14. A display device, comprising:
a display panel comprising a first display area and a second display area adjacent to the first display area; and
a panel driver receiving image data and controlling the display panel based on the image data,
wherein a plurality of reference units is disposed in the second display area, each of the reference units comprises n first color light emitting elements, a first driving circuit connected to the n first color light emitting elements by a first connection line, m second color light emitting elements, a first sub-driving circuit connected to k second color light emitting elements among the m second color light emitting elements by a second connection line, and a second sub-driving circuit connected to j second color light emitting elements among the m second color light emitting elements by a third connection line, each of the n and the m is a natural number greater than 1, the m is greater than the n, each of the k and the j is a natural number equal to or greater than 1 and smaller than the m, and
the panel driver renders n first color image data corresponding to the n first color light emitting elements to generate first color compensation data for one among the n first color light emitting elements and renders m second color image data corresponding to the m second color light emitting elements to generate first sub-compensation data for a first one among the m second color light emitting elements and second sub-compensation data for a second one among the m second color light emitting elements,
wherein the first driving circuit receives a first data signal corresponding to the first color compensation data through a first data line of the display panel to commonly provide the first data signal to the n first color light emitting elements through the first connection line,
the first sub-driving circuit receives a first sub-data signal corresponding to the first sub-compensation data through a second data line of the display panel to commonly provide the first sub-data signal to the first one among the m second color light emitting elements through the second connection line, and
the second sub-driving circuit receives a second sub-data signal corresponding to the second sub-compensation data through a third data line of the display panel to commonly provide the second sub-data signal to the second one among the m second color light emitting elements through the third connection line.
