PROBLEM TO BE SOLVED: To allow for easy and precise gradation control of a target pixel.SOLUTION: A drive circuit of an electrophoretic display device includes the steps of: applying a first voltage pulse to a target pixel for only the number of times determined according to a target gradation of the pixel to thereby cause the pixel to transit to a first display state; and applying, for only the number of times according to a gradation distance to the target gradation, a second voltage pulse that has a reverse polarity to that of the first voltage pulse and a smaller amount of change in gradation per scan than the first voltage pulse if the direction of the target gradation is opposite to the direction of gradation changed by the first voltage pulse when viewed from the first display state. The drive circuit further includes a step of applying, for only the number of times according to the gradation distance to the target gradation, a third voltage pulse that has the same polarity as that of the first voltage pulse and a smaller amount of change in gradation per scan than the first voltage pulse if the direction of the target gradation is same as the direction of gradation changed by the first voltage pulse when viewed from the first display state. |
