Abstract:
1. An electrophoretic display device comprising: a first substrate and a second substrate; an electrophoretic layer that is arranged between the first substrate and the second substrate and that includes at least a dispersion medium and positively or negatively charged colored particles mixed into the dispersion medium; first electrodes that are formed for each pixel on the electrophoretic layer side of the first substrate and that are independently driven for each pixel; first transistors connected to the first electrodes; opposing electrodes that are formed on the electrophoretic layer side of the second substrate, have larger areas than the first electrodes, and have transparency; and a reflecting layer that is formed over the first substrate, reflects light, and that has a larger area than the first electrodes, wherein the gradation is controlled by an area of the colored particles that is visible when the electrophoretic layer is seen from the second substrate side.
