Abstract
An anisotropic conductive film (ACF) is disclosed. The ACF includes a film, an adhesive layer positioned on the film, and one or more conductive balls within the adhesive layer. The conductive balls include a first core part having a first hardness, a second core part covering the first core part and having a second hardness that is greater than the first hardness, and a conductive part covering the second core part, respectively.
