Abstract: A slot die coater planarizing an upper surface of an encapsulation layer and a coating method using the same. The slot die coater includes a slit nozzle configured to supply a coating solution. The slit nozzle includes a hole vertically penetrating a center portion thereof, a first bottom surface disposed at a movement direction side of the slit nozzle with reference to the hole, and a second bottom surface disposed at an opposite direction side of the movement direction of the slit nozzle with reference to the hole. A width of the first bottom surface is different from the width of the second bottom surface.

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.
