Display device having blocking circuit for extracting start pulse from signal

摘要

A display device with fewer terminals. The display device includes a timing signal generating circuit which outputs an output signal based on a clock signal, in which one signal line serves as both a signal line to which a start pulse signal that drives the timing signal generating circuit is input and a signal line to which an image signal is input. Further, a blocking circuit which outputs a start pulse to the timing signal generating circuit but does not output the image signal is provided between the signal line and the timing signal generating circuit.
