Patent ID: 7876490

Claim:
A reflection type display apparatus using an electroplating for modulating light comprising: a first electrode; a second electrode; and an electrolyte solution arranged between the first and second electrodes, wherein a first electroplating is formed from the electrolyte solution onto the first electrode by setting a first direction of current flowing between the first and second electrodes, and a second electroplating is formed from the electrolyte solution onto the second electrode by setting a second direction of current flowing between the first and second electrodes, a first surface of the first electroplating is formed on the first electrode such that the first electroplating contacts the first electrode through the first surface and is different in at least one of a light reflectance and a light absorptance from a second surface of the second electroplating formed on the second electrode such that the second electroplating does not contact the second electrode through the second surface, and displaying is performed by a reflection light from the first surface in case that the first electroplating is formed on the first electrode, while displaying is performed by a reflection light from the second surface in case that the second electroplating is formed on the second electrode.
