Abstract
Embodiments of the disclosure relate to a display device and a data driving circuit. Specifically, there may be provided a display device with enhanced power efficiency and a data driving circuit by providing a display device including a display panel divided into an always-on display area displaying information during a standby screen period and a black grayscale area except for the always-on display area, an image display voltage output circuit outputting a data voltage to input to the always-on display area during the standby screen period, and a voltage stabilization circuit outputting a constant voltage to input to at least a partial area of the black grayscale area during the standby screen period.
