PROBLEM TO BE SOLVED: To provide a cascade connection type display driving device in which deterioration in signal quality and an increase in radiation noise are reduced during high-frequency data transfer. SOLUTION: A signal control circuit which has both a signal parallel transfer function of frequency-dividing, dividing, and outputting a signal and a signal transfer function of holding an input frequency and the number of signal lines and outputting with unit magnification to lower the effective data transfer frequency between display driving devices.
