发明名称 Illumination unit and liquid crystal display apparatus comprising same
摘要 A liquid crystal display device comprising a lighting unit of the present invention is aimed to inhibit a liquid crystal panel 111 from breaking by a pressure from a display surface side of a liquid crystal cell 111 , and to inhibit entry of dust having influence on display. Such lighting unit is structured in a way that a fluorescent discharge tube 2 is disposed close to an incident side end face E 1 of a light guiding plate 1 , and the end face E 1 of the light guiding plate 1 and the fluorescent discharge tube 2 , an end face E 2 and a bottom surface of the light guiding plate 1 are covered with a reflecting sheet 3 . A light correction sheet 4 is disposed on an emanating surface of the light guiding plate 1 , and these components are stored in an electrically conductive casing 9 . A spacing H of a space between the light correction sheet 4 and the light guiding plate 1 is set to not larger than one pixel dimension of the liquid crystal cell 111 . The casing 9 has an opening portion J on a light emanating surface side, and a display rear surface side polarizer 13 a of a liquid crystal panel 11 is disposed in direct contact with a front surface of the light correction sheet 4 within the opening portion J.
