What does the seal on Meliodas's forehead mean? How did he get this seal?

Meliodas is the demon king's unholy knight. He violated demon law by
developing an interest in humans and for this betrayal was banished to the
human world to live as a normal human.  
Something went wrong and deeply weakened the seal that contains his ultimate
powers. Little by little his demon powers return. Although he has only a
fraction of his power back and it will take millenia for his powers to return
in full, it has to make you wonder how strong the demon king would be unless
Meliodas IS the demon king himself.

Meliodas is a full demon, and the eldest son of the demon king. He can be
killed (Estarossa stabbed all his hearts) but will come back to life about a
month later. I'm guessing each family of demons has a different mark, so
Zeldris, Estarossa, and Meliodas have the same thing. Say, Derriere has a
different one than them.

The mark signifies that Meliodas and his brothers are from the ruling class as
the demon king has the same seal or you could say it’s because he’s the demon
King’s son. The marks on the others is a representation of their commandments.
