摘要:
A 3-D label is disclosed including moving patterns using fine patterns and microlenses, including a lens layer in which a pattern display unit having microlenses that are convex in a semicircumferential form arranged at specific intervals and to represent patterns formed in a pattern layer regardless of a visual field focal length and a secret unit placed on one side of the pattern display unit and displaying intended patterns formed in the pattern layer when a predetermined visual field focal length is reached are integrated and formed; and the pattern layer disposed under the lens layer and having patterns formed thereon so that the distance between the central point of each of the microlenses and the central point of an adjacent microlens is matched with the distance between the central point of each of pattern cells and the central point of an adjacent pattern cell in the state.
