摘要:
A liquid crystal display device includes a plurality of pixels each including a liquid crystal element of VA mode and a drive section. The drive section space-divisionally or time-divisionally performs a display drive operation so that the operation includes first and second divisional-drive operation groups. The drive section performs an operation in the first or second divisional-drive operation group, or both thereof. In the former, the output voltage exceeds the input voltage in the intermediate luminance range, whereas in a highlight luminance range, exceeds the input voltage but shows a tendency to be lower compared to in the intermediate luminance range. In the latter, the output voltage is lower than the input voltage in the intermediate luminance range, whereas in a lowermost luminance range, equal to or lower than the input voltage but shows a tendency to be higher compared to in the intermediate luminance range.
