Abstract
A display device is provided that effectively reduces noise generated inside a display panel such as a liquid crystal panel. The source driving unit of the display device includes positive amplifiers, negative amplifiers, a positive amplifier regulating unit and a negative amplifier regulating unit. The positive amplifiers transmit positive driving signals to the display panel unit via source lines. The negative amplifiers transmit negative driving signals to the display panel via source lines. The positive amplifier regulating unit regulates the timing for the positive amplifiers to output positive driving signals. The negative amplifier regulating unit regulates the timing for the negative amplifiers to output negative driving signals.
