The present disclosure provides an array substrate comprising a structure to be detected disposed on a base substrate. An additional layer for detecting the structure to be detected is broken is disposed below the structure to be detected. The additional layer has a color different from that of the structure to be detected and a same pattern shape as that of the structure to be detected. The present disclosure also provides a detecting method and detecting apparatus of the array substrate described above. According to the array substrate, the detecting method and the detecting apparatus of the present disclosure, an early detection of the breakage defect occurred during the fabrication process of the array substrate can be achieved so as to discover and eliminate those defects as early as possible, which improves throughput and yield. 1.
