PROBLEM TO BE SOLVED: To provide a signal processing circuit of liquid crystal display device capable of improving display quality by avoiding the generation of series irregularity in the display of a liquid crystal panel in a liquid crystal display device performing the phase extension of an input picture signal. SOLUTION: An input picture signal Vin is made display signal VID of a form suitable to be outputted to a liquid crystal panel 5 by performing various signal processings with respect to the input picture signal by the signal processing system of a signal system consisting of aγcorrection circuit 2, an amplifier circuit 3 and a polarity changeover circuit 4. Then, the phase extension of the display signal VID is performed in a phase extending circuit 6 to make the signal phase extended signals VID1∼VID6, which are outputted to 6 lines of parallel signal lines L1∼L6. Thus, series errors at the time of passing the signal through plural systems of signal processing systems are evaded from being generated in a display signal to be outputted to the liquid crystal panel 5 to reduce the series irregularity of a display picture.
