Abstract
There is provided a driving device of a display device, including: a first switching portion; a second switching portion; and a control section that, when the potential of a drive signal line is lower than a target potential, operates the first switching portion by using, as a 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 is higher than the target potential, operates the second switching portion by using, as a 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.
