The present invention relates to a composition for an anisotropic conductive film, comprising: an epoxy resin containing polycyclic aromatic rings; an acrylic rubber-based resin; conductive particles; and a hardener. After hardening, the epoxy resin containing polycyclic aromatic rings has a glass transition temperature (Tg) of 165°C to 220°C, the acrylic rubber-based resin has a Tg of 0°C to 20°C, and the combined content of the epoxy resin containing polycyclic aromatic rings and the acrylic rubber-based resin is 45 to 65 wt % of the overall weight percentage of the composition (solid portion). The composition for an anisotropic conductive film not only has both flexibility and impact resistance to compensate for the brittle property of epoxy resin under high temperature and high moisture conditions to prevent a hardened anisotropic conductive film from cracking, but can also lower connection resistance and can supplement thermal stability so as to exhibit high reliability and high adhesiveness. |
