Production of organic luminescence device

Abstract

An organic luminescence device is formed from a pair of electrodes, and a layer of organic material disposed between the electrodes so as to cause luminescence in response to a voltage applied between the electrodes. The type of organic luminescence device may be provided with improved luminescence performance if it is produced through a process including a wet-patterning step using an ink of the organic material within a hydrophobic organic solvent having a dissolving power of at most 5 wt. % of water at room temperature for producing the organic material layer.
