Abstract
An embodiment provides a thin film transistor liquid crystal display (TFT-LCD) array substrate comprising a substrate and multilayer array patterns formed on the substrate, and a detecting mark, which is used to detect the size or alignment deviation of one array pattern among the multilayer array patterns and provided in a region of the substrate where the multilayer array patterns are not provided. The detecting mark comprises a detecting area and a detecting pattern which is provided in the same layer as the array pattern to be detected, the detecting pattern is located within the detecting area, and the detecting pattern has transmissivity or reflectivity different from that of the remaining area in the detecting area other than the detecting pattern.
