<p>A cathode ray tube includes far-infrared emitting material therein, and thus emits far-infrared rays useful for human body. The far-infrared emitting cathode ray tube is obtained by including far-infrared emitting material (4) in at least one of a phosphor layer (5), a black matrix (2), an outer graphite layer (12), and a shadow mask (7). This far-infrared emitting cathode ray tube provides a user favorable working surroundings. <IMAGE></p> |
