Abstract
An electrowetting pixel structure includes a substrate, a hydrophobic dielectric layer, a non-polar liquid, a polar liquid, at least one electrode, and at least one contact hole. The hydrophobic dielectric layer is formed on the substrate, the non-polar liquid covers one surface of the hydrophobic dielectric layer, and the polar liquid is provided on the hydrophobic dielectric layer where the non-polar liquid and the polar liquid are immiscible. The electrode is formed on the substrate and divides the substrate into an electrode section and a non-electrode section. When a voltage is applied to the electrowetting pixel structure, the non-polar liquid contracts on the hydrophobic dielectric layer and is confined to an area substantially overlapping the non-electrode section. The contact hole is formed on the substrate at a position away from the non-electrode section of the electrowetting pixel structure.
