A data driving circuit for displaying uniform images, a light emitting display device using the same, a driving method thereof. The data driving circuit includes a holding latch part including a plurality of holding latches for storing data, a signal generation part including a plurality of digital-analog converters for receiving the data and for generating data signals, a first switching part located between the holding latch part and the signal generation part, and a second switching part electrically connected to the signal generation part, the second switching part being for transmitting the data signals to data lines, wherein the first switching part electrically connects the respective holding latches to the respective digital-analog converters differently during a previous frame than during a current frame. As such, the data driving circuit may diffuse errors of the digital-analog converters to display uniform images.
