  Using the X-ray-selected active galactic nuclei (AGN) from the XMM-XXL north
survey and the SDSS Baryon Oscillation Spectroscopic Survey (BOSS)
spectroscopic follow-up of them, we compare the properties of X-ray unobscured
and obscured broad-line AGN (BLAGN1 and BLAGN2; $N_\textrm{H}$below and above
$10^{21.5}$ cm$^{-2}$), including their X-ray luminosity $L_X$, black hole
mass, Eddington ratio $\lambda_{\textrm{Edd}}$, optical continuum and line
features. We find that BLAGN2 have systematically larger broad line widths and
hence apparently higher (lower) $M_{\textrm{BH}}$ ($\lambda_{\textrm{Edd}}$)
than BLAGN1. We also find that the X-ray obscuration in BLAGN tends to coincide
with optical dust extinction, which is optically thinner than that in
narrow-line AGN (NLAGN) and likely partial-covering to the broad line region.
All the results can be explained in the framework of a multi-component, clumpy
torus model by interpreting BLAGN2 as an intermediate type between BLAGN1 and
NLAGN in terms of an intermediate inclination angle.
