A display device includes light-emitting elements, current control elements, a power supply circuit, and a voltage control circuit. The current control elements are connected in series with the corresponding light-emitting elements and control current through the light-emitting elements. The power supply circuit applies a voltage to a series circuit that includes the light-emitting elements and the current control elements. The voltage control circuit controls an output voltage of the power supply circuit to reach a voltage value determined in accordance with forward voltages of the light-emitting elements.
