Abstract:
1. An electrophoretic display device, comprising: a first substrate and a second substrate having a plurality of pixels, wherein the first substrate includes a display region and a non-display region outside the display region; a switching device on the first substrate, wherein the switching device includes a gate electrode, a source electrode and a drain electrode; an insulating layer on the first substrate; a passivation layer on the entire first substrate including the source electrode and the drain electrode; partition walls formed in direct contact with the passivation layer between each of the pixels of the first substrate, wherein the partition walls are formed along a boundary region of the pixels arranged on the first substrate; a pixel electrode on the passivation layer in the display region of the first substrate and on lateral side walls of the partition walls, wherein the pixel electrode directly contacts the drain electrode via a contact hole in the insulating layer; an electrophoretic layer in an area defined by the partition walls and pixel electrode, wherein the electrophoretic layer is directly on the pixel electrode, and wherein the electrophoretic layer includes a dispersive medium having charged particles; a interlayer on the electrophoretic layer; a common electrode on the second substrate, wherein the common electrode and second substrate are attached to the first substrate, wherein the pixel electrode is extended from an upper surface of the passivation to the lateral side wall of the partition wall to substantially cover the lateral side wall of the partition wall.
