Abstract
A display panel, a manufacturing method thereof and a display apparatus are provided. In some embodiments, the display panel includes a substrate, pixel structures in an array, a protruding ring, an encapsulation layer, and solid sealant. The substrate includes a predetermined hole region, first adjacent region surrounding the hole region, second adjacent region surrounding the first adjacent region, and a display region surrounding the second adjacent region and in which the pixel structures are located. The protruding ring is located in the second adjacent region. The encapsulation layer covers the pixel structures and sides of the protruding ring away from the substrate. The protruding ring and the encapsulation layer covering the protruding ring form a dam. The solid sealant fills the first adjacent region and the hole region enclosed by the dam and is provided with an opening configured to release stress generated by the solid sealant during full curing.
