Abstract
A display device is disclosed. The display device includes a display panel including data lines, panel lines, scan lines, and pixels, a power circuit configured to output a reference voltage for initializing subpixels of the pixels, a plurality of branch lines configured to divide a path of the reference voltage into a plurality of paths, and a switch circuit configured to switch a path between the branch lines and the panel lines in response to a switch control signal. The switch circuit changes the path between the branch lines and the panel lines at intervals of predetermined time.
