摘要: An electroluminescent device includes a substrate and a laminated body composed of a first electrode, an electroluminescent layer and a second electrode. The light output out of the electroluminescent device is increased by arranging a colloidal layer between the substrate and the laminated body. By using pigments in the colloidal layer, the emission color of the electroluminescent device can be changed and the daylight contrast improved.

摘要: The invention describes a light-emitting device which comprises at least a substrate (1), an anode (2), a first hole transport layer (3), a light-emitting layer (5) and a cathode (6), and in which a first hole blocking layer (4) is arranged between the first hole transport layer (3) and the light-emitting layer (5). The hole blocking layer (4) reduces the concentration of holes which reach the light-emitting layer (5) and thus the concentration of holes, which are usually the majority charge carriers, can be adapted to the electron current.
