METHOD OF FABRICATING EXTREMELY SLIM OLED

The present invention relates to a method for fabricating an ultra-thin organic light emitting diode and, more specifically, to a method for fabricating an ultra-thin organic light emitting diode capable of improving outcoupling efficiency and also reducing thickness dramatically. For this, the present invention provides a method for fabricating an ultra-thin organic light emitting diode, including: a polymer material coating step of coating a polymer material on a support; a frit coating step of coating a frit paste on the polymer material; a thermal annealing and separation step of separating the support and a frit substrate made by thermal annealing of the frit paste by thermal annealing at a temperature at which the polymer material is dissolved; and a device layer forming step of forming a device layer including a first electrode, an organic light emitting layer and a second electrode on one side of the frit substrate sequentially, which has contacted the polymer material.
