Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal display which attenuates generation of wave noise. SOLUTION: A color signal and a timing control signal are input in a timing controller 710. A pulse counting and generating part 712 generates a vertical synchronization starting signal (STV) based on an input vertical synchronization signal (Vsync) and counts the number of pulse of the signal (STV) to provide a counting pulse signal 711 to an integrator 720. The integrator 720 generates an integration signal 721 from the counting pulse signal 711, a comparator 730 provides an inverter control signal 731 generated by comparing the integration signal 721 with a reference signal (REF) to an inverter 400 and a lamp part 500 is driven based thereon.
