An optical clear adhesive film is provided. A first tearing part is disposed on a first side of a first protective film, such that when an external force is applied to the first tearing part, a starting position at which the colloid layer is separated from the first protective film is a line contact. Therefore, the colloidal layer is less stressed at each point of separation, and phenomenon that the colloid layer is pulled is avoided.
