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.
