ABSTRACT:
A cathode ray tube which emits harmful electromagnetic waves includes far-infrared emitting material which emits far-infrared rays which reduce the harmful effects of electromagnetic waves. The far-infrared emitting cathode ray tube is obtained by including far-infrared emitting material in at least one of a phosphor layer, a black matrix, an outer graphite layer, and a shadow mask. This far-infrared emitting cathode ray tube provides a user favorable work place by reducing the harmful effects of electromagnetic waves.
