ABSTRACT:
Disclosed is an electrophoretic display device and a method for manufacturing the same, which facilitate high reflectivity, high contrast ratio and easy removal of line-shaped spots occurring when a release film is removed from an electrophoretic film. The electrophoretic display device comprising a substrate; a gate line, a data line, a storage electrode and a switching element on the substrate; a first passivation film on the gate line, data line, storage electrode, switching element and substrate, the first passivation film including first and second regions, the first region corresponding to the gate line, data line and switching element, the second region being a region other than the first region; a plurality of first dielectric patterns on the second region, the plurality of first dielectric patterns being apart from one another; a pixel electrode on the plurality of first dielectric patterns; and an electrophoretic film on the pixel electrode.
