Abstract
Disclosed are a conductive particle, an anisotropic conductive film, a display device, and a method for fabricating the same so as to detect the extent to which the conductive particles are cracked in a heating and pressurizing process, to thereby improve the ratio of finished products while the display device is being manufactured. A core of the conductive particle is a fluorescent resin core. In the conductive particle according to this disclosure, the core of the conductive particle is a fluorescent resin core, and the extent to which the conductive particle is cracked can be detected by detecting varying fluorescence in a heating and pressuring process, to thereby alleviate such a phenomenon from taking place that the conductive particle has a poor electrical conductivity due to an insufficient pressure, or the conductive particle is cracked, and thus loses its electrical conductivity, due to an excessive pressure.
