<p>Provided is a display device that appropriately addresses the fluctuation and changes over time of the luminance of light emitting pixels, and has a low cost and has an excellent power-consumption reducing effect; also provided is a driving method therefor. The display device comprises: an organic EL display unit (110) in which a plurality of light-emitting pixels are disposed; a variable voltage generator (180) that supplies positive supply potential and negative supply potential to the display unit; and a calculation circuit (170) for measuring the anode potential and the cathode potential of a representative light-emitting pixel. The variable voltage generator (180) adjusts the positive electrode supply potential with respect to the negative electrode supply potential, in accordance with at least the potential difference between the negative supply potential of the variable voltage generator (180) and the cathode potential of the representative pixel, and outputs the results to the organic EL display unit (110).</p> |
