1. An electrophoretic display device comprising:
- a substrate;
a gate line on the substrate;
a data line being intersected with the gate line, wherein the gate line and the data line form a pixel region;
a thin film transistor being disposed in the pixel region;
a common line being parallel with the gate line;
a protective layer covering the gate line, the data line, the thin film transistor and the common line;
a capacitor upper electrode being connected to a drain electrode of the thin film transistor;
a first electrode disposed on the protective layer, including;
a plurality of first patterns separated from each other; and
a second pattern electrically connected to and crossing the plurality of first patterns within the pixel region;
an electrophoretic film disposed on the first electrode; and
a second electrode disposed on the electrophoretic film,wherein the first patterns are disposed laterally with each other,wherein the capacitor upper electrode overlaps with the first patterns and the second pattern,wherein the capacitor upper electrode and the common line form a capacitor,wherein the capacitor overlaps with the first patterns, andwherein the second pattern is connected with the capacitor upper electrode through a contact hole formed at the protective layer.

Abstract
An electrophoretic display device is described. The device includes a substrate, first electrodes, an electrophoretic film having electrophoretic particles, and second electrodes. The substrate is has a plurality of pixel regions. First electrodes are disposed respectively on each pixel region, and include first patterns separated from one another and second patterns connected to the first patterns. The second electrode is disposed on the electrophoretic film. The area of one of the electrodes, opposing the other of the electrodes has apertures formed therein, reducing the contact area between the electrode and the electrophoretic film.
