  We study two Polyakov loop correlators in large $N$ limit of ${\cal{N}}=4$
super Yang-Mills theory at finite temperature using the AdS-Schwarzschild black
hole. In the case that one of the two loops is of the anti-symmetric
representation, we use D5-branes to evaluate them. The phase structure of these
correlators is also examined. A previous result, derived in hep-th/9803135 and
hep-th/9803137, is realized as a limiting case.}
