1. A display device comprising:
a plurality of pixels;
a plurality of scan lines extending in a row direction and connected to the plurality of pixels;
a plurality of data lines extending in a column direction and connected to the plurality of pixels;
a plurality of receiving lines extending in the column direction and connected to the plurality of pixels; and
a compensation circuit portion connected to the plurality of receiving lines,
wherein the compensation circuit portion includes:
a plurality of sensing data generating circuits each of which generates a first sensing data by sensing current flowing through a receiving line,
a calibration factor generator receiving the first sensing data and generating a calibration factor corresponds to a position of each of the plurality of pixels, and
a calibration operation portion receiving the first sensing data and generating a compensation value compensating a characteristic of a driving transistor included in each of the plurality of pixels,
wherein the calibration factor comprises a plurality of line calibration factors corresponding to the plurality of receiving lines, and
wherein deviations exist in average first sensing data of a factor detection area according to the plurality of receiving lines.
