发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 PURPOSE: To provide a liquid crystal display device which can improve display quality by compensating variation in a duty ratio of a clock signal inputted to a liquid crystal driving circuit, and enabling it to normally take in a video signal. CONSTITUTION: The liquid crystal display device is provided with a liquid crystal element and a liquid crystal driving circuit, and the liquid crystal driving circuit fetches a video signal inputted to the liquid crystal driving circuit into a bus at the timing of changing over from a 1st level to a 2nd level of an internal clock signal or at the timing of changing over from the 2nd level to the 1st level, and selects a voltage to drive the liquid crystal element from video signals taken into the bus, and the internal clock signal is a clock signal which is uniformalized to a prescribed value for both of the 1st and 2nd level periods of an external clock signal inputted to the liquid crystal driving circuit by a clock compensating circuit.
