Patent ID: 8482514

Claim:
An electrophoretic display device comprising: an ink substrate including: a first substrate having a first surface and a second surface opposing the first surface, an electrode adjacent the first surface of the first substrate, an ink layer adjacent the electrode, the ink layer including a plurality of microcapsules; a first protective member disposed and cured to form a sealed ink layer by contacting side surfaces of the first substrate, the electrode, the ink layer; a second protective member disposed and cured on an outer surface of the first protective member, wherein the first protective member is made of a material different from that of the second protective member; and a driving substrate attached to the ink layer of the ink substrate, the driving substrate including a second substrate and a plurality of driving devices disposed thereon, a protective film formed on the second surface of the first substrate; wherein the first protective member and the second protective member extend between the driving substrate and the protective film and do not extend beyond the first substrate and the ink layer, the first and second protective members contacting the driving substrate and the protective film, and wherein the first protective member is disposed and cured to form the sealed ink layer prior to the driving substrate being attached to the ink substrate.
