ABSTRACT:
A plurality of cells are set apart by a spacer member between a display plate and a rear face plate. Black particles with positive static charge and white particles with negative static charge are dispersed in a dispersion fluid, which is enclosed in the cells. A red colored layer and electrodes7a, 7band7care formed at the rear face plate. When a voltage of +50 V is applied to the electrode7a, 0 V to7band −50 V to7c, the black particles move to the electrode7c, the white particles move to the electrode7a, and red can be viewed. When a voltage of +50 V is applied to the electrode7a, 0 V to7band +50 V to7c, the white particles move to the electrode7a, the black particles move to the electrode7b, and black can be viewed. When a voltage of −50 V is applied to the electrode7a, 0 V to7band −50 V to7c, the black particles move to the electrode7c, the white particles move to the electrode7b, and white can be viewed.
