Abstract: A display driving circuit having a shift register is formed on the display panel. The shift register includes a first stage having first and second transistors and a second stage having a third and fourth transistor. A voltage of a control electrode of the first transistor is boosted by a voltage of a first pulse line changing from low to high. In an On state, the second transistor connects the control electrode of the first transistor and a constant voltage line. A voltage of a control electrode of the third transistor is boosted by a voltage of a second pulse line changing from low to high. In an On state, the fourth transistor connects the control electrode of the third transistor and a constant voltage line. The fourth transistor is switched on by a signal from the first stage.

Abstract: A driving circuit of a display device includes first to third output signal lines which are continuously arranged, a first transistor that has a source connected to the second output signal line and a drain connected to a first clock signal line, and a second transistor that provides a non-active potential to a gate of the first transistor when a second clock signal becomes the active potential, wherein a circuit that outputs the active potential to the first output signal line and the third output signal line is disposed at an opposite side to a circuit that outputs the active potential to the second output signal line with a display region interposed therebetween, and wherein the gate of the first transistor is connected to the first output signal line and the third output signal line via rectifying circuits.
