A distribution density of supports and the spacing therebetween are adjusted to improve a restorability of a light-reflection electrode of a color-changeable pixel. When the spacing between the supports is decreased or the distribution density thereof is increased, a tension per unit area of the light-reflection electrode is raised. If an external force is applied to the light-reflection electrode, the tension caused by the supports will counteract the force and allow the light-reflection electrode to successfully return to the original state after the external force is removed.
