Abstract:
1. A display device comprising: a display panel; a display driving circuit including a shift register formed above the display panel, the shift register including a connection of a plurality of stages, at least one of the stages including a first transistor, a second transistor and a third transistor, the first transistor including a control electrode, an input electrode and an output electrode; a first capacitor connected between the control electrode and the output electrode, the first capacitor holding a voltage of the control electrode; and a clock signal line connected to the input electrode to provide a clock signal as an input into the input electrode; the second transistor connecting the control electrode to a fixed voltage when the second transistor is in an on state, the third transistor holding the second transistor in the on state until the first transistor changes to the on state, wherein the voltage of the control electrode is boosted when the clock signal changes from a low level to a high level, and wherein the second transistor is turned on by an output signal from the next stage.
