PROBLEM TO BE SOLVED: To provide a liquid crystsal driving device capable of suppressing the quality of a display picture from being degraded by preventing the effect of the variation in characteristics of amplifier circuits even when there is the vatriation mutually in the characteristics of the amplifiers in a signal driver which has an output circuit part having amplifiers of two systems. SOLUTION: In a signal driver having two systems of an output route which is consisting of a sampling and hold circuit and an amplifier circuit, a field inverting drive inverting the polarity of a signal voltage which is to be applied to pixels for every field and for every scanning line is performed and a drive changing over the selecting of amplifier circuits of two systems for every scanning lines is performed, but, the output route of a first system is selected and the signal voltage is outputted with respect to odd-numbered lines and the output route of a second system is selected and the signal voltage is outputted with respect to even-numbered lines in either of a first field or a second field by making the changing over of the selecting of the amplifier circuits of the two systems so as not to be performed.
