Zusammenfassung:	PURPOSE: A backlight unit having a double function is provided to supply each light to partial area of an liquid panel and remaining area by a light guiding member, a first light source, a light inducing waveguide, and a second light source, thereby displaying displayed contents to be accurately divided. CONSTITUTION: A light guide member(30) has a first container and a hole corresponding to a partial area to induces the light of a first light source(40) to a remaining area except for partial area of LCD(Liquid Crystal Display) panel(10). A gauge board(90) is displayed on the partial area through the first container and the hole at a location corresponding to the first container and the hole on rear side of the light guide member. A light leading waveguide(50) induces light of a second light source(60) to the gauge board and the liquid panel.
