Abstract:
1. 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 first dielectric layer, having a plurality of dielectric layers, on the reservoir layer to cover the first and second electrodes, the plurality of dielectric layers in the first dielectric layer include hydrophobic surfaces and hydrophilic surfaces in an alternate manner; a third electrode on a lower surface of the second substrate; a second dielectric layer, having a plurality of dielectric layers, on the lower surface of the second substrate to cover the third electrode, the plurality of dielectric layers in the second dielectric layer include hydrophobic surfaces and hydrophilic surfaces in an alternate manner; 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 transparent water-soluble liquid and an oil having a color filling a space between the first dielectric layer and the second dielectric layer; and an optical pattern between the first electrode and the reservoir layer, the optical pattern diffusing light on the upper surface of the reservoir layer.
