Abstract
Described is a process for manufacturing a light emitting polymer device comprising, in one embodiment, the steps of providing a transparent or non-transparent electrode-containing substrate adapted to act as a first electrode, screen printing a light emitting polymer layer, which is composed of a light emitting polymer dissolved in a solvent, onto the hole injection layer and screen printing a hole injection layer onto the transparent electrode-containing substrate on one side of the light emitting polymer layer.
