The invention relates to a liquid crystal display, a driving circuit and a driving method thereof. The liquid crystal display comprises a liquid crystal display panel, a scanning driving circuit, a data driving circuit and a delay compensation circuit and the liquid crystal display panel comprises a plurality of scanning lines (G<1>,G<2n>), n is a natural number), a plurality of data lines and a plurality of thin film transistors. The scanning driving circuit is used for supplying the scanning signal to the scanning line and the data driving circuit is used for providing the grayscale voltagefor a plurality of the data lines when the scanning line is scanned. The delay compensation circuit is charged when the scanning line G<2i-1> (i is more than or equal to 1 and is less than or equal to n, n is a natural number) is scanned and is discharged when the scanning line G<2i> is scanned, and supplies a high voltage to the scanning line G<2i>, thereby compensating the scanning signal of the scanning line G<2i>.
