Abstract: Disclosed are a self-exposure method for a surface of conductive particles anchored in a polymer layer, a method of fabricating an anisotropic conductive film using the self-exposure method, and the anisotropic conductive film. A self-exposure method for a surface of conductive particles within a polymer layer may include controlling surface energy of multiple conductive particles so that a difference between surface energy of polymer to be used to fabricate the polymer layer and surface energy of the multiple conductive particles to be included in the polymer layer is a preset difference or more, forming a polymer solution by dissolving the polymer into a solvent in which the conductive particles having controlled surface energy have been mixed, and generating the polymer layer from which at least part of a surface of the multiple conductive particles has been externally exposed due to a difference in the surface energy by drying the polymer solution.
