FIELD: electricity.
SUBSTANCE: invention deals with devices based on organic light diodes. The concept of the invention is as follows: a device on organic light diodes comprises a substrate, the first electrode, arranged above the head, an organic layer arranged above the specified first electrode, including the first area comprising an organic radiating material, and the second area comprising a transparent material, the refraction ratio of which is less than the coefficient of substrate refraction, at the same time the specified second area adjoins the specified first area in the direction parallel to the specified first electrode, and the second electrode located above the specified organic layer.
EFFECT: invention provides for increasing efficiency of light release in devices based on organic light diodes.
