ANISOTROPIC CONDUCTIVE FILM, CONNECTION METHOD AND CONJUGANT

摘要

PROBLEM TO BE SOLVED: To provide an anisotropic conductive film or the like which is capable of confirming a satisfactory connection state and a defective connection state from a change of a hue and improves storage stability.SOLUTION: The anisotropic conductive film is configured to conductively connect in an anisotropic manner a terminal of a first circuit member and a terminal of a second circuit member. The anisotropic conductive film comprises a first layer containing a film formation resin and a second layer containing a film formation resin. At least either the first layer or the second layer contains conductive particles. One of the first layer and the second layer contains a leuco dye and the other layer contains a hue change agent which interacts with the leuco dye to change a hue of the anisotropic conductive film.
