Abstract
Provided is an electrophoretic display device including: an electrophoretic panel which is provided with an electrophoretic element which includes a first electrode, a second electrode which faces the first electrode, and a charged particle arranged between the first electrode and the second electrode; and a control circuit which controls the electrophoretic panel. The control circuit controls a data voltage with a value which corresponds to the specified gradation of the electrophoretic element to be applied between the first electrode and the second electrode in a writing period, and controls a correction voltage which is the opposite polarity to the data voltage and is less than or equal to a predetermined threshold value to be applied between the first electrode and the second electrode in a correction period which is different from the writing period.
