A display motherboard is provided. The display motherboard is provided with barrier walls on at least one of an array substrate or a cover plate in a non-display region, so that stress generated by a cutting will be blocked and released by the barrier walls when the display motherboard is cut. Therefore, the stress will not enter the sealant and the display region, and the stress is released, thereby to prevent microcracks in the sealant and even fractures in films of the display motherboard. Moreover, the stress cannot enter the display region, and the encapsulation of the display region is complete.
