Abstract
Electro-wetting display (EWD) that displays information by controling movement of fluid is one of the strong candidates for electronic paper display (EPD). In EWD cell. the movement of oil which locates between hydrophobic insulation layer and deionized water is rather random, which makes it difficult to realize gray scale, fast response time, and good color characteristics. In this paper, we investigated how to control the oil movement in specific one direction by surface treatment and pattered electrodes. From these experiments, we could control oil movement in a desired direction.
