Abstract
A picture display device includes display elements reflecting specific wavelengths of visible light; and shape deformation portions for inducing elastic deformation of the display elements. The individual display elements have colloidal particles arrayed at regular spacing, and an elastically deformable filler material intervening between the colloidal particles. The shape deformation portion includes a shape retention component formed of a material capable of reversible plastic deformation by external force.
