Abstract
A data driving circuit and a display device are provided. A display device includes: a display panel including a plurality of subpixels, each of the plurality of subpixels including: a light-emitting device, and a driving transistor configured to drive the light-emitting device, and a data driving circuit configured to: supply a data voltage to the plurality of subpixels, and supply, in a display period, to at least one subpixel among the plurality of subpixels: the data voltage, obtained by adding a first voltage corresponding to a luminance of the light-emitting device, and a second voltage smaller than a change value of a threshold voltage of the driving transistor.
