    Abstract: The invention relates to an electroluminescent device, which comprises a first set of bands and a second set of bands, which are arranged in such a way, that they form a two-dimensional mesh with points of intersection between the bands of the first set and the bands of the second set. The bands in each case consist of a sequence of layers and at least one set of bands contains a light-emitting substance, which emits light when a voltage is applied. The band structure increases the contact areas between the individual bands and the light is generated more efficiently.

    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.
