  • Patent number: 10141084
    Abstract: An anisotropic conductive film, the anisotropic conductive film including an insulating layer and a conductive layer laminated on the insulating layer, the conductive layer containing conductive particles, wherein after glass substrates are positioned to face each other on the upper and lower surface of the anisotropic conductive film and are pressed against the anisotropic conductive film at 3 MPa (based on the sample area) and 160° C. (based on the detection temperature of the anisotropic conductive film) for 5 sec, a ratio of the area of the insulating layer to that of the conductive layer is from about 1.3:1 to about 3.0:1.
