Abstract: A security label includes a substrate; and a film formed on the substrate and comprising at least one anti-counterfeiting pattern each including a plurality of parallel anti-counterfeiting lines each having a plurality of anti-counterfeiting units. It is easy for consumers to identify the genuine products by viewing the security label placed on the product in a predetermined angle range. The film may be formed on the substrate which may be made of one of a wide variety of materials. No ink, dye, and organic solution are employed in the manufacturing process. The manufacturing cost is decreased greatly. More than one anti-counterfeiting pattern may be formed on the substrate without causing interference. Hence, its anti-counterfeiting effects are excellent. Counterfeiting of the security label is very difficult.
