PURPOSE: To turn a deflection current easily into a big current in the state of having the shortened depth while surely realizing a display of a big picture by setting up horizontal and vertical yokes, wherein deflection coil patterns are formed of a superconductor ceramic material on the rear of a panel container part.

CONSTITUTION: Horizontal and vertical deflection yokes 19 and 20 are composed respectively by forming deflection coil patterns of a superconductor ceramic material and these horizontal and vertical deflection yokes 19 and 20 are opposedly set up on the rear part of the panel part of a cathode-ray tube. The deflection yoke parts are set up inside a cooling container, in which liquid nitrogen supplied and circulated. In this case, this big current generates no heat so that a cathode-ray display having a wider angle and the short depth can be realized.
