A display panel and a display device are described herein. The display panel includes a first substrate, a second substrate disposed opposite to the first substrate, and a sealant frame formed between the first substrate and the second substrate. The sealant frame is made of an adhesive substance hardened through a self volatile hardening process or a thermosetting process.
