Abstract
Example embodiments relate to a reflective type display apparatus using dielectrophoresis and a method of manufacturing the reflective type display apparatus. The display apparatus may include a first substrate and a second substrate arranged so as to face each other; a hydrophobic insulating layer formed on the first substrate; a hydrophobic pattern electrode unit arranged to form a non-uniform electric field; a hydrophilic dielectric medium with hydrophobic uncharged particles therein in a space between the first substrate and the second substrate; and a reflective plate arranged under the first substrate. The display apparatus may form an image by using dielectrophoresis of the hydrophobic uncharged particles according to an electric field gradient formed by the hydrophobic pattern electrode unit.
