Patent ID: 7898727

Claim:
An electrophoretic display device comprising: 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, wherein 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, wherein the exposed portion provided with the step coverage is formed thinner than the rest of the protective film, wherein the step coverage is formed to have a height range of about 40˜140 μm, wherein the exposed portion is formed in an inwardly inclined shape toward an inner side of the protective film.
