Abstract: A cathode ray tube display device including unnecessary radiating magnetic field reducer which improves the ability to reduce an unnecessary radiating magnetic field, especially, generated by a vertical deflection coil. A pair of coil is disposed in opposing relationship on the opposite sides of the ferrite core along an X-axis or in the horizontal direction of the deflection yoke so as to be in contact with an open side end of the ferrite core. Each coil has a shape curved with a predetermined radius of curvature conforming to the shape of the outer peripheral surface of the ferrite core. The ferrite core acts as a magnetic material for the coils which reduces the unnecessary radiating magnetic fields to increase the coil inductances to thereby produce a large extremely low frequency magnetic field (ELMF) reducing effect.

The dynamic beam convergence device includes a spiral coil conductor formed on a non-magnetic film.

Abstract: In a polarization transforming optics having a polarizing beam splitter (PBS) for transforming x-direction incident light flux from a metal halide light source into a single linearly (z direction) polarized light flux beam heading in the y direction and delivering the beam to, preferably, a light valve of a liquid crystal display (LCD) in a coordinate space, the PBS splits the incident light flux from the light source into split light flux beams, separates the split light flux beams into linearly polarized light flux beams having polarizing directions which are orthogonal to each other, and delivers two linearly polarized outgoing light flux beams having polarizing directions which are orthogonal to each other and heading in directions parallel to a polarizing direction plane. One of the two outgoing light flux beams is deflected by a single mirror to have the same heading direction and polarizing direction as those of the other.
