ABSTRACT:
The present invention provides a light guide panel with one or more slanted light guiding parts for backlight units for liquid crystal display (LCD) and for advertisement or illumination, wherein the slanted light guiding part is provided at one side end of the light guide panel, with its one end adjacent to a light source being thicker than the other end adjacent to the light guide panel, to have a slope in which the light emitted from the light source can be totally internal-reflected in the light guide panel, so that the brightness can be maximized and the volume and weight of the light guide panel can be reduced to facilitate its handling and installation, thus resulting in significant reduction of manufacturing expenses.
