Abstract
The present invention relates to a method for manufacturing an ultrathin organic light-emitting device and, more specifically, to a method for manufacturing an ultrathin organic light-emitting device capable of dramatically reducing the thickness thereof, in addition to improving light extraction efficiency. To this end, the present invention provides a method for manufacturing an ultrathin organic light-emitting device, comprising: a polymer material coating step for coating a polymer material onto a support; a frit coating step for coating a frit paste onto the polymer material; a heat treatment and separation step for conducting heat treatment at a temperature at which the polymer material breaks down, thereby separating the support and a frit substrate which has been formed by heat-treating the frit paste; and a device layer forming step for forming, in sequence, a device layer comprising a first electrode, a device layer comprising an organic light-emitting layer, and a device layer comprising a second electrode, on one side of the frit substrate which has been in contact with the polymer material.
