Liquid crystal display having a source driver and scanning line drive circuit that is shutdown |
摘要 |
A liquid crystal display according to one embodiment of the present invention, comprising: signal lines and scanning lines arranged in first and second directions on an insulation substrate; display elements formed in vicinity of cross points of the signal lines and scanning lines; liquid crystal capacitors and auxiliary capacitors which accumulate electric charge in accordance with voltages of the signal lines via said display elements; a signal line drive circuit which drives the signal lines; a scanning line drive circuit which drives the scanning lines; auxiliary capacitor power supply lines arranged in the first direction, to which one ends of said auxiliary capacitors arranged in the second direction are commonly connected; and auxiliary capacitor power supply line voltage control circuits which control voltages of said auxiliary capacitor power supply lines in sync with a cycle which drives said liquid crystal capacitors and said auxiliary capacitors by polarity reverse, wherein said auxiliary capacitor power supply line voltage control circuit supplies a first reference voltage to all of said auxiliary capacitor power supply lines during a predetermine period after power-on.
