  • Patent number: 10416523
    Abstract: A electrophoretic display device manufacturing method includes bonding a substrate including a pixel electrode and a stacked film including a transparent electrode layer and an electrophoretic display layer, and forming a color filter layer having a pixel pattern corresponding to a pattern of the pixel electrode above a base material surface of the stacked film. The substrate has a region where the electrophoretic display layer is not arranged when the substrate and the stacked film are bonded, a pixel alignment pattern is drawn in the region, and in the forming the color filter layer, the color filter layer is formed while performing alignment using the pixel alignment pattern.

  • Publication number: 20180277573
    Abstract: A display device includes a base material having a first surface, a thin-film transistor layer formed on the first surface, a display layer formed on the thin-film transistor layer such that the display layer covers the thin-film transistor layer, a first barrier film formed on the base material and the display layer, the first barrier film having an area larger than the display layer such that the first barrier film covers the display layer, and a driver-mounting electrode formed on the first surface of the base material. The first barrier film is formed such that the first barrier film surrounds plural sides of the driver-mounting electrode in a plan view.

  • Patent number: 9874798
    Abstract: An electrophoretic display substrate includes an electrophoretic display layer which is interposed between a first substrate and a second substrate and includes at least one electrophoretic ink display element which is charged. The first substrate includes a thin film transistor, a sub pixel electrode, a capacitor element including a first electrode and a second electrode, capacitor element electrode lines connected to the second electrode, and common electrode lines. The second substrate has a first surface on which a common electrode is formed and a second surface on which a color filter layer is formed. The common electrode is connected to the common electrode lines of the first substrate. The color filter layer includes a transparent resin which is laminated on the second substrate and color filter pixels which are formed on the transparent resin.
