Abstract

The invention relates to an electroluminescent device comprising a substrate (1), a porous layer (2) that borders on the substrate (1), a laminated body that borders on the porous layer (2) and that is composed of at least a first electrode (3), an electroluminescent layer (4) and a second electrode (5), a colored material, preferably an ink, being present at least partially in the pores of the porous layer (2). The porous layer (2) may be segmented and include a plurality of different colored materials, so that a black matrix structure and/or a color filter structure is obtained. The invention also relates to a method of manufacturing an electroluminescent device.
