Abstract
In an embodiment of the present disclosure, there is provided a display device including: a plurality of subpixels between a line of a first power voltage and a line of a second power voltage, the plurality of subpixels configured to be supplied with a driving current and to emit light in response to the driving current; and a power supply unit configured to generate the first power voltage and the second power voltage based on an external input voltage, wherein the power supply unit generates power when the external input voltage corresponds to between a preset maximum voltage and a minimum voltage, and the power supply unit reduces a voltage difference between the first power voltage and the second power voltage when the external input voltage corresponds to between a preset reference voltage and the minimum voltage.
