Abstract
A form of a color-changeable plastic includes: a first conductive electrode layer; a color change layer disposed on the first conductive electrode layer, configured to cover a top surface of the first conductive electrode layer, and made of a substance that changes color depending on whether a voltage is applied; a second conductive electrode layer disposed on the color change laver, configured to cover a top surface and side surfaces of the color change layer, and configured to change the color of the color change layer with the first conductive electrode layer when the voltage is applied; and a conductive guide disposed at at least one of the first conductive electrode layer or the second conductive electrode layer, and configured to guide a movement of electrons and a color change direction of the color change layer when the voltage is applied.
