Former Portugal striker Pauleta, the PSG captain, showed his side the way by opening the scoring from a free kick on three minutes.
Ivory Coast forward Diane made it 2-0 from close range 10 minutes later.
Defender Jean-Pascal Mignot reduced the arrears for the visitors when he headed in a corner on 78 but Diane put the game beyond doubt with his second close-range goal four minutes from time.
PSG stayed third from bottom and in the danger zone but moved level on 38 points with Racing Lens, who lost 3-2 at Le Mans with Japan midfielder Daisuke Matsui scoring twice for the hosts.
