The present inventive concept relates to an electrowetting display device including a lyophobic colloid material and a polymer resin such as an organic layer or a polyimide (PI), and a lyophobic layer including a supporting layer supporting the lyophobic colloid material and using a photoreactive fluorine-based surfactant for a fluorine-based material to be positioned above and for a hardened photoreactive material layer to be positioned below through exposure in a single step without separately performing a hydrophilic treatment and then a water-repellent treatment, thereby reducing the number of processes, the manufacturing time, and the cost.
