Publication number: 20060274021Abstract: The present invention relates to a display device, and more particularly to a display device in which gate lines and a main gate driver can be repaired. The display device includes a plurality of pixels respectively including a switching element, a gate line connected to the switching element, and first and second gate drivers respectively including a plurality of stages that are interconnected and sequentially generate output signals. Any one of the stages of the first gate driver and any one of the stages of the second gate driver are connected to the same gate line. In this manner, gate drivers that generate the same output are disposed in one gate line on the left and right sides. It is therefore possible to repair disconnected gate lines without using a laser.Type: ApplicationFiled: June 7, 2006Publication date: December 7, 2006Inventors: Dae-Jin Park, Jae-Hyuk Chang, Hyung-Il Jeon, Jong-Hwan Lee, Do-Gi Lim
