Patent number: 8289262Abstract: A liquid crystal display and a shift register device thereof are provided. The shift register device includes a plurality of shift registers connected in series. In the invention, the channel lengths of the transistors, which are responsible to stop outputting scan signal, in the shift register are manufactured greater than the channel lengths of the transistors, which are responsible to output the scan signal, in the shift register. As a result, the degree of influence that the leakage currents of the N-type transistors being responsible to stop outputting the scan signal in the shift register affect the transistors being responsible to output the scan signal when the transistors being responsible to stop outputting the scan signal are in the sub-threshold region is reduced. And thus each of the shift registers is able to output the scan signal normally.Type: GrantFiled: August 18, 2009Date of Patent: October 16, 2012Assignee: Au Optronics CorporationInventors: Tung-Chang Tsai, I-Chun Chen
