Abstract

본 발명은 리페어 후 RC 딜레이로 인한 신호 지연의 발생으로 리페어하지 않은 다른 데이터선의 신호와의 광학적 밝기의 차이를 없애는 액정 표시 장치용 박막 트랜지스터 기판에 관한 것이다. 리페어에 따른 신호 지연의 단점을 해결하기 위한 것으로서 데이터선의 초입부에 신호 저항선을 형성하고 보조 신호선을 별도로 형성함으로써, 정상적인 데이터선의 화상 신호의 화소까지의 도달 시간과 리페어한 데이터선의 화상 신호의 화소까지의 도달 시간이 서로 차이가 나지 않도록하여, 리페어에 따른 화소의 광학적 밝기 차이를 없애는 효과가 있다.
