• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PURPOSE: An electrophoretic display device and a manufacturing method thereof are provided to prevent the performance degradation of the electrophoretic display device by dually preventing moisture from permeating into an electrophoretic film. CONSTITUTION: A first sealant(5) seals a part between an electrophoretic film(22) and a protective sheet(3) and a part between a substrate(21) and the electrophoretic film. A second sealant(6) seals a part between the substrate and a circuit film(4). A protrusion member(211) of the substrate supports the second sealant. The protrusion member includes a groove(212) for the second sealant. The second sealant is placed on the groove between the protrusion member and the circuit film.
