Abstract

The display device includes a first data line group including data lines connected to pixels arranged at a first resolution; a second data line group including data lines connected to pixels arranged at the first resolution and pixels arranged at a second resolution; a first gamma compensation voltage generation unit that divides a first reference voltage and outputs a gamma compensation voltage; a second gamma compensation voltage generation unit that divides a second reference voltage and outputs gamma compensation voltages; a first data drive unit that converts pixel data into the gamma compensation voltage output from the first gamma compensation voltage generation unit and outputs a data voltage to the first data line group; and a second data drive unit that converts pixel data into the gamma compensation voltage output from the second gamma compensation voltage generation unit and outputs a data voltage to the second data line group.
