Electrophoretic display device

An electrophoretic display device, comprising:

• a first substrate;
• an electrophoretic display film disposed on the first substrate and comprising a display medium layer and a first electrode;
• a plurality of second electrodes separately disposed on the first substrate and located between the display medium layer and the first substrate, a first voltage received by each of the second electrodes is controlled by a corresponding thin-film transistor;
• and
• a plurality of third electrodes disposed on the first substrate and located between the display medium layer and the first substrate, wherein the third electrodes and the second electrodes are alternately disposed in a direction, the first voltage is different from a second voltage received by the third electrodes, and the third electrodes are a plurality of barrier electrodes which are not controlled by thin-film transistors under the display medium layer,
• wherein the first electrode receives the second voltage,
• wherein the second electrodes and the third electrodes are disposed at a same level,
• wherein the display medium layer comprises an electrophoretic fluid and a plurality of charged particles distributed in the electrophoretic fluid, and the charged particles are moved vertically,
• wherein a width of each of the third electrodes is less than a horizontal spacing between each of the third electrodes and the two adjacent second electrodes,
• wherein the electrophoretic display film further comprises a second substrate, the first electrode is disposed on a whole lower surface of the second substrate, the first electrode is located between the second substrate and the display medium layer, an area of orthographic projection of the first electrode on the first substrate is greater than an area of orthographic projection of the third electrode on the first substrate, and no electric field is generated between the third electrodes and the first electrode.
