Abstract: Disclosed is a display device including a pixel and a first scan driving circuit that applies a write scan signal to the pixel in response to a write clock signal. The first scan driving circuit outputs the write scan signal having a first operating frequency in a normal mode, and outputs the write scan signal having a second operating frequency lower than the first operating frequency in a low-frequency mode. The write clock signal has a direct current (DC) level in the low-frequency mode in response to a first set signal applied to the first scan driving circuit.
