Abstract: Disclosed herein are an anisotropic conductive film including a polymer layer that restricts a movement of conductive particles and a method of manufacturing the same. An anisotropic conductive film (ACF) including a plurality of conductive particles according to an embodiment includes a polymer layer in which the plurality of conductive particles is dispersed and disposed and which restricts a movement of the plurality of conductive particles by capturing the conductive particles and an adhesive layer configured on the upper and lower parts of the polymer layer to assign adhesiveness.

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.
