An electronic device which connects a circuit film to a display panel by applying a conductive material to the insides of holes formed in the circuit film, so as to improve reliability of bonding, and a display device using the same, are discussed.

An electronic device which connects a circuit film to a display panel by applying a conductive material to the insides of holes formed in the circuit film, so as to improve reliability of bonding, and a display device using the same, are discussed.

An electronic device can include a plurality of pad electrodes provided at at least one side of a substrate, at least one circuit film configured to have a plurality of connection electrodes provided at an insulating film to correspond to the plurality of pad electrodes, a plurality of solders to conductively connect the plurality of connection electrodes to the plurality of pad electrodes exposed from the circuit film one-to-one, and an insulating adhesive to fill spaces between the plurality of pad electrodes and the plurality of connection electrodes. Also, each of the plurality of solders has an edge horizontally protruding from the insulating film.
