Abstract: The present disclosure provides a display panel, a manufacturing method thereof, and a display device. The display panel includes a display area and a non-display area, and the non-display area has GOA regions. The display panel further includes a first substrate, an array substrate, and an anti-deformation layer. In the present disclosure, the anti-deformation layer is disposed on a lower surface of the first substrate at a position corresponding to the GOA regions. Metal material of the GOA regions is same as metal material of the anti-deformation layer, so that metal expansion coefficient of upper and lower surfaces of the first substrate are same, thereby effectively preventing warpage of the first substrate and the array substrate.

Abstract: A light-emitting substrate and a display device are provided by the present application. The durations of pre-set periods of a plurality of driving circuits decrease along a direction from close to data signal input terminals to away from the data signal input terminals, and/or durations of the pre-set periods of the plurality of driving circuits decrease along a direction from close to first control signal input terminals to away from the first control signal input terminals, which the light-emitting luminance of the light-emitting elements at a near-end and far-end solving a display problem with the display device.
