Abstract:
Provided is a method of forming a film having a surface structure of a random wrinkles. A compound according to the present invention is coated and then, a film having a surface structure of random wrinkles may be simply formed through simple ultraviolet (UV) curing or thermosetting. When the film thus formed is used in an organic light emitting device, light generated from the organic light emitting device is scattered on surfaces of the random wrinkles to prevent light guide or total reflection, and thus, light is extracted to the outside. That is, a random structure disposed at the outside of the device performs a light extraction function and consequently, light efficiency of the organic light emitting device may be increased.
