  • Patent number: 8211492
    Abstract: The present invention is a fabrication method of a light-emitting device characterized by ejecting a solution containing a luminescent material toward an anode or a cathode under a reduced pressure and characterized in that in a duration before the solution is arrived at the anode or the cathode, the solvent in the solution is volatilized, the remaining part of the luminescent material is deposited on the anode or the cathode, and thereby formed a light-emitting layer. By the present invention, a baking process for thickness reduction is not required after applying the solution. Accordingly, it is possible to provide a fabrication method with high throughput although the method is low in cost and simple.
