Abstract
Discussed is a display device including a display panel including first and second display areas that differ in the number of sub-pixels per unit area, a data driver that generates data voltages, and supplies the data voltages to the sub-pixels in the corresponding areas, and a power supply part that generates first display area high-potential power for the first display area and second display area high-potential power for the second display area, and supplies the first and second display area high-potential powers to the corresponding display areas. Each of the sub-pixels includes a switching transistor connected to a gate line and a data line, and a pixel circuit including a driving transistor that is turned on in response to a data voltage stored in a storage capacitor, and supplies a driving current to an organic light-emitting diode positioned between a first power line and a second power line.
