The invention relates to an optically variable element. The optically variable element according to the present invention comprises: at least one protrusion; and a substrate part connected to the lower end of the protrusion part, the substrate part being provided with a reaction part that selectively reacts or adsorbs with a part of the protrusion part, and the angle or shape of the protrusion part being changed on the basis of externally applied energy, thereby changing the light characteristics at a specific angle. 本发明涉及一种光学可变元件。根据本发明的光学可变元件，其包括至少一个突起部；以及连接于突起部下端的基材部，基材部上布置有选择性地与突起部的局部进行反应或者吸附的反应部，基于外部施加的能量改变突起部的角度或者形态，从而使光特性在特定角度发生变化。
