A sign tag comprises a transparent main member having convex members at a side thereof and a pattern at the opposite side thereof and there is a phase deviation between the pattern and the convex members. A base layer is further provided on the second side of the main member sheltering the pattern. The pattern has compressed elements and the convex members serve as convex lens to refract lights reflected from the relative compressed elements of the pattern to form viewing results to a viewer. The positions of the viewing results are changed according to the viewing angle of the viewer such that the viewer will get a dynamically visual effect on the sign tag when he/she changes the viewing angles continuously relative to the sign tag. The method of manufacturing the sign tag comprises the step of preparing the transparent main member and then providing the convex members, the pattern and the base layer on the first and the second sides of the main member respectively.
