Abstract: A display device includes a display panel including a first data line, a second data line, and a pixel, the pixel including a first sub-pixel coupled to the first data line, and a second sub-pixel coupled to the second data line, a light stress compensator configured to generate a first data voltage control signal for the first sub-pixel based on a second data value of input image data for the second sub-pixel, in response to a first data value of input image data for the first sub-pixel being equal to or less than a first reference value, and a data driver configured to generate a first data signal based on the first data value for the first sub-pixel, to provide a first data voltage to the first data line, and to vary the first data voltage based on the first data voltage control signal.
