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.

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.
