Abstract
A display device includes a display panel including a first pixel and a second pixel, a reference gamma generator configured to generate a first reference gamma voltage and a second reference gamma voltage based on a driving mode, a stain compensator configured to output a stain compensating data that compensates a stain of an image data based on the driving mode, and a data driver configured to generate a first data voltage provided to the first pixel based on the first reference gamma voltage and the stain compensating data and a second data voltage provided to the second pixel based on the second reference gamma voltage and the stain compensating data.
