A display driving circuit is provided. The display driving circuit includes a multi-stage driving unit, and each stage of the driving unit includes a pull-up control unit and a pull-up unit. The pull-up unit is electrically connected to a second high voltage signal input terminal, so that high voltage signal input from the second high voltage signal input terminal is directly transmitted to a cascade signal output terminal through the pull-up unit, which further enables the display driving circuit to output a high voltage driving signal while a gate of a thin film transistor inside the display driving circuit is kept at low voltage.
