Abstract:
The present invention provides a liquid crystal display device with excellent display quality in which the color shift is reduced without increasing power consumption. The present invention relates to a liquid crystal display device including: first pixels and second pixels arranged on a display surface, each pixel including a red sub-pixel, a green sub-pixel, and a blue sub-pixel; a color filter substrate; a liquid crystal layer; and an array substrate, the color filter substrate, the liquid crystal layer, and the array substrate being arranged in the stated order, the color filter substrate including: red color filters, green color filters, and blue color filters, the array substrate including: red sub-pixel electrodes; green sub-pixel electrodes; blue sub-pixel electrodes; first driving signal lines connected to the red sub-pixel electrodes and the green sub-pixel electrodes constituting the first pixels and to the blue sub-pixel electrodes constituting the second pixels; and second driving signal lines connected to the blue sub-pixel electrodes constituting the first pixels and to the red sub-pixel electrodes and the green sub-pixel electrodes constituting the second pixels, wherein AC voltage driving is performed such that, in each first pixel and in each second pixel, a voltage of the same polarity is applied to the red sub-pixel electrode and the green sub-pixel electrode and a voltage of a polarity opposite to that of the green sub-pixel electrode is applied to the blue sub-pixel electrode.
