A display device includes a display panel having first and second areas adjacent to each other, and a distribution unit configured to generate first and second input image data from primitive image data. The display device includes a first control unit having a first sub-pixel rendering unit configured to receive the first input image data and to generate first rendering data by performing sub-pixel rendering on the first input image data. The display device further includes a second control unit having a second sub-pixel rendering unit configured to receive the second input image data and to generate second rendering data by performing sub-pixel rendering on the second input image data. The display device includes an extraction unit configured to extract from the first rendering data, first output data corresponding to the first area, and from the second rendering data, second output data corresponding to the second area.
