Abstract
A display device capable of decreasing an amplifier offset using a gate-start pulse signal is disclosed. A display device includes a display panel, a control circuit, a gate driving circuit and a source driving circuit. The source driving circuit includes a plurality of source driving chips, compensates for an amplifier offset in response to the gate-start pulse signal, performs digital-to-analog (D/A) conversion on data received from the control circuit using gray scale voltages in response to the source control signal, and provides the converted data to the source lines.
