The present application relates to an array substrate including a display region and a non-display region. The non-display region encapsulates the display region. The non-display region includes a first region and a second region. The first region is configured to dispose trances. The second region is configured to dispose a driving chip assembly. The first region includes a first subregion. Ground wires are disposed in the first subregion. A number of layers of an end of the ground wires close to the second region is less than a number of layers of an end of the ground wires away from the second region.
