Abstract:
The present invention relates to a serial-parallel conversion circuit of a display device.First latch circuits for sampling and latching a serial signal in accordance with sampling pulses outputted from a shift register (31) are provided in association with stages of the shift register (31). In addition, second latch circuits for latching signals outputted from the first latch circuits are provided in association with portions of the stages of the shift register (31). In this case, of all the stages of the shift register (31), the number of stages associated with the second latch circuits is less than the total number of stages of the shift register by two or more.
