A liquid crystal display device (100A) according to the present invention includes a pixel (10) including first and second subpixels (10a, 10b) and a first CS bus line (24a), which is associated with the first subpixel. The first subpixel includes a liquid crystal capacitor (13a) and a first storage capacitor (22a). The second subpixel includes a liquid crystal capacitor (13b). A first CS signal voltage applied to the first storage capacitor (22a) through the first CS bus line (24a) is an oscillation voltage, of which one period is shorter than one vertical scanning period, and has first and second potentials that define a maximum amplitude and a third potential between the first and second potentials. When a gate signal voltage Vg supplied to the gate bus line (12) that has been high goes low, the first CS signal voltage Vcsa supplied to its associated first CS bus line (24a) is at the third potential.

摘要:
In a liquid crystal display device performing multi-picture element driving, gate OFF timing of a switching element connected between each sub picture element and a signal line is matched with phase timing when all the subsidiary capacity wires are at the same potential. This prevents the occurrence of uneven luminance appearing in a lateral streak.
