The application discloses an array substrate and a
display device. The array substrate comprises a substrate, an array layer and a conductive
assembly; the substrate comprises a main body part and a connecting part; the array layer is arranged on the substrate and corresponds to at least the main body part, and the array layer is provided with a pixel circuit; the conductive
assembly is arranged on the connecting part of the substrate and is electrically connected with the pixel circuit; wherein the connecting part is arranged at an end of the substrate, and the thickness of the connecting part is smaller than that of the main body part. In the above manner, the reliability of the array substrate can be improved, and the display effect of the display panel can be improved.
