<p>This display device is provided with the following: a variable voltage source (180) that outputs a high-potential-side output potential and/or a low-potential-side output potential; an organic EL display unit (510) in which a plurality of light-emitting pixels are arrayed; a potential-difference detection circuit (170A) that detects the electric potential of said light-emitting pixels; and a signal processing circuit (160) that adjusts the output potential of the variable voltage source (180) so as to bring the difference between the electric potential of the light-emitting pixels and a reference potential to a prescribed level. The power-supply wiring resistance between light-emitting pixels adjacent in a first direction is higher than that between light-emitting pixels adjacent in a second direction, and the mean separation between potential-detection points adjacent in the first direction is shorter than that between potential-detection points adjacent in the second direction.</p>
