Abstract: A liquid crystal display device capable of reproducing colors faithfully is provided. The liquid crystal display device includes a color gamut conversion unit that generates an RGB signal for a liquid crystal panel (RGBout), which is provided to a liquid crystal panel, by converting data values of respective colors included in an input RGB signal (RGBin) in accordance with the color gamut of the input RGB signal (RGBin) and the color gamut of the liquid crystal panel. When the color gamut of the input RGB signal (RGBin) is included within the color gamut of the liquid crystal panel, colors represented by the input RGB signal (RGBin) are faithfully reproduced on the liquid crystal panel by providing the RGB signal for liquid crystal panel generated by the color gamut conversion unit to the liquid crystal panel.

Abstract: An auxiliary capacitance electrode driving circuit outputs an auxiliary capacitance electrode driving signal alternating between high potential and low potential once every horizontal scanning period. A common electrode driving circuit drives a common electrode such that it also alternates between high potential and low potential once every horizontal scanning period. In an auxiliary capacitance potential setting circuit, the anode of a diode is connected to an auxiliary capacitance electrode driving signal line and the cathode of the diode is connected to a ground conductor. A node between the anode of the diode and the auxiliary capacitance electrode driving signal line is connected via a capacitor to the auxiliary capacitance electrode driving circuit. Thus, the auxiliary capacitance potential setting circuit functions as a clamping circuit for setting an upper limit of the potential of the auxiliary capacitance electrode.
