Abstract
A shift register, a driving circuit and a display device using the same are disclosed. The shift register includes a 1and a 2rectifying elements and 1˜4transistors. 1source/drains of the 1˜3transistors receive a common voltage respectively. The gates of the 1and 3transistors and a 2source/drain of the 2transistor are coupled to a 2terminal of the 2rectifying element. The gates of the 2and 4transistors and a 2source/drain of the 1transistor are coupled to a 2terminal of the 1rectifying element. A 1source/drain of the 4transistor is coupled to a 2source/drain of the 3transistor. The 1terminals of the 1and 2rectifying elements respectively receive input signals and a 1clock signal. A 2source/drain of the 4transistor receives a 2clock signal.
