A display device includes a transparent first boundary member having a display side, a second boundary member disposed at a predetermined distance from the first boundary member, and partition walls disposed between the first and second boundary members and forming an enclosed gap therebetween. Two types of charged particles and a dispersion medium are disposed in the gap between the first and second boundary members, with the two types of changing particles having different charging polarities and optical characteristics. Also included are first and second electrodes to which voltages are applied and which move the charged particles in the gap to form a display, with the first electrode disposed proximate to the first or second boundary members and the second electrode disposed proximate to the portion walls, and a light reflection member on the second boundary member for reflecting light to the first boundary member.
