A shift register comprising at least two shift register units is disclosed, wherein one shift register unit comprises a boost signal thin film transistor, boost driving thin film transistors, depression signal thin film transistors, depression driving thin film transistors and close-up driving thin film transistors. The kind of the shift register increases the number of depression driving thin film transistors and adds the mode that a clock signal is in turn applied every other frame, decreases the duty cycle of depression driving thin film transistors, thus efficiently preventing the biasing effect of depression driving thin film transistors, thereby ensuring the reliability of the shift register unit. A gate driving device and data line driving device for liquid crystal display are still disclosed. |
