Particle moving type display device

A display device comprising:

• a transparent first boundary member having a display side;
• a second boundary member disposed at a predetermined distance from said first boundary member;
• partition walls disposed between said first and second boundary members and forming an enclosed gap therebetween;
• two types of charged particles and a dispersion medium disposed in the gap between said first and second boundary members, said two types of charging particles having different charging polarities and optical characteristics;
• first and second electrodes to which voltages are applied and which move the charged particles in the gap to form a display;
• and
• reflection means for reflecting transmitted light to the display side of said first boundary member.
