Abstract
A method of manufacturing an electrowetting display device includes a preliminary partition wall pattern formed on a lower substrate on which a pixel electrode of an oxide series and an insulation layer are formed. The preliminary partition wall pattern is disposed along a boundary of the pixel electrode. A water-repellent layer including a self-assembled monolayer having a hydrophobic property is formed on the lower substrate. A portion of the preliminary partition wall pattern and the water-repellent layer formed on the preliminary partition wall pattern are removed to form a partition wall pattern on the insulation layer and to form a water-repellent pattern on the pixel electrode and the insulation layer between partition walls of the partition wall patterns. A fluid layer is formed on the lower substrate on which the water-repellent pattern is formed. The lower substrate and an upper substrate are combined with each other.
