Abstract: A display panel includes a first substrate and a second substrate which are arranged opposed to each other. The space between the first substrate and the second substrate is separated into a plurality of sub-pixel regions. Within each sub pixel region, a first electrode, a first fluid layer, a second fluid layer, a hydrophobic dielectric layer and a second electrode are arranged in this order. The first fluid layer is made of hydrophilic liquid. The second fluid layer is made of ink. When no electric field is applied between the first electrode and the second electrode, the ink spreads over the surface of the hydrophobic dielectric layer. When an electric field is applied between the first electrode and the second electrode, the ink aggregates to expose the hydrophobic dielectric layer.
