Abstract

The present invention discloses an anisotropic conductive adhesive comprising an insulating adhesive component and a number of conductive particles dispersed in the insulating adhesive component, wherein the insulating adhesive component contains a crosslinked rubber resin. The anisotropic conductive adhesive of the present invention prevents exfoliation of an adhesive or reduction in adhesive strength of circuit by minimizing its the heat-contraction occurring in the process of a polymerization or a hardening reaction when connecting micro-circuits, whereby a short circuit between adjacent electrodes can be prevented when connecting the circuits, and excellent connection reliability according to a long-term use is achieved.
