Abstract:
1. A reflection type display apparatus, comprising: an image display having a plurality of pixels, each of the pixels including a first electrode having a light transmitting property, a second electrode disposed in opposition to the first electrode, a third electrode disposed in opposition to the first or second electrode, and an electrolytic solution containing a metal ion and disposed in contact with the first, second and third electrodes; and a control unit for setting a direction of a current flowing between the first, second and third electrodes, wherein the control unit sets a) a first state of performing 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, such that the first electroplating deposits the metal ion on the first electrode by the electrolytic reduction of the electrolytic solution, b) a second state of performing 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, such that the second electroplating deposits the metal ion on the second electrode by the electrolytic reduction of the electrolytic solution, and c) a third state of performing 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, such that the third electroplating deposits the metal ion on the third electrode by the electrolytic reduction of the electrolytic solution and dissolves at least one of the films formed by the performing of the first and second electroplatings in the electrolytic solution.
