ABSTRACT:
An electrophoretic display (EPD) device adapted to prevent a dispensed fluid sealant from moving toward a non-active area is disclosed. The EPD device includes: a first substrate configured to include a flexible plate divided into an active area and a non-active area; a thin film transistor array formed on the active area of the plate; a second substrate opposite to the first substrate; an electrophoretic film, between the first and second substrates, configured to contain charged particles driven depending on electrophoresis; a sealant, between the first and second substrates, hardened from fluid state; a sealant block formed on a sealant formation region to prevent the fluid sealant from flowing into the non-active area before hardening of the fluid sealant, wherein the sealant block is configured to include a first dam, a second dam, and a furrow between the first and second dams.
