Claim:
1. An electronic device, comprising: an anisotropic conductive adhesive film as a connection material, wherein: the anisotropic conductive adhesive film is formed from a composition that includes: about 10 to about 40% by weight of an ethylene-vinyl acetate copolymer, about 5 to about 40% by weight of a total amount of at least one resin selected from the group of an acrylate modified urethane resin and an ester type urethane resin, about 5 to about 30% by weight of an isocyanurate acrylate, about 5 to about 30% by weight of a dicyclopentadiene (meth)acrylate, and about 5 to about 40% by weight of a film-forming resin, based on the total solid weight of the anisotropic conductive adhesive composition, and the anisotropic conductive adhesive film has a flowability of 50% or more after preliminary pressing at 80° C. and 1 MPa for 1 second and final pressing at 180° C. and 3 MPa for 5 seconds, and a connection resistance increment greater than 0% but not greater than 25%, as calculated by Expression 1: where A is a connection resistance measured after preliminary pressing at 80° C. and 1 MPa for 1 second and final pressing at 180° C. and 3 MPa for 5 seconds, and B is a connection resistance measured after reliability evaluation at a temperature of 85° C. and a humidity of 85% for 250 hours following preliminary pressing and final pressing.
