Abstract: A liquid crystal panel is provided in which rise in temperature of the liquid crystal panel is sufficiently restrained by cooling the liquid crystal panel by means of cooling liquid and exudation of the cooling liquid toward a liquid crystal material is prevented. Cover members 5 and 9 are attached to a liquid crystal panel 1 where the cover members form cavities on the light entering side and on the light emitting side of the liquid crystal panel 1, respectively, cover the liquid crystal panel 1 such that a sealed portion 4 of the liquid crystal material is not in contact with the cavities, and transmit light entering the liquid crystal panel 1 and light emitted from liquid crystal panel 1; and the cavities are filled with cooling liquid CL.

Abstract: A cathode ray tube which provides a favorable quality with a high contrast by reducing the reentrance of reflected electrons into a fluorescent face or stray light. The out wall of the skirt section (3B) of at least the panel section (3) of a cathode ray tube body (2) is coated with a photoabsorbent layer (10), which constitutes a cathode ray tube formed of a material with almost the same refractive index as that of the cathode ray tube body (2).
