Claim:
1. A method for fabricating an electrowetting display, the method comprising: depositing a photoresist layer on a glass substrate; patterning the photoresist layer to produce a patterned photoresist layer that exposes a first region of the glass substrate and covers a second region of the glass substrate; etching the first region of the glass substrate to form an etched first region of the glass substrate, wherein at least a portion of the second region of the glass substrate is a glass protrusion formed in response to the etching of the first region; removing the patterned photoresist layer; placing an opaque black matrix on the second region of the glass substrate; forming a transparent conductive layer on at least a portion of the black matrix and the etched first region of the glass substrate; and forming a spacer on the transparent conductive layer on the second region of the glass substrate.
