Abstract:
A liquid crystal display apparatus comprising:a liquid crystal display panel includingdata lines and scanning lines intersecting each other in a matrix arrangement, anda plurality of pixels each including a switching element, a common electrode, and a pixel electrode,the pixels being disposed at intersections of the data lines and the scanning lines;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; anda 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;wherein the signal driver circuits are divided into a first signal driver circuit group and a second signal driver circuit group; andwherein 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.
