Patent ID: 7729040

Claim:
An electrophoretic display device comprising: a first substrate having a plurality of pixel electrodes in a display region thereof, a distance between neighboring pixel electrodes among the plurality of pixel electrodes being 5 μm or more, the plurality of pixel electrodes being a plurality of segment electrodes arranged in a specified pattern; a through hole provided for each of the plurality of segment electrodes in such a manner as to extend through the first substrate and one of the segment electrodes, at a position that overlaps the segment electrode in plan view; a connecting part, formed along and covering an inner surface of the through hole, one end of which is connected to the segment electrode and the other end of which is connected to a surface of the first substrate opposite a surface having the pixel electrodes, the connecting part having a continuous hole that continues from the one end to the other end of the connecting part, located at a central portion of the connecting part in plan view, the continuous hole having a diameter of 100 μm or less; and an electrophoretic sheet that includes a second substrate on which a common electrode, an electrophoretic layer, and an adhesive layer are laminated, the electrophoretic sheet being bonded to the display region of the first substrate via the adhesive layer.
