1. A liquid crystal display comprising:

  • a plurality of pixels disposed in a matrix form, each of the pixel including a TFT element, a liquid crystal element functioning as a main capacitive element, and an auxiliary capacitive element,a gate line selecting a pixel to be driven in a line-sequential manner so that the TFT element in the selected pixel is selectively changed to on-state through application of on-voltage, and selectively changed to off-state through application of off-voltages,a source line supplying an image data to the pixel to be driven through the TFT element, anda drive section driving the pixels for display in a line-sequential manner,wherein one end of the liquid crystal element is connected to one end of the TFT element, one end of the auxiliary capacitive element is connected to the one end of the TFT element while other end of the auxiliary capacitive element is connected to an adjacent gate line, and the drive means refers to image data both of a current unit frame and a previous unit frame, so that,in a normal drive mode, the drive means drives the pixels one by one on the basis of an image data obtained through correction in which image luminance level of the current unit frame is lowered by a predetermined amount, andin an overdrive mode, the drive means drives the pixels one by one on the basis of an image data which allows a larger change of a voltage across the liquid crystal element between the previous unit frame and the current unit frame.
