SHIFT REGISTER AND DRIVING CIRCUIT AND DISPLAY DEVICE USING THE SAME

摘要

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