Abstract

A display device is provided with a wall part forming a space, a contact particle comprising layer having contact particles which are brought into contact with an inner face of the wall part and are charged, a scattering object which is arranged in the space and scatters light or a colored object having a hue different from that of the contact particle and with a pair of electrodes generating an electric field operating on the contact particles when voltage is applied. Voltage is applied between a pair of the electrodes. Thus, the contact particles move along the inner face while they are brought into contact with the inner face of the wall part.
