  In this paper, results of optical identification of ASCA surveys are
summarized. To understand luminous AGNs in the z<1 universe, the ASCA AGN
sample is still better than samples of AGNs from deep Chandra or XMM-Newton
surveys. Combining the identified sample of AGNs from ASCA Large Sky Survey and
Medium Sensitivity Survey, the sample of hard X-ray selected AGNs have been
expanded up to about 80 AGNs above the flux limit of 10^{-13} erg s^{-1}
cm^{-2} in the 2-10keV band. One fifth of the ASCA AGNs are absorbed
narrow-line AGNs. The luminosity distribution of the absorbed AGNs is limited
below 10^{45} erg s^{-1}, though there are 14 non-absorbed broad-line AGNs are
detected above the luminosity. The result suggests lack of absorbed luminous
AGNs (deficiency of type 2 QSO).
