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.

Description

technical field [0001] The present disclosure relates to an electrophoretic display (EPD) device and a manufacturing method thereof, and more particularly, to an electrophoretic display device suitable for preventing a sealant from entering a non-active area and a manufacturing method thereof. Background technique [0002] This application claims priority from Korean Patent Application No. 10-2008-132730 filed on December 23, 2008, the entire contents of which are hereby incorporated by reference. [0003] In general, an electrophoretic display (EPD) device is a reflective display device capable of repeatedly writing and erasing images and letters using an electrophoretic phenomenon. In other words, the EPD moves charged particles dispersed in a fluid substance in accordance with an applied electric field to display images or letters. [0004] EPDs can be made very thin, and typically retain their display properties even when, for example, paper is bent. In addition, EPDs ...
