Abstract
A method for fabricating an electrowetting display may include depositing a sacrificial layer on a support plate, etching portions of the sacrificial layer to form liquid duct forms on the support plate, depositing a photoresist layer on the liquid duct forms and the support plate, etching portions of the photoresist layer to form a spacer grid, and removing the liquid duct forms to form liquid ducts between the support plate and the portions of the spacer grid.
