| 1. A sustaining circuit comprising a bi-directional device which is connectable to a plasma display panel and includes an
output section for outputting a pulse voltage for driving the panel and connected to the output section,
wherein the bi-directional device includes:
a first transistor including a first substrate formed of a wide bandgap semiconductor and containing an impurity of a first
conductive type, a first electrode formed in a principal surface side of the first substrate, a second electrode formed in
a back surface side of the first substrate and a first control electrode formed in the principal surface side of the first
substrate; and
a second transistor formed of a wide bandgap semiconductor, including a second substrate containing an impurity of a first
conductive type, a third electrode formed in a principal surface side of the second substrate and electrically connected to
the first electrode, a fourth electrode formed in a back surface side of the second substrate, and a second control electrode
formed in the principal side of the second substrate, and the second transistor having the same electric properties as those
of the first transistor, and
wherein the first transistor and the second transistor are stacked so that the respective principal surface sides of the first
substrate and the second substrate face each other.
