Abstract:
A reflection type display apparatus includes an image display having a plurality of pixels, with each of the pixels including a first electrode having a light transmitting property, a second electrode disposed in opposition to the first electrode, and a third electrode disposed in opposition to the first or second electrode. An electrolytic solution containing a metal ion is disposed in contact with the first, second and third electrodes, and a control unit sets a direction of a current flowing between the first, second and third electrodes. The control unit sets a first state of forming a first electroplating of a first color on the first electrode using the first electrode as a negative electrode and using the second electrode as a positive electrode, a second state of forming a second electroplating of a second color on the second electrode using the second electrode as the negative electrode and using the first electrode as the positive electrode without forming the first electroplating, and a third state of forming a third electroplating of a third color on the third electrode using the third electrode as the negative electrode and using the first and second electrodes as the positive electrodes without forming the first and second electroplatings.
