The disclosure provides a pixel compensation circuit, a scanning driving circuit and a display device. A control terminal of a first switch and that of a third switch are connected with a scanning line. A first terminal of the first switch is connected with a reference voltage terminal. A second terminal is connected with a first terminal of a second switch. A control terminal of the second switch and that of the fourth switch are connected with a light-emitting control terminal. A first terminal of the third switch is connected with the data cable. A second terminal is connected with a second terminal of the second switch and a control terminal of a driving switch. An anode of a diode is connected with a second terminal of the driving switch. A first terminal of the fourth switch is connected with a first voltage terminal.
