Abstract:
An anisotropic conductive adhesive film, comprising a first insulating adhesive layer, a second insulating adhesive layer whose modulus of elasticity after being cured is less than the modulus of elasticity of the cured first insulating adhesive layer, and electrically conductive particles which are dispersed in at least either the first insulating adhesive layer or the second insulating adhesive layer, wherein the ratio c1/c2 between the modulus of elasticity c1 of the cured first insulating adhesive layer and the modulus of elasticity c2 of the cured second insulating adhesive layer is at least 10, and an insulating resin used in the first insulating adhesive layer is different from an insulating resin used in the second insulating adhesive layer.
