Display device using electrowetting

A display device including a plurality of pixels, each comprising:

• a first substrate and a second substrate arranged a distance apart from each other;
• a reservoir layer on the first substrate and including a reservoir;
• a first electrode and a second electrode on an upper surface of the reservoir layer and on an inner wall of the reservoir, respectively;
• a plurality of first dielectric layers and a plurality of second dielectric layers alternately formed on the upper surface of the reservoir layer to cover the first electrode, the plurality of first and second dielectric layers having hydrophobic surfaces and hydrophilic surfaces, respectively;
• a third dielectric layer on the inner wall of the reservoir to cover the second electrode, the third dielectric layer having a hydrophobic surface;
• a third electrode on a lower surface of the second substrate;
• a plurality of fourth dielectric layers and a plurality of fifth dielectric layers alternately formed on a lower surface of the second substrate to cover the third electrode, the plurality of fourth and fifth dielectric layers having hydrophobic surfaces and hydrophilic surfaces, respectively;
• and
• a transparent oil and a water-soluble liquid having a color filling a space between the first, second, and third dielectric layers and the fourth and fifth dielectric layers.
