The Bolton striker hit out at the official following February's goalless draw against Fulham at the Reebok Stadium.
Davies thought he had headed home a late winner for the Trotters, only for the goal to be disallowed as Clattenburg ruled that he had committed a foul on Brede Hangeland.
Davies was left fuming after the match, saying: "Every time he referees us, I don't expect to get anything.
"I think he (Hangeland) got under the ball and I just outjumped him. He hit the floor and he knew it was a fair goal.
"When I saw who the referee was I didn't expect to get anything off him. I have always felt there is something personal there."
Davies has now been found guilty of improper conduct after accepting the charge and requesting a personal hearing.
The FA Commission ordered that he be warned as to his future conduct and fined the sum of £7,500, which is to be suspended in total until the end of the 2011/12 season.
