Abstract:
1. A display device comprising: a display layer that is provided with a cell in which first particles, second particles, and third particles with different colors from one another are contained; a front side electrode that is provided on the front side of the display layer; and a first back side electrode and a second back side electrode that are provided corresponding to the cell on the back side of the display layer, wherein the first particles are positively or negatively charged, wherein the second particles have 1) a color with a complementary color relation to that of the first particles, 2) an opposite polarity charge to that of the first particles, and 3) a smaller amount of charge than that of the first particles, and a voltage application pattern to the front side electrode, the first back side electrode, and the second back side electrode is selected and the selected voltage pattern is applied, and then the first particles and the second particles are disproportionately located with the third particles are dispersed in the cell, to change a displayed color from the front side,
