    摘要： An object of the invention is to provide a liquid crystal display device capable of attaining smooth gray scale display and greatly improved display quality, free from the display problems of flicker and the like. The resistance division ratios for gray scale voltage generating resistors provided in the source driver of a source line drive circuit for applying gray scale voltages to pixels via source lines are optimized in accordance with a gray scale display characteristic, and the positive-side voltage resistance division ratios and the negative-side voltage resistance division ratios are set so as to be asymmetrical with one another in consideration of a level shift characteristic.

    摘要： 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.
