Abstract
A method for forming a uniform cavity between electrode substrates of a dlay comprises the steps of patterning a border to define a display area between the electrode substrates, patterning electrode spacers between the electrode substrates, and wafer bonding the electrode substrates to the border and to the electrode spacers to form a uniform cavity within the display area. A cavity comprises a pair of substrates enclosing the cavity and patterned spacers wafer bonded to the substrates to form and maintain a uniform thickness of the cavity.
