Abstract
A substrate for an electrowetting display device including a pixel electrode, a partition wall pattern and a water-repellent pattern. The pixel electrode is formed on a base substrate. The partition wall pattern is disposed along an edge of the pixel electrode to expose the pixel electrode. The water-repellent pattern is disposed at a space formed by the pixel electrode and the partition wall pattern to be extended along a lower portion of side surfaces of the partition wall pattern from an area on which the pixel electrode is formed. The water-repellent pattern exposes an upper portion of the side surfaces and an upper surface of the partition wall pattern. Thus, a manufacturing reliability of a substrate for an electrowetting display device is improved to prevent a display quality from being reduced.
