FIELD: physics.
SUBSTANCE: organic light-emitting diode includes a supporting base in the form of a transparent substrate, inside of which are sealed a transparent anode, a light-reflecting cathode and a set of layers of organic substances in between, said set consisting of at least a transparent hole transfer layer, an emission layer containing organic substances for emitting red (R), green (G) and blue (B) colours, an electron transfer layer; the anode, cathode and layers of organic substances are in the form of hollow cylinders, coaxially inserted into each other.
EFFECT: broader information and functional capabilities of the organic light-emitting diode, high efficiency thereof.
