Abstract
Disclosed herein are an anisotropic conductive film including a polymer layer that restricts a movement of conductive particles and a method of manufacturing the same. An anisotropic conductive film (ACF) including a plurality of conductive particles according to an embodiment includes a polymer layer in which the plurality of conductive particles is dispersed and disposed and which restricts a movement of the plurality of conductive particles by capturing the conductive particles and an adhesive layer configured on the upper and lower parts of the polymer layer to assign adhesiveness.

A method, the method comprising:
- dissolving polymer to form a first polymer solution by mixing the polymer and a solvent at a determined ratio;
- forming a second polymer solution by dispersing a plurality of conductive particles into the first polymer solution;
- fabricating a polymer layer through roll-to-roll coating, by which the second polymer solution passes through a calendar roll along with a release paper;
- removing a first portion of the polymer layer that surrounds a first surface portion of a conductive particle of the plurality of conductive particles and a second portion of the polymer layer that surrounds a second surface portion of the conductive particle, thereby exposing the first surface portion and the second surface portion of the conductive particle from the polymer layer, the first surface portion and the second surface portion of the conductive particle opposite to one another in a first direction;
- and
- coupling an adhesive layer on the polymer layer and covering at least one of the first surface portion or the second surface portion of the conductive particle.
