ORGANIC ELECTROLUMINESCENT DEVICE Russian patent published in 2011 - IPC H01L51/52 

FIELD: physics.

SUBSTANCE: organic electroluminescent device with a set of layers (1, 2, 3) for emitting light (4) through a partially transparent top electrode (3) has a conducting foil (1). The foil has a base material with top and bottom sides as a substrate and a first metallic layer with such thickness having a surface resistance 0.05 Ohm/m² on the top side of the base material (11). The later has at least a first metallic layer (121) as a bottom electrode and a second metallic region (122) which is electrically insulated from the first metallic region (121) and can provide direct electrical contact with the transparent top electrode (3), a stack (2) of organic layers deposited on the top part of the bottom electrode (11) and designed for emitting light (4), a transparent electrode (3) on the top part of the set (2) of organic layers and at least a partially transparent protective element (5) which covers at least the top electrode and the set (2) of organic layers.

EFFECT: design of large organic light-emitting devices with uniform illumination on the entire light-emitting region.
