ABSTRACT:
A liquid crystal display apparatus includes a liquid crystal display panel which includes data lines and scanning lines intersecting each other in a matrix arrangement, and a plurality of pixels each including a switching element, a common electrode, and a pixel electrode, with the pixels being disposed at intersections of the data lines and the scanning lines. The apparatus also includes a plurality of signal driver circuits which supply driving voltage signals in accordance with display data to the data lines of the liquid crystal display panel, a scan driver circuit which sequentially selects the scanning lines of the liquid crystal display panel one at time, a power source circuit which supplies power voltages to the signal driver circuits and the scan driver circuit to supply power to the signal driver circuits and the scan driver circuit to enable the signal driver circuits and the scan driver circuit to operate. The signal driver circuits are divided into a first signal driver circuit group and a second signal driver circuit group. The power source circuit supplies a first power voltage to each signal driver circuit in the first signal driver circuit group, and supplies a second power voltage different from the first power voltage to each signal driver circuit in the second signal driver circuit group.
