Abstract: Embodiments of the present disclosure provide a display substrate, a fabrication method thereof, a display panel and a display device. The display substrate includes: a driver circuit board including a plurality of functional film layers; and a planarization layer on the driver circuit board. The display substrate further includes a display region and a first edge region. The first edge region surrounds a periphery of the display region. Part of the functional film layers extends from the display region to the first edge region. The planarization layer extends from the display region to an area of the first edge region that borders the display region. The display substrate includes a flow guide structure disposed on a side of the planarization layer facing away from the driver circuit board, and on at least one side of a boundary of the planarization layer.

Abstract: A display substrate, a method for manufacturing the same and a display device are provided. The display substrate includes a base, a pixel definition layer disposed on the base, and a light-emitting unit disposed in a pixel opening region defined by the pixel definition layer; the display substrate further includes: a diversion channel provided on a surface of the pixel definition layer that is away from the base; and an encapsulation layer covering the light-emitting unit and the pixel definition layer, wherein the encapsulation layer fills the diversion channel. The display substrate in the present disclosure is used for displaying an image.
