Electroluminescent device and method for manufacturing thereof

摘要

An electroluminescent device has at least two electroluminescent elements arranged on a substrate in accordance with a desired pattern, each element comprising a first and a second electrode layer and, disposed therebetween, an electroluminescent layer obtained from a liquid layer. A partitioning relief pattern including partitioning ribs of an insulating material protruding from the substrate, forms enclosure areas for containing the liquid layer in accordance with the desired pattern. In order to prevent mixing of liquids between adjacent electroluminescent elements and to allow filling of a maximum amount of liquid in each element, the partitioning element between adjacent elements is comprised of at least two partitioning ribs with an intermediate groove in the area between the partitioning ribs. The invention also refers to a method for manufacturing of an electroluminescent device.
