Abstract: an anisotropic conductive adhesive which uses conductive particles where a silver-based metal is used as a conductive layer, having high light reflectance and excellent migration resistance is provided. The anisotropic conductive adhesive includes light reflective conductive particles in an insulating adhesive resin. The light reflective conductive particle includes a light reflective metal layer made of a metal alloy including silver, gold and hafnium formed on the surface of a resin particle as a core by sputtering method. The light reflective metal layer is preferably formed having a composition ratio of a silver of at least 50% by weight to at most 80% by weight: a gold of at least 10% by weight to at most 45%: a hafnium of at least 10% by weight to at most 40% by weight, and a total ratio does not exceed 100% by weight.

Abstract: An anisotropic conductive adhesive which uses conductive particles where a silver-based metal is used as a conductive layer, having high light reflectance and excellent migration resistance is provided. The anisotropic conductive adhesive includes light reflective conductive particles in an insulating adhesive resin. The light reflective conductive particle includes a light reflective metal layer made of a metal having at least 60% of reflectance at a peak wavelength of 460 nm formed on the surface of a resin particle as a core, and a coating layer made of a silver alloy formed on the surface of the light reflective metal layer. The light reflective metal layer is preferably formed by a plating method.
