One embodiment of the present invention is a multi-color display panel, including: a transparent substrate, a color filter layer, a transparent electrode layer, a microcapsule layer, an adhesive layer, a rear electrode plate, wherein the transparent substrate, the color filter layer, the transparent electrode layer, the microcapsule layer the adhesive layer and the rear electrode plate are arranged in this order, the microcapsule layer is directly formed on the transparent electrode layer, the microcapsule layer has a structure in which microcapsules are dispersed in a binder resin, a dispersion liquid in which an electrophoresis particle is dispersed in a transparent dispersion medium is enclosed in the microcapsule, and an optical reflection property of the microcapsule changes according to a change of electric field by application of a voltage, and wherein the electrode plate has a rear substrate with a pixel electrode.

Multi color display panel and method for manufacturing the same

One embodiment of the present invention is a multi color display panel, having a transparent substrate, a color filter layer, a transparent electrode layer, a microcapsule layer, an adhesive layer; and a rear electrode plate, wherein the rear electrode plate is an electrode plate in which a pixel electrode is arranged on a substrate, a film thickness of the color filter layer is 0.5-2.0 &#x3bc;m, a step between pixels or inside a pixel inside a display screen, the step being difference of the film thickness, is equal to or less than 0.3 &#x3bc;m, one of the pixels does not overlap an adjacent pixel, and a top edge of each of the pixels of a trapezoid shape is within 5.0 &#x3bc;m from a border of the pixel.

Multi color display panel

One embodiment of the present invention is a color electrophoresis type display medium panel having a transparent substrate, a color filter layer, a transparent electrode layer, a microcapsule layer, an adhesive layer and a rear electrode plate, wherein the microcapsule particle has a specific distribution wherein an average particle diameter of the microcapsule in a direction observed from a viewer is defined as X, and an average particle diameter of the microcapsule in another direction perpendicular to the direction observed from a viewer is defined as Y.
