Abstract
A method for manufacturing an electrowetting device provides a first fluid on a surface of a substrate. The method includes the steps of immersing part of the substrate in a second fluid, the second fluid being immiscible with the first fluid, and a surface of the second fluid forming a gutter along the surface of the substrate; providing a quantity of the first fluid in the gutter; and moving the gutter along the surface of the substrate, the surface of the substrate and a horizontal plane forming an angle between 100 degrees and 170 degrees. Also disclosed is an apparatus for performing the method.
