A display device according to the present disclosure includes: a variable-voltage source which outputs a high-side output potential and a low-side output potential; an organic electroluminescence (EL) display unit in which a plurality of pixels are arranged; a potential difference detecting circuit which detects a high-side potential of a first pixel and a low-side potential of a second pixel; and a signal processing circuit which regulates at least one of the high-side output potential and the low-side output potential outputted from the variable-voltage source such that a potential difference between the high-side potential of the first pixel and the low-side potential of the second pixel reaches a predetermined potential difference.
