Patent ID: 7855828

Claim:
A manufacturing method of an electrophoretic display device, the manufacturing method comprising: forming a first mother substrate that has a first thin structure; forming a second mother substrate that has a second thin structure, wherein the second mother substrate faces the first mother substrate; disposing an electrophoretic material on one of the first mother substrate and the second mother substrate; enclosing a region on which the electrophoretic material is disposed with a sealant; and combining the first mother substrate and the second mother substrate using pressure applied thereto, while forming an electrophoretic layer between the first mother substrate and the second mother substrate, wherein the formation of the first mother substrate comprises: forming a gate electrode on a substrate; forming a semiconductor on the gate electrode; forming a source electrode and a drain electrode on the semiconductor; and forming a pixel electrode on the source electrode and the drain electrode, the pixel electrode being connected to the drain electrode.
