Abstract
Various studies have claimed that the fraction of obscured AGN drops with luminosity, but contrary results are also reported. We present our recent studies on the fraction of X-ray obscured quasars in Chandra Deep Fields and in the local universe showing that most quasars in CDFs (at redshift of 1 ~ 4) are obscured and a consistent pattern in the local universe.
