전기 전도성 접착 필름은 접착제 층 - 접착제 층은 접착제 층의 두께 방향으로 거리 T만큼 이격된 서로 반대편에 있는 제1 주 표면 및 제2 주 표면을 갖고, 여기서 T ≥ 20 마이크로미터임 -, 및 제1 주 표면과 제2 주 표면 사이에서 접착제 층 내에 분산된 복수의 전기 전도성 입자를 포함한다. 복수의 전기 전도성 입자 중 전기 전도성 입자의 90% 이상에 대해, 전기 전도성 입자는 T/4 초과의 입자 직경 D50을 갖고 전기 전도성 입자의 최대 크기는 T 미만이다. An electrically conductive adhesive film includes an adhesive layer having opposing first and second major surfaces spaced apart a distance T in a thickness direction of the adhesive layer, where T≥20 microns, and a plurality of electrically conductive particles dispersed in the adhesive layer between the first and second major surfaces. For at least 90% of the electrically conductive particles in the plurality of electrically conductive particles, the electrically conductive particles have a particle diameter D50 greater thank T/4 and a maximum size of the electrically conductive particles is less than T.
