Shift register and liquid crystal display using same

The present invention relates to a shift register and a liquid crystal display using the same. The liquid crystal display includes a liquid crystal panel, a data driving circuit and a scanning driving circuit. The data driving circuit and the scanning driving circuit each include a shift register. The shift register includes a plurality of shift register units. Two adjacent shift register units respectively receive two inverse clock signals and a VGL signal. Each shift register unit includes a signal output circuit, a signal input circuit, a first logic converting circuit, and a second logic converting circuit. The present shift register and a liquid crystal display have simple structure.
