1. An anisotropic conductive film comprising:
a first resin insulating layer disposed over a first surface of a conductive layer; and
a second resin insulating layer disposed over a second surface of the conductive layer,
wherein the conductive layer is disposed between the first resin insulating layer and the second resin insulating layer and comprises a base layer, a plurality of conductive particles arranged in the base layer and a nonconductive nano fiber connecting the plurality of conductive particles to each other, the nonconductive nano fiber disposed between adjacent conductive particles being disposed to be space apart from the first resin insulating layer and the second resin insulating layer,
wherein the first resin insulating layer and the second resin insulating layer each comprise a same material and have different thicknesses from each other,
wherein the nonconductive nano fiber comprises a material having a glass transition temperature higher than a glass transition temperature of each of the first resin insulating layer and the second resin insulating layer, and a melting point lower than a melting point of the plurality of conductive particles, and
wherein the nonconductive nano fiber does not overlap in a plan view.
