Abstract: The present invention provides an array base plate and a manufacturing method therefor. The array base plate includes a substrate base plate layer, a first trace layer, an insulating layer, and a stress balance layer. The first trace layer includes a first trace. An edge of the stress balance layer is aligned to an edge of the substrate base plate layer. The stress balance layer has a bending stress in a direction opposite to a direction of the first trace and a curvature less than 1.2 mm/m.
