Driving device of display device

A driving device of a display device, comprising:

• a first switching portion that is provided between a potential switching portion, that switches a potential of a drive signal line to a target potential that corresponds to display data, and a display device, to which the potential of the drive signal line is supplied as voltage, the first switching portion connecting the drive signal line to a power source during a time until the potential of the drive signal line reaches a first reference potential that is higher than a potential of the drive signal line during a previous cycle;
• a second switching portion that is provided between the potential switching portion and the display device, and that connects the drive signal line to a ground line during a time until the potential of the drive signal line reaches a second reference potential that is lower than a potential of the drive signal line during the previous cycle;
• and
• a control section that, when the potential of the drive signal line during the previous cycle is lower than the target potential, operates the first switching portion by using, as the first reference potential, a potential that is less than or equal to the target potential and that is closest to the target potential, among predetermined n types (n≧1) of potentials, and, when the potential of the drive signal line during the previous cycle is higher than the target potential, operates the second switching portion by using, as the second reference potential, a potential that is greater than or equal to the target potential and that is closest to the target potential, among the n types of potentials.
