ABSTRACT:
A lighting apparatus for irradiating a liquid crystal display panel from the back includes a light guiding plate having at least an end which is bent in a direction opposite to the liquid crystal display panel, and a light source disposed on the back surface of the light guiding plate with respect to the liquid crystal display panel. Light from the light source is incident on the bent section of the light guiding plate, reflected by a reflector covering the outside surface of the bent section, and then falls on a section corresponding to a data display space of the liquid crystal display panel. This structure enables an increase in the ratio of the area of a light emitting section to the area of the entire lighting apparatus.
