A liquid crystal display device comprises a display area including a plurality of pixels arranged in a matrix. A driving unit to drive the plurality of pixels each having a pixel switch is connected to signal lines and scan lines. An auxiliary capacitance voltage is interposed to a pixel electrode connected to the pixel switch through auxiliary capacitance lines arranged along the pixels in a row direction. The driving unit includes an auxiliary capacitance line driving circuit to supply a first voltage, a second voltage smaller than the first voltage and a third voltage smaller than the second voltage to the auxiliary capacitance lines. The voltage difference between the first voltage and the second voltage is smaller than that between the second voltage and the third voltage.
