Anisotropic conductive films, each including an insulating adhesive layer and conductive particles insulating adhesive layer in a lattice-like manner. Among center distances between an arbitrary conductive particle and conductive particles adjacent to the conductive particle, the shortest distance to the conductive particle is a first center distance; the next shortest distance is a second center distance. These center distances are 1.5 to 5 times the conductive particles' diameter. The arbitrary conductive particle, conductive particle spaced apart from the conductive particle by the first center distance, conductive particle spaced apart from the conductive particle by first center distance or second center distance form an acute triangle. Regarding this acute triangle, an acute angle formed between a straight line orthogonal to a first array direction passing through the conductive particles and second array direction passing through conductive particles being 18 to 35°. These anisotropic conductive films have stable connection reliability in COG connection. |

1. An anisotropic conductive film comprising an insulating adhesive layer and conductive particles arranged in the insulating adhesive layer in a lattice-like manner, wherein
when among center distances between an arbitrary conductive particle and conductive particles adjacent to the conductive particle, a shortest distance to the arbitrary conductive particle is defined as a first center distance, and a next shortest distance is defined as a second center distance, the first center distance and the second center distance are each 1.5 to 5 times a particle diameter of the conductive particles, and regarding an acute triangle formed by an arbitrary conductive particle P0, a conductive particle P1 spaced apart from the arbitrary conductive particle P0 by the first center distance, and a conductive particle P2 spaced apart from the arbitrary conductive particle P0 by the first center distance or the second center distance, an acute angle α formed between a straight line orthogonal to a direction (hereinafter, referred to as a first array direction) of a straight line passing through the conductive particles P0 and P1 and a direction (hereinafter, referred to as a second array direction) of a straight line passing through the conductive particles P1 and P2 is 18 to 35°. |
