Electropheretic display device and method for manufacturing the same

A method for manufacturing an electrophoretic display device, comprising:

• forming a thin film transistor on a lower substrate;
• forming a pixel electrode connected to the thin film transistor;
• forming an electronic ink layer on the pixel electrode;
• etching an upper substrate to form a groove and a partition;
• forming a reflecting layer on the partition;
• forming a color filter in the groove;
• forming an adhesive layer on the reflecting layer and the color filter;
• and
• adhering the adhesive layer to the electronic ink layer.
