Electronic paper display device

An electronic paper display device, comprising:

• a first substrate;
• a second substrate;
• a plurality of display units disposed above the first substrate and below the second substrate, defined by a plurality of partition elements disposed on the first substrate and positioned between the first substrate and a second substrate, forming a plurality of accommodating rooms for the corresponding plurality of display units, wherein each display unit includes an air medium and a plurality of liquid powders distributed in the air medium;
• a plurality of groups of side electrodes disposed on the first substrate, each group of side electrodes comprising a first electrode and a second electrode, wherein each group of side electrodes is disposed in each accommodating room and not in contact with the plurality of partition elements;
• and
• a plurality of light-emitting units, each light-emitting unit disposed between the first electrode and the second electrode of the corresponding group of side electrodes, positioned between the display units and the first base;
• wherein, the light-emitting units are configured for absorbing light energy from an external light source supplying light through the second substrate, and emitting light directed away from the first substrate and through the second substrate for displaying images.
