Electrowetting array substrate and display device
The disclosure of the present invention relates to an electrowetting array substrate and a display device. The electrowetting array substrate comprises a plurality of pixel units. Each pixel unit comprises a common electrode layer, a pixel electrode layer, a hydrophobic dielectric layer provided between the two electrode layers, a non-polar liquid layer spreading on the hydrophobic dielectric layer, and an aqueous electrolyte layer provided between the non-polar liquid layer and the common electrode layer. a surface of the hydrophobic dielectric layer, on which the non-polar liquid layer spreads, is provided with a groove, and the pixel electrode layer is provided with a through hole the position of which corresponds to that of the groove. With such structure, the spread-contract path of the non-polar liquid can be shortened and thus the response rate can be improved. Furthermore, the non-polar liquid can be confined within the pixel unit.
