  • Patent number: 8446662
    Abstract: A method of manufacturing is disclosed for an electrophoretic display apparatus that includes an array substrate and an electrophoretic film laminated to the array substrate. A thermally activated adhesive is used to adhesively attach the electrophoretic film to the array substrate. The electrophoretic film is first aligned to and flattened against the array substrate and then a substantially stronger than original adhesion property of the adhesive is activated by annealing at a high temperature that is substantially greater than room temperature. Rework prior to annealing is therefore possible when alignment errors occur between the electrophoretic film and the array substrate.

    Abstract: An electrophoretic display panel includes a first member, a second member, an electrophoretic layer and an outer member. The first member includes a first substrate and a pixel electrode formed on the first substrate. The first substrate has a display area and a dummy area disposed outside of the display area. The second member includes a second substrate facing the first substrate and a common electrode formed on a first surface of the second substrate. The electrophoretic layer is disposed between the first member and the second member and displays an image by an electric field generated between the pixel electrode and the common electrode. The outer member covers the dummy area and blocks light, so that display quality is improved.
