A method of manufacturing an electrowetting device includes dispensing a first liquid on a surface of a support plate and dispensing a second liquid to adjoin the first liquid. The first liquid is a solution. A first portion of the first liquid transfers into the second liquid to form a first layer of liquid and a second layer of liquid substantially immiscible with the first layer. The first layer comprises a second portion of the first liquid and the second layer comprises the second liquid and the first portion.
