Abstract: A display device includes a display panel, a gray-scale voltage generator, and a data driver. The data driver includes a first amplifier. The first amplifier includes a first voltage input terminal configured to receive a first voltage, a second voltage input terminal configured to receive a second voltage lower than both the first voltage and a common voltage to be applied to a pixel included in the display panel, an input terminal configured to receive a gray-scale voltage having a gray-scale level corresponding to image data, and an output terminal configured to output the data voltage as a buffered voltage corresponding to the gray-scale voltage.
