Abstract
The invention discloses an array substrate, a display panel and a display device, and belongs to the field of array substrate test technology, which can solve the problem that the performance of the thin film transistor at the display region of the array substrate in an ADS mode cannot be accurately tested. The array substrate in the invention comprises a plurality of pixel units, each of which comprises a pixel electrode, an insulating layer above the pixel electrode, and a common electrode above the insulating layer, wherein at least one of the pixel units is a test pixel unit, wherein an opening is provided in the insulating layer of the test pixel unit to be above the pixel electrode and separated from the common electrode. The display panel and the display device in the invention comprise the above array substrate.
