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.

Electrowetting display device and manufacturing method thereof

A method of manufacturing an electrowetting display device includes forming a protection layer on a pixel electrode, forming a water-repellent layer on the protection layer, and removing the water-repellent layer from regions surrounding a display area of the pixel electrode. The water-repellent layer is formed by coating the protection layer with a hydrophilic material using a method such as slit coating. The water-repellent layer is removed using a method such as an edge bead removal method. The resulting water-repellent layer has a uniform thickness.

An imprinting apparatus and a method of the same which form a residual film including a uniform thickness all over a substrate. The imprinting apparatus includes a substrate support which supports a substrate which is coated with an imprint resin on an upper surface thereof, an imprint mold arranged on an upper side of the substrate support and which forms a predetermined pattern by molding the imprint resin coated on the substrate, a pressure roller which pressurizes the imprint mold to adhere closely to the substrate, a pressure roller control unit which controls the pressure roller to change a moving velocity and an applied pressure of the pressure roller according to a position of the imprint mold, and a resin curing unit which cures the imprint resin on the substrate.
