PROBLEM TO BE SOLVED: To provide liquid for electrophoresis display for reversibly changing a visible state by the action of an electric field or the like, and to provide a display medium and a display device using the liquid. SOLUTION: The liquid for the electrophoresis display is characterized in that it contains at least oxidization polyethylene particles, alkyl polyether amine having a structural unit denoted by general formula (I), one or more particulates and a dispersion liquid medium. In addition, the electrophoresis display medium is characterized in that the liquid for the electrophoresis display is sealed in a structure in which each of capsules or cells is independent. Furthermore, the electrophoresis display device is characterized in that it consists of a pair of substrates forming an electrode having optical transmittance on at least one hand, and of the electrophoresis display medium between the substrates. The electrophoresis display device is superior in dispersion stability in secular preservation, has high contrast of a display face, can display in contrast with high reliability, and is superior in low voltage driving and advancement of a response speed.
