Abstract:
1. A liquid crystal display that selectively operates in one of a full screen display mode, in which the full screen of the display panel is set as a display area, and a partial display mode, in which a partial area in the full screen is set as a display area and a remaining area is set as a non-display area, the liquid crystal display comprising: a plurality of gate lines; a plurality of source lines; a plurality of storage capacitor lines that are provided to correspond to the plurality of gate lines; a plurality of pixels that are provided at intersections between the plurality of gate lines and the plurality of source lines; a polarity signal generation circuit that generates a polarity signal corresponding to a frame inversion signal to be repeatedly alternately inverted between a first level and a second level different from the first level frame by frame in the display area, and generates a polarity signal corresponding to a fixed signal fixed at one of the first level and the second level in the non-display area; a storage capacitor line driving circuit that changes the potentials of the storage capacitor lines depending on the polarity signal generated by the polarity signal generation circuit; and a control circuit that changes the display area at a timing according to the frame inversion signal, wherein the control circuit changes the display area in a frame in which the level of the frame inversion signal is different from the fixed signal.
