Abstract:
1. A method of manufacturing a substrate for an electrowetting display device, the method comprising: forming a preliminary partition wall pattern on a base substrate on which a pixel electrode is formed; forming a water-repellent layer on the base substrate having the preliminary partition wall pattern, wherein the water-repellent layer covers the preliminary partition wall pattern; forming a mask pattern on the base substrate, the mask pattern exposing an upper surface of the preliminary partition wall pattern and an upper portion of side surfaces of the preliminary partition wall pattern connected to the upper surface; forming a water-repellent pattern by removing the water-repellent layer covering an upper portion of the preliminary partition wall pattern; forming a partition wall pattern, which is lower than a height of the preliminary partition wall pattern, by removing the upper portion of the preliminary partition wall exposed by the mask pattern and the water-repellent pattern; and removing the mask pattern from the base substrate on which the water-repellent pattern and the partition wall pattern are formed.
