Claim of US Patent No. 10,602,619

1. An anisotropic conductive connection structure body comprising:a first electrode terminal on a surface of which a protruding portion is formed;
a second electrode terminal; and
an anisotropic conductive adhesive layer containing electrically conductive particles that provide conduction between the first electrode terminal and the second electrode terminal,
wherein a ratio of a height of the protruding portion to a before-compression particle size of the electrically conductive particles is less than 60%,
an opening area ratio of the first electrode terminal is more than or equal to 55%, and
a height of the second electrode terminal is more than or equal to 6 ?m.
