The present invention provides a compound capable of forming an irregular wrinkled structure, a composition containing the compound, a film having the irregular wrinkled structure, a method of forming the film, and an organic light emitting diode comprising the film. The film can be formed with the irregular wrinkled structure by simply coating the compound of the present invention, and curing using UV rays or heat. By applying the formed film to the organic light emitting diode, light emitted from the organic light emitting diode is scattered on the surface of irregular wrinkles and is extracted to the outside after controlling the optical wave or total reflection. A random structure located on the outside of the diode functions as a light extraction unit for improving the light efficiency of the organic light emitting diode.
