  We perform three-dimensional global non-ideal magnetohydrodynamic simulations
of a protoplanetary disk containing the inner dead-zone edge. We take into
account realistic diffusion coefficients of the Ohmic resistivity and ambipolar
diffusion based on detailed chemical reactions with single-size dust grains. We
found that the conventional dead zone identified by the Els\"asser numbers of
the Ohmic resistivity and ambipolar diffusion is divided into two regions: "the
transition zone" and "the coherent zone". The coherent zone has the same
properties as the conventional dead zone, and extends outside of the transition
zone in the radial direction. Between the active and coherent zones, we
discover the transition zone, the inner edge of which is identical to that of
the conventional dead zone. The transition zone extends out over the regions
where thermal ionization determines diffusion coefficients. The transition zone
has completely different physical properties than the conventional dead zone,
the so-called undead zone, and the zombie zone. The combination of
amplification of the radial magnetic field owing to the ambipolar diffusion and
a steep radial gradient of the Ohmic diffusivity causes the efficient
evacuation of the net vertical magnetic flux from the transition zone within
several rotations. Surface gas accretion occurs in the coherent zone but not in
the transition zone. The presence of the transition zone prohibits mass and
magnetic flux transport from the coherent zone to the active zone. Mass
accumulation occurs at both edges of the transition zone as a result of mass
supply from the active and coherent zones.
