摘要:
In a method of forming a pattern of an organic light emitting device (OLED), an organic material is evaporated in a predetermined pattern by using a pre-patterned heating element, and the evaporated organic material is transferred to a substrate where the OLED is formed. The method includes preparing a template having a heating element in a pattern corresponding to a multilayered structure of an OLED including a plurality of functional layers; forming an organic layer on the heating element; drawing a substrate for the OLED near to the heating element of the template; and transferring the organic layer on the heating element to the substrate by evaporating the organic layer using the heating element.
