    Abstract: The present application provides an array substrate and a display device. The array substrate includes: a sub-pixel and a data line; a data signal transmission line; a test circuit, in the peripheral region and at a side, away from the display region, of the data signal transmission line, and including a first portion and a second portion, wherein the first portion and the second portion respectively comprise at least one test sub-circuit, and at least a part of the test sub-circuits are electrically connected to the data signal transmission line; a first signal access terminal group, at a side, away from the second portion, of the first portion; a second signal access terminal group, between the first portion and the second portion; and a third signal access terminal group, in the peripheral region and at a side, away from the first portion, of the second portion.
