PROBLEM TO BE SOLVED: To efficiently suppress variations of display characteristics among liquid crystal panels. SOLUTION: The driving circuit 30 of the liquid crystal display device applies driving voltages VCOM1, VCOM2 to common electrodes 6, 7 disposed for a plurality of pixels 1 of a liquid crystal panel 20 in common. The driving circuit 30 is provided with: a panel capacitance detection circuit 50 for detecting capacitance values of liquid crystal capacitor LC of the liquid crystal panel 20 and storage capacitor SC; and a driving voltage adjusting circuit 60. The driving voltage adjusting circuit 60 variably sets the driving voltages VCOM1, VCOM2 to be applied to the common electrodes 6, 7 in accordance with the capacitance values detected by the panel capacitance detection circuit 50.
