PROBLEM TO BE SOLVED: To provide a lighting apparatus with which a dark spot emerging in the vicinity of the side end face of a light guiding body of an electric discharge tube is alleviated and brightness of light discharged from the light guiding body is virtually made uniform, and to provide a liquid crystal display unit using the same. SOLUTION: A light guiding body 5 is composed of two pieces of cuneiform light guiding members 5a and 5b whose inclined planes are polymerized one upon the other to form a shape of cuboid and straight electric discharge tubes 4a and 4b are arranged closely alongside the thick end faces of respective light guiding members. In addition, light reflex bodies 6a and 6b which reflect the light emitted from both discharge tubes 4a and 4b are arranged together with a light reflex board 7 set under the light guiding body 5 and an optical transducer member 8 set above the light guiding body 5. |
