Display apparatus and driving method for the same

An apparatus comprising:

• a plurality of light emitting elements configured to emit light of colors assigned to respective light emitting elements by providing currents flowing between first and second electrodes;
• a plurality of driving circuits connected to the first electrodes of the light emitting elements to supply currents thereto;
• and
• a plurality of power supply lines connected to the second electrodes of the light emitting elements to supply voltages to the second electrodes,
• wherein a set of the light emitting elements that emit light of colors different from each other are connected such that the first electrodes are connected in common to one of the driving circuits, and the second electrodes are separately connected to the plurality of the power supply lines,
• and wherein the light emitting elements whose second electrodes are connected to one of the power supply lines include light emitting elements configured to emit light of different colors.
