A liquid crystal display device includes a liquid crystal display panel including a plurality of pixels, and a control circuit configured to generate a source signal voltage supplied to each pixel. The liquid crystal display panel includes an active matrix substrate including a pixel electrode applied with a source signal voltage and a common electrode applied with a common voltage.

A degree of symmetry of a gradation level voltage is equal to or lower than 95% at least at one of gradation levels equal to or lower than a 127/255-th gradation level except for the lowest gradation level.

A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is nude higher by super-resolution processing. In this case, the super-resolution processing is performed after frame interpolation processing is performed. Further, in that case, the super-resolution processing is performed using a plurality of processing systems. Therefore, even when frame frequency is made higher, the super-resolution processing can be performed at high speed. Further, since frame rate doubling is performed by the frame interpolation processing, afterimages can be reduced.

In a liquid crystal display device (100), each pixel row group is selected by a common scan signal voltage, each pixel row group including N pixel rows which adjoin one another in a column direction. Where two pixel rows which adjoin each other in a column direction and which are included in different pixel row groups are a first pixel row and a second pixel row, the first pixel row includes a pixel which has a pixel electrode (16) capacitively coupled with a gate bus line (12) which is associated with the second pixel row.

A scan signal voltage supplied to gate bus lines which are associated with the (q+1).sup.th group switches from low to high before a scan signal voltage supplied to gate bus lines which are associated with the q.sup.th group switches from high to low.

The present invention relates to a liquid crystal display (LCD) device which is capable of improving picture quality by switching an optimal gamma voltage and an optimal common voltage on a basis of an operation time, and a method for driving the same. The liquid crystal display device includes a timing controller, a voltage generating unit, a data driver, and a liquid crystal panel. The timing controller can generate voltage control signal for switching initial state to stable state by using certain switching point. The voltage generating unit can receive the voltage control signal, supply the first gamma voltage and the first common voltage during the initial state, and supply the second gamma voltage and the second common voltage during the stable state. The data driver can receive the first gamma voltage in the initial state and the second gamma voltage in the stable state. The liquid crystal panel can suppress short-term residual image if the first gamma voltage and the first common voltage are supplied, and can suppress long-term residual image if the second gamma voltage and the second common voltage are supplied.
