Abstract
A display device including a display panel including a scan line, a data line, and a pixel connected thereto, a gate driver, and a source driver including a gamma voltage generator to generate gamma voltages having different voltage levels, a digital-to-analog converter to generate the data voltage corresponding to a gray scale value using the gamma voltages, and a source buffer, in which the gamma voltage generator includes a first resistor string to set a voltage range of the gamma voltages, a second resistor string to set tab gamma voltages corresponding to some of the gamma voltages within the voltage range, gamma buffers to output the tab gamma voltages, and a third resistor string including tabs respectively connected to output terminals of the gamma buffers, the third resistor string being configured to divide a voltage between the tabs to generate the gamma voltages.
