    摘要： A liquid crystal display device (100) as an embodiment of the present invention has a plurality of pixels (P), each of which includes subpixels (Spa, Spb) that are defined by subpixel electrodes (124a, 124b), respectively. In each pixel (P), after TFTs (130a, 130b) that have been ON have turned OFF, the average potential of the subpixel electrode (124a) has varied from a potential corresponding to a source signal voltage that was supplied to a source line (Ls) when the TFTs (130a, 130b) were ON. Meanwhile, the average potential of the subpixel electrode (124b) corresponds to the source signal voltage that was supplied to the source line (Ls) when the TFTs (130a, 130b) were ON.
