Abstract: A display driving circuit and a display device including the display driving circuit are disclosed. The display driving circuit includes: a data driver including a first channel amplifier operating based on first pixel data and a second channel amplifier operating based on second pixel data and configured to drive first and second pixels of a display panel based on the first pixel data and the second pixel data of a first line; and a data comparator configured to compare the first pixel data with the second pixel data and determine operation states of the first channel amplifier and the second channel amplifier on a comparison result, before a first horizontal period in which the first pixel and the second pixel are driven.
