Abstract
A method for fabricating an electrowetting display may include disposing an etching barrier on a substrate to delineate a first region and a second region of the substrate, the etching barrier covering the second region of the substrate; etching the first region of the substrate to form an etched first region of the substrate, wherein at least a portion of the second region of the substrate is a protrusion formed in response to the etching of the first region; removing the etching barrier; disposing a black matrix on the second region of the substrate; and forming a spacer over the black matrix disposed on the second region of the substrate.
