ABSTRACT:
A display device includes a first substrate and a second substrate disposed opposite to each other, and a display medium including an insulating liquid and electrophoretic colored particles dispersed therein and disposed between the first and second substrates. A first electrode and a second electrode are provided for applying a voltage to the display medium so as to move the colored particles between the first and second electrodes to effect a display depending on a voltage applied to the first and second electrodes. The electrophoretic colored particles are distributed uniformly without localization by incorporating the display medium in a plurality of light-transmissive tubes, and disposing and fixing the plurality of tubes in intimate contact with each other between the first and second substrates.
