An electronic ink panel, capable of displaying full colour gradation without a colour filter, comprises: an electronic ink layer (210) comprising first to third particle types (222, 224, 226); a first substrate (202) in which a first electrode (206) facing one surface of the electronic ink layer (210) is formed; and a second substrate (204) facing the first substrate with second electrodes (208) defining pixel regions. The particle types may be red, green and blue particles where each colour responds to voltages in a different range. A plurality of capsules each contain a fluid suspending some of each particle type, the position of the capsules being fixed by a binder film. A gamma voltage generating section 240 applies gamma voltages 242, 244, 246 in three different ranges, to cause one of the types of particles to perform electrophoresis and hence to change the colour of the pixel regions to which the voltage is applied. |
