A dielectric adhesive film for an electronic paper display device, by which the operating performance of a flexible display device is excellent even applying a high voltage when the flexible display device is operated, by controlling a dielectric constant with respect to an adhesive film for attaching a lower electrode to which a voltage is applied with an image upper electrode on which particles, which possess electric charges with various colors that change according to an applied voltage, are coated to adjust the electric charges of the adhesive film in the thickness direction to thereby minimize loss of the applied voltage while maintaining an adhesive property and reliability.

Disclosed is an optical-modulation object, including birefringent island-in-the-sea yarns, whose island portions are grouped, based on two or more spinning cores, in a matrix. The optical-modulation object causes formation of an optical modulation interface between island portions and sea portions, thus maximizing optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns.
