Abstract:
1. An apparatus, comprising: a first member including a plurality of first electrodes on a first substrate; a second member including a plurality of second electrodes on a second substrate, the second electrodes facing the first electrodes of the first member; and an anisotropic conductive film (ACF) disposed between the first member and the second member, the ACF having a double-layered structure and electrically connecting the first member and the second member, the double-layered structure including a first conductive layer and a second non-conductive layer, wherein: a minimum melt viscosity of the first conductive layer is higher than a minimum melt viscosity of the second non-conductive layer, the minimum melt viscosity of the first conductive layer is 10,000 Pa·s to 100,000 Pa·s at about 30° C. to about 200° C., and the ACF includes an epoxy resin with a polycyclic aromatic ring, a phenoxy resin, conductive particles, a curing agent, and inorganic fillers, wherein the epoxy resin with the polycyclic aromatic ring is in an amount of about 30 wt % to about 60 wt % based on total weight of the ACF, and exhibits a combined minimum melt viscosity of the first and second layers of the ACF of about 3,000 Pa·s to about 10,000 Pa·s at about 30° C. to about 200° C.
