Abstract (en)

[origin: WO02063700A1] The invention relates to an improved method for producing a light-emitting device, comprising the following steps: (i) pre-coating of a substrate with a first, preferably transparent conductive layer or use of a preferably transparent, conductive substrate as the first layer, said first layer exhibiting a high work function and preferably being able to act as an ohmic hole-injection electrode, (ii) direct application of a thin, transparent layer of a preferably soluble monomer or polymer or a mixture of at least one monomer and/or at least one polymer, preferably from a solution, to the first layer and (iii) creation of a preferably negative electron injecting contact, in particular preferably consisting of calcium or a metal with a low work function, by direct application to the polymer film. At least one layer is applied by means of dip coating.
