Abstract
A display device uses an organic actuator as a pixel, and an under-layer substrate is formed underneath the actuator. A surface of the actuator is set to a black and a surface of the substrate is set to a white. Seeing the actuator from an outside, the surface of actuator is visible in a black when the actuator is a planar state and visible in a white when the actuator is inflected, which realizes a display. In addition, the actuator has a memory effect by utilizing a shape memory effect and Coulomb force of the organic material.
