Abstract
A display device has a display panel including gate lines, a driving circuit, and an auxiliary circuit corresponding to each gate lines. To the driving circuit and the auxiliary circuit, one driving signal of M-phase driving signals (M≥4) having selection potential and non-selection potential, is supplied. The driving circuit outputs the driving signal to a corresponding gate line. A selection period for the gate line includes a pre-charging period and a main charging period, and the main charging period overlaps with the pre-charging period for the adjacent gate line. The auxiliary circuit is driven during the main charging period for the corresponding gate line and during the main charging period for the next gate line. The auxiliary circuit outputs the selection potential during the main charging period for the corresponding gate line, and outputs the non-selection potential during the main charging period for the next gate line.
