  Recent theoretical understanding of the vortex phase diagram in real layered
type II superconductors is briefly described in both cases with fields
perpendicular (B \parallel c) and parallel (B \perp c) to the superconducting
layers. The description is based on a high field approximation of the
Lawrence-Doniach model and on a vortex-glass ordering in each case. It is
argued that, generically, the familiar thermal first order transition at B_m(T)
occurs between the vortex liquid region and the so-called vortex slush region,
and that, in systems with stronger fluctuation, most of the thermal first order
line is covered by the first order melting of the Bragg-glass phase. Recent
observations in YBCO in B \parallel c of the vortex slush region and of the
lower critical point of B_m(T) are understood in this way. Based on the same
scenario, recent resistivity data in YBCO and BSCCO, suggestive of the phase
diagram in B \perp c, are explained.
