Anisotropic conductive film

The invention relates to an anisotropic conductive film which comprises a resin film and conductive particles. The resin film is provided with a middle area and a periphery area; conductive particles with first density in the middle area are prevented from gathering by the ionizing-in of the conductive particles; conductive particles with second density are prevented from gathering by the ionizing-out of the conductive particles; and the first density is larger than the second density. The invention overcomes the defects that a large amount of conductive particles gather on two sides of the anisotropic conductive film when the prior ACF is used for splicing TCP to cause two adjacent TCP pins to mutually conduct electricity and cause bright line to be poor, improves the quality of the anisotropic conductive film and particularly improves the quality of the anisotropic conductive film used for a liquid crystal display device.
