It stands for the latin word "Amino Domini" which simply means after the year of our Lord Jesus Christ.
It does not stand for his death, as that would mean that Jesus's life had no time marked at all, at least 33 years. In other words, Jesus would be 20 years old in the year 20 AD. Get it? It has nothing to do with His death. Remember this came about years after Jesus was crucified because of His impact on the world. So AD is not the "After Death of Christ" as so many believe.
