ABSTRACT:
A liquid crystal display device comprising a lighting unit of the present invention is aimed to inhibit a liquid crystal panel111from breaking by a pressure from a display surface side of a liquid crystal cell111, and to inhibit entry of dust having influence on display. Such lighting unit is structured in a way that a fluorescent discharge tube2is disposed close to an incident side end face E1of a light guiding plate1, and the end face E1of the light guiding plate1and the fluorescent discharge tube2, an end face E2and a bottom surface of the light guiding plate1are covered with a reflecting sheet3. A light correction sheet4is disposed on an emanating surface of the light guiding plate1, and these components are stored in an electrically conductive casing9. A spacing H of a space between the light correction sheet4and the light guiding plate1is set to not larger than one pixel dimension of the liquid crystal cell111. The casing9has an opening portion J on a light emanating surface side, and a display rear surface side polarizer13aof a liquid crystal panel11is disposed in direct contact with a front surface of the light correction sheet4within the opening portion J.
