Abstract: A display device includes: a display panel configured to display an image corresponding to an image signal, and including pads; and a driving chip configured to provide data signals to the pads. The driving chip includes: an analog part configured to convert an input voltage received through an input line into a driving voltage, and convert an image data signal into the data signals; and buffers configured to receive a buffer voltage through a buffer line that is different from the input line, and output the data signals to the pads.
