A timing generating circuit with low power consumption and a small layout area, a display apparatus including the timing generating circuit as one peripheral driving circuit, and a portable terminal including the display apparatus as a display output section are provided. In the timing generating circuit, which is formed on an insulating substrate and generates output pulses SRFF 1 out to SRFFnout having different frequencies based on a master clock MCK, a clock generating circuit ( 11 ) generates an operating clock having a lower frequency than the master clock MCK frequency. Then, a counter section ( 12 ) operates based on this operating clock and successively outputs shifted pulses S/R 1 out to S/Rmount from shift registers ( 121 - 1 ) to ( 121 -m). An output pulse generating section ( 13 ) generates output pulses SF 1 out to SFnout based on combinations of the shifted pulses S/R 1 out to S/Rmount.
