FIG. 1 is a block diagram of a display device constructed according to an exemplary embodiment of the invention. As shown in FIG. 1, a display device includes a display portion 10 that includes a plurality of pixels PX, a scan driver 20, a data driver 30, a power supply portion 40, and a controller 50.

The plurality of pixels PX included in the display portion are arranged substantially in a matrix format. Although it is not particularly limited, a plurality of scan lines S1 to Sn extend substantially in a row direction in the matrix format of the pixels and are substantially parallel with each other, and a plurality of data lines D1 to Dm substantially extend in a column direction and are substantially parallel with each other.
