A display driving circuit includes a latch circuit provided with a resetting terminal for receiving a pulse signal having a constant period and a setting terminal, a logic product circuit for receiving an output signal of the latch circuit and the pulse signal, a counting circuit having a resetting terminal for receiving an output signal of the logic product circuit and a counting terminal for receiving a clock signal, the counting circuit outputting a data pulse every time a number of pulses of the clock signals reaches a preset constant value from a reception of the output signal of the logic product circuit; and a shift register for receiving the data pulse of the counting circuit at a data signal input terminal thereof and receiving the clock signal at a clock input terminal thereof, the latch circuit being adapted to receive the data pulse of the counting circuit at said setting terminal thereof.
