An electrophoretic device includes: a first substrate and a second substrate; an electrophoretic layer including colored particles that is arranged between the first substrate and the second substrate; first electrodes; first transistors connected to the first electrodes; opposing electrodes that have larger areas than the first electrodes and have transparency; and a reflecting layer that has a larger area than the first electrodes, wherein the gradation is controlled by the area of the colored particles that is visible when the electrophoretic layer is seen from the second substrate side.
