Publication number: 20150185530Abstract: The present invention proposes a TFT array substrate, a liquid crystal panel and LCD device. The TFT array substrate includes a transparent substrate, comprising a non-pixel area and a pixel area; multiple TFTs arranged in array in the pixel area; and an alignment mark in the non-pixel area. The alignment mark which is not covered by any insulating material layer is exposed because the insulating material layer on the alignment mark is removed. Therefore, it prevents from an alignment difference caused by a film-color difference between the second and the fourth insulating material layers on the alignment marks caused by uneven film thickness if the distance between the alignment mark in the non-pixel area and the brink of the transparent substrate is narrower than insulating material protecting area (i.e. the alignment mark is out of the insulating material layer protecting area).Type: ApplicationFiled: October 21, 2013Publication date: July 2, 2015Inventors: Yanfeng Fu, Dongzi Gao
