The present invention relates to a pull-down control circuit and a shift register of using same. In one embodiment, the pull-down control circuit includes a release circuit and four transistors T4, T5, T6 and T7 electrically coupled to each other. The release circuit is adapted for causing the transistor T5 to be turned on and off alternately, thereby substantially reducing the stress thereon, improving the reliability and prolonging the lifetime of the shift register. |
