FIELD: physics.
SUBSTANCE: invention relates to organic light-emitting diode (OLED) solid-state light sources used to make colour information screens and colour display devices with high consumer properties, as well as cheap and efficient light sources. Disclosed is an OLED, having a base in form of a transparent substrate having a transparent anode layer and a metal cathode layer with a light-emitting layer in between, which is based on a dendronised polyaryl silane of general formula (I) 
or (II) 
, where n is an integer from 5 to 1000.
EFFECT: wide range of OLEDs with high operational characteristics, particularly in the radiation range of 400-700 nm, which enables use thereof as light sources.
