Display device

A display device comprising:

• a power supplying unit configured to output at least one of a high-side output potential and a low-side output potential;
• a display unit in which pixels are arranged and which receives power supply from the power supplying unit;
• a voltage detecting unit configured to detect at least one of a high-side applied potential to be applied to at least one of the pixels in the display unit and a low-side applied potential to be applied to at least one of the pixels in the display unit which is the same as or different from the at least one of the pixels to which the high-side applied potential is to be applied;
• a voltage regulating unit configured to regulate at least one of the high-side output potential and the low-side output potential outputted by the power supplying unit to set, to a predetermined potential difference, a potential difference between (i) at least one of the high-side applied potential and the low-side applied potential and (ii) a reference potential;
• and
• at least one of:
• a high-side potential detecting line having one end connected to the at least one pixel for which the high-side applied potential is detected and the other end connected to the voltage detecting unit, for transmitting the high-side applied potential to the voltage detecting unit;
• and
• a low-side potential detecting line having one end connected to the at least one pixel for which the low-side applied potential is detected and the other end connected to the voltage detecting unit, for transmitting the low-side applied potential to the voltage detecting unit.
