Abstract:
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.
