Encapsulation adhesive film

An encapsulation adhesive film comprising an adhesive film body, wherein the encapsulation adhesive film further comprises:

• a surface pattern provided on at least one surface of the adhesive film body, and the surface pattern comprises:
• a first pattern, extending along a first direction;
• a second pattern, extending along a second direction;
• the first direction intersecting the second direction at a predetermined angle, the predetermined angle being greater than 0° and less than 180°;
• the surface pattern comprises at least one of the first pattern and at least one of the second pattern;
• wherein
• when the predetermined angle is greater than 0° and less than or equal to 90°, the length-to-width ratio of the first pattern is (1.5-100):1, and the length-to-width ratio of the second pattern is (1.5-100):1;
• or
• when the predetermined angle is greater than 90° and less than 180°, the length-to-width ratio of the first pattern is (1.5-10):1, and the length-to-width ratio of the second pattern is (1.5-10):1;
• and
• the first pattern and the second pattern are protrusions.
