Abstract
The present disclosure relates to an electrowetting display device and a manufacturing method for the same, using a UV light reactive fluorosurfactant layer. The UV light reactive fluorosurfactant layer can include a UV-cured fluorine based material positioned above a cured UV reactive material. In an embodiment, the electrowetting display device can also include a substrate with a layer of pixel electrodes formed over the substrate, and partition walls formed over at least a portion of the layer of pixel electrodes. In one embodiment, the UV light reactive fluorosurfactant layer can be formed between the partition walls and above an inter-layer insulation film. In another embodiment, the UV light reactive fluorosurfactant layer can be formed between the partition walls and above the layer of pixel electrodes. The electrowetting display can also include a water repellent layer formed over the UV light reactive fluorosurfactant layer.
