent unit; and etching the auxiliary substrate to remove the same.

Method of manufacturing substrate, method of manufacturing organic electroluminescent display device using the method, and organic electroluminescent display device

An electroluminescent (EL) device having a substrate with a light-emitting portion and a sealing member. The sealing member seals the light-emitting portion from the surrounding air. A groove accommodating a sealant is formed in at least one of seal portions of the substrate and the sealing member.
