A method for manufacturing rotatable two-color particles for a display which is a main component for a display device that may be used in a personal computer, a mobile telephone, and a mobile terminal as well as in a digital paper and a digital book. A display element and a display sheet manufacturing method are also disclosed. The two-color particle manufacturing method includes: a step for bringing, in air or in liquid, a first liquid droplet having a first hue into contact with a second liquid droplet having a hue different from the first hue into a single liquid droplet; and a step for bringing the liquid droplet into contact with a reaction liquid so as to solidify it instantaneously. The two liquid droplets may be injected through a spray nozzle or a jet nozzle. Moreover, the first liquid droplet and the second liquid droplet preferably have different electric charges or different electric charge densities if the charges are identical. Furthermore, the liquid droplets may contain a pigment and a charge control agent.
