Patent ID: 8916406

Claim:
A method of producing an organic electroluminescence device comprising at least a layer, and the layer being formed by a wet process comprising the steps of: coating a solution of an organic material dissolved in a solvent to form a liquid layer having a thickness of 1 μm to 100 μm, the solvent having a relative drying rate compared to butylacetate of 1 to 1000 (based on a dry rate of butylacetate being 100) and the organic material being a low molecular weight compound having a molecular weight of 300 to 1600; and then removing the solvent by blowing air onto the liquid layer at an air-blowing rate from 0.1 m/s to 5 m/s and a time between completion of coating and initiation of blowing is from 0 sec. to 60 sec, to form the layer and the layer is a light-emitting layer.
