Abstract
An inverter includes first, second, third, fourth, and fifth transistors, and first and second capacitors. The transistors and capacitors are connected in such way that the reverse conduction of the second transistor is prevented through controlling the gate electrode of the second transistor and maintaining the electrical potential at the gate electrode of the fifth transistor by the second capacitor. The electrical potential at the gate electrode of the fifth transistor is maintained stable when a first clock signal changes from high to low (when the first to fifth transistors are NMOS transistors) or from low to high (when the first to fifth transistors are PMOS transistors), so that the output signal of the inverter may not be affected by a change of the first clock signal, thus enabling the inverter to generate a stable output signal and a display panel comprising the inverter to obtain a better display effect.
