<p>This display device (100) is provided with: a variable voltage source (180) which outputs an output potential on a high potential side and a low potential side; an organic EL display unit (110) comprising an arrangement of multiple light-emitting pixels; a potential difference detection circuit (170) for detecting the potential on the high potential side of light-emitting pixels (111MA) and the potential on the low potential side of light-emitting pixels (111MB); and a signal processing circuit (160) which adjusts the output potentials on the high potential side and/or the low potential side outputted from the variable voltage source (180) such that the potential difference between the potential on the high potential side of the light-emitting pixels (111MA) and the potential on the low potential side of the light-emitting pixels (111MB) assumes a prescribed potential difference.</p>
