Abstract
A method for making a support plate for an electrowetting device includes providing the support plate with a hydrophobic layer; arranging a pattern of hydrophilic material on the hydrophobic layer; and removing a surface layer of the hydrophobic layer by a solvent. The electrowetting device may include a support plate with a hydrophobic layer having a thickness, and a pattern of hydrophilic material arranged on a first area of the hydrophobic layer, the thickness of the hydrophobic layer being larger within the first area than outside the first area.
