ABSTRACT:
An electrophoretic display device is disclosed. The electrophoretic display device includes a plurality of gate lines and a plurality of data lines formed to cross each other on a substrate and define a plurality of pixel regions, a plurality of thin film transistors connected to the respective gate lines and the respective data line on the substrate, an electrophoretic film disposed on the substrate and configured to contain charged particles which are driven in an electrophoresis, color filter patterns disposed on the electrophoretic film and used to realize colors, a protective film adhered with the electrophoretic film by an adhesive material and configured to protect the electrophoretic film, and a sealant formed by dispensing and hardening in a fluid phase on edges of the substrate. The protective film is configured to include an outwardly exposed portion from edges of the electrophoretic film, and a step coverage formed on the exposed portion.
