Abstract

The present invention is directed to an electrophoretic slurry composition and an electrophoretic display device comprising the same, where the electrophoretic slurry comprises charged particles; polymer beads comprising an acryl- or vinyl-based repeating unit; and a fluid medium. Accordingly, the present invention has a high reactivity to a driving voltage, sustains images or text for a predetermined period of time or longer even when the driving voltage is switched off, and provides a high contrast ratio and enhanced visibility to implement high-quality text or images.
