Abstract:
1. A method for manufacturing a light emitting device comprising a pixel portion with a plurality of light emitting elements, wherein each of the plurality of light emitting elements includes a cathode, a layer containing an organic compound, and an anode between a pair of light-transmitting substrates, the method comprising the steps of: forming the pixel portion of a light emitting element over one substrate of the pair of substrates; forming a columnar spacer over the other substrate of the pair of substrates; forming a sealing material adjacent to the columnar spacer over the other substrate of the pair of substrates; attaching the pair of substrates with the columnar spacer and the sealing material interposed between the substrates and the sealing material disposed around the pixel portion of the light emitting element, with the attaching occurring in a chamber under reduced pressure with a vacuum applied to the chamber set to be 1 Pa or less such that the reduced pressure in the chamber is between 1 Pa and atmospheric pressure; and gradually increasing pressure within the chamber up to atmospheric pressure after the attaching step.
