The present disclosure provides a test element unit, an array substrate, a display panel, a display apparatus and a corresponding manufacturing method. The test element unit includes: a plurality of layers of test patterns, each layer of test pattern including at least one test block and at least one capacitor being formed between test blocks located in different layers, and, two electrodes of each of capacitors being two test blocks located in different layers, respectively, so that it can determined whether or not corresponding components and devices formed in the display region meet requirements by detecting the test patterns formed in the test region.
