    Abstract: A dielectric adhesive film for an electronic paper display device. A lower electrode to which voltage is applied and an image upper electrode coated with charged particles whose colors are changed depending on the applied voltage are attached to the adhesive film. Thickness of the adhesive film is controlled to be uniform and constant, and a resistance value in the thickness direction of the adhesive film, i.e., a resistance value in the direction where an electric field is formed, is controlled without changing adhesive properties and reliability as the thickness of the adhesive film is controlled. Since loss of the applied voltage is minimized and the charged particles are freely driven, driving performance of the display device is excellent although a high voltage is not applied in driving a flexible display device, such as a flexible LED, an organic electro luminescence (EL) element including an electronic paper, and the like.

    Abstract: The present invention enables a polycondensation reaction of polyester at a low temperature to lead to an improvement in thermal stability as well as a high degree of polymerization in a polyester resin, so that a polyester resin with a minimized end group (carboxyl group) and a small content of foreign matter can be produced. In addition, when a film is manufactured using the polyester resin, a film with a uniform thickness can be produced because no gap is formed between the drum surface and a sheet-like product even at a high rotational speed due to an excellent electrostatic application property and a small melt specific resistance of the polyester resin, and a film with high transparency can be produced due to a small content of foreign matter.
