Abstract
In this invention, disposed in front of a front panel (1a) of a cathode ray tube (1) is a transparent panel (2) through a metal spacer (3) which serves also as a heat radiator, a liquid tight space (5) is formed between the front panel (1a) and the transparent panel (2), a transparent liquid coolant (6) is sealed in the space (5), a protruded portion (3C) is provided on at least the upper end portion of the transparent panel (2) and an extended space (5A) into which the liquid coolant is injected is formed between the protruded portion and the metal spacer (3), whereby it is possible to effectively radiate the heat generated in the front panel (1a) of the cathode ray tube (1).
