Abstract
A display device having a charging compensation circuit to reduce/eliminate display stains based on pixels being charged at unequal charging rates. A data driving circuit of a display device includes an output circuit for converting an image signal into a data signal in response to a clock signal, and providing the data signal to a plurality of data lines, and a clock generating and compensating circuit for receiving a main clock signal and generating the clock signal, wherein the clock generating and compensating circuit detects a slew rate of the data signal provided to at least one of the plurality of data lines, and adjusts a phase of the clock signal depending on the detected slew rate.
