ABSTRACT:
A shift register, a driving circuit and a display device using the same are disclosed. The shift register includes a 1stand a 2ndrectifying elements and 1st˜4thtransistors. 1stsource/drains of the 1st˜3rdtransistors receive a common voltage respectively. The gates of the 1stand 3rdtransistors and a 2ndsource/drain of the 2ndtransistor are coupled to a 2ndterminal of the 2ndrectifying element. The gates of the 2ndand 4thtransistors and a 2ndsource/drain of the 1sttransistor are coupled to a 2ndterminal of the 1strectifying element. A 1stsource/drain of the 4thtransistor is coupled to a 2ndsource/drain of the 3rdtransistor. The 1stterminals of the 1stand 2ndrectifying elements respectively receive input signals and a 1stclock signal. A 2ndsource/drain of the 4thtransistor receives a 2ndclock signal.
